Best Flourless Lemon Yogurt Cake | Naturally Gluten-Free
This Best Flourless Lemon Yogurt Cake is the recipe that proves you do not need flour to make a cake that is genuinely satisfying โ dense without being heavy, bright with lemon throughout the crumb rather than just in the glaze, and with a moist, almost custardy interior that comes from almond flour and Greek yogurt working together in place of the wheat flour structure most cakes depend on.
It is naturally gluten-free, high in protein from the almonds and yogurt, and pulls together from one bowl in about 15 minutes of active work โ qualities that make it genuinely useful for weeknight baking rather than a special-occasion recipe that happens to be worth the effort. The lemon is in the cake itself, in the glaze, and in the yogurt base, which means the citrus flavour is layered and persistent rather than a superficial note that bakes off.
This is the flourless cake that you make once and then return to because nothing in the regular flour-based repertoire quite replicates what almond flour does to a lemon cake’s texture โ the crumb is finer, the moisture more even, and the flavour somehow cleaner and more concentrated than an equivalent cake made with all-purpose flour.
Why Almond Flour and Yogurt Together Make This Work
Almond flour provides the structure and the fat that flour and butter would normally contribute separately โ it is both the dry structural component and a significant fat source, which is why flourless cakes made with almond flour are richer and more moist than their ingredient list suggests they should be. The finely ground almonds also trap moisture within the crumb during baking and prevent the drying that makes flour-based cakes go stale quickly.
Greek yogurt adds both protein and lactic acid โ the acid reacts with the baking powder to create lift, and the protein contributes to the set crumb structure that holds the cake together without gluten’s help. Together they produce a cake that is denser than a standard sponge but lighter than a traditional almond cake, and that stays moist at room temperature for four to five days without any perceptible staling.
- Prep Time: 15 minutes
- Cook Time: 38 to 42 minutes
- Total Time: 55 minutes, plus cooling
- Yield: one 9-inch round cake, 10 to 12 slices
What You Need
For the cake:
- Blanched almond flour, finely ground: 2 cups (200g) โ blanched is essential; almond meal made from skin-on almonds produces a coarser, slightly bitter cake
- Baking powder: 1 teaspoon
- Baking soda: 1/4 teaspoon
- Fine sea salt: 1/4 teaspoon
- Large eggs: 3, at room temperature
- Full-fat plain Greek yogurt: 3/4 cup (180g)
- Granulated sugar: 3/4 cup (150g)
- Olive oil or neutral oil: 1/4 cup (60ml)
- Fresh lemon juice: 3 tablespoons (about 1.5 lemons)
- Lemon zest: 2 teaspoons (from 2 lemons)
- Pure vanilla extract: 1 teaspoon
For the lemon glaze:
- Powdered sugar, sifted: 1 cup (120g)
- Fresh lemon juice: 2 to 3 tablespoons
- Lemon zest: 1/4 teaspoon
Optional garnish:
- Flaked almonds, lightly toasted
- Thin lemon slices
- Powdered sugar dusted over the top instead of glaze
How to Make It
- Preheat the oven to 350ยฐF (175ยฐC) and grease a 9-inch round cake pan generously, then line the base with a circle of parchment paper โ flourless cakes are more delicate than flour-based ones when warm and the parchment ensures clean removal.
- Whisk the almond flour, baking powder, baking soda, and salt together in a large bowl until no clumps remain โ almond flour has a tendency to clump and those clumps don’t break down during mixing the way flour clumps do.
- In a separate bowl, whisk the eggs, Greek yogurt, sugar, olive oil, lemon juice, lemon zest, and vanilla extract together until completely smooth and uniform.
- Pour the wet ingredients into the almond flour mixture and fold gently with a spatula until just combined โ the batter will be thicker than a standard cake batter and slightly grainy-looking from the almond flour, which is correct.
- Pour the batter into the prepared pan and smooth the surface evenly โ it will not level itself in the oven as a flour-based batter might.
- Bake for 38 to 42 minutes until the top is deep golden brown and a toothpick inserted into the center comes out with a few moist crumbs rather than wet batter. The top will dome slightly and then settle flat as it cools.
- Cool in the pan on a wire rack for 20 minutes before turning out onto the rack to cool completely โ the cake is fragile while warm and needs the full 20 minutes in the pan before it is firm enough to handle.
- Once fully cooled, whisk the sifted powdered sugar, lemon juice, and zest together into a smooth, pourable glaze and spoon or drizzle over the surface of the cake, letting it run naturally down the sides.
- Scatter toasted flaked almonds and arrange lemon slices over the wet glaze if using, and let the glaze set for 15 minutes before slicing.
If you love the Greek yogurt as a baking ingredient direction, our Greek Yogurt Banana Bread uses the same yogurt-as-moisture principle with a completely different fruit โ both are genuinely better bakes for having yogurt in them, and both improve on day two as the yogurt’s lactic acid continues to tenderise the crumb in the container.
What Makes the Texture of This Cake Unique
The density of an almond flour cake comes from the absence of gluten โ without gluten’s stretchy protein network, the cake has no capacity to trap and hold the air bubbles that make a flour-based sponge light and airy. What it has instead is a more even, consistent crumb with no large air pockets, a slightly fudgier interior quality, and a moisture retention that lasts significantly longer than gluten-based cakes.
The Greek yogurt in this recipe provides more than moisture โ its protein content forms a loose secondary network that helps the cake hold together in the absence of gluten, and the lactic acid interacts with the baking powder to create the lift that gives this cake a proper dome rather than sitting flat in the pan. Without the yogurt’s acid, the baking powder alone in an almond flour batter produces significantly less rise.
Olive oil rather than butter is worth the specific choice here โ butter’s water content creates steam during baking that can make a delicate flourless crumb slightly gummy, while oil produces a consistently moist, clean texture. The olive oil also adds a subtle, almost grassy richness that complements lemon in a way that neutral oils don’t โ not olive-flavoured, just slightly more complex. According to King Arthur Baking, oil-based cakes retain moisture longer than butter-based ones because oil remains liquid at room temperature while butter solidifies, preventing the hardening of the crumb that makes butter cakes feel drier after the first day.
What to Serve Alongside This Cake
A spoonful of lightly sweetened fresh Greek yogurt alongside each slice is the most natural accompaniment โ it mirrors the yogurt inside the cake and adds a cool, tangy contrast to the lemon glaze on top.
For a full afternoon tea or brunch spread, this cake alongside our Healthy Blueberry Yogurt Cake gives guests two yogurt-based, naturally lighter cakes in genuinely different flavour directions โ the blueberry cake is softer and more muffin-like while this flourless version is denser and more custardy, together covering the full range of what yogurt baking can produce.
For an elegant plated dessert with berries, serve a slice of this cake with a small pile of fresh raspberries or blueberries alongside and a dusting of powdered sugar โ the berry acidity and the lemon in the cake are natural flavour companions, and the simple presentation looks composed without requiring any additional preparation.
Variations That Stay in the Flourless Spirit
Replace the lemon juice and zest with orange juice and zest for a flourless orange yogurt cake that is sweeter, slightly less sharp, and works particularly well with a dark chocolate drizzle over the glaze rather than flaked almonds โ chocolate and orange is a more indulgent combination than chocolate and lemon while using the identical method.
Add 1/4 cup of finely ground pistachios to the almond flour mixture for a pistachio-lemon version that produces a cake with green flecks throughout the crumb and a more complex, slightly sweet-nutty base underneath the lemon โ look for roasted unsalted pistachios and grind them yourself rather than using pre-ground pistachio flour, which tends to be gritty.
Stir 2 tablespoons of poppy seeds into the batter for the classic lemon-poppy seed direction that adds a gentle textural crunch and a slightly nutty flavour โ the poppy seeds complement almond flour well since they contribute a similar nutty note without competing. Our Healthy Blueberry Yogurt Cake has a poppy seed variation in its recipe that uses the same technique if you want to see how the addition changes a similar cake.

| Protein | 8 g |
| Carbohydrates | 28 g |
| Fats | 16 g |
These values are estimates based on the full recipe with glaze divided by 10 slices. The protein count is notably high for a cake slice โ 8 grams comes from the combination of almond flour (approximately 6 grams per 100g), eggs, and Greek yogurt, all present in generous quantities. The fat is primarily from the almond flour and olive oil, both of which are unsaturated fat sources.
Storing This Cake at Its Best
Store the fully cooled cake covered at room temperature for up to 4 days โ the almond flour and yogurt combination genuinely keeps this cake moist longer than a standard flour-based equivalent. The lemon flavour deepens overnight as the zest’s oils continue to perfume the crumb, which makes day-two slices noticeably more flavourful than day-one.
The unglazed cake freezes very well โ wrap individual slices or the whole cake tightly in plastic wrap and freeze for up to 2 months. Thaw overnight at room temperature and glaze after thawing rather than before freezing for the freshest-looking finish. The texture after thawing is essentially identical to fresh-baked, which makes this one of the best cakes to batch-bake and freeze.
Where This Cake Can Go Wrong
Using almond meal rather than blanched almond flour produces a coarser, more rustic crumb with a slightly bitter note from the almond skins โ the two are labelled differently at most stores and the distinction matters significantly for this recipe. Blanched almond flour looks fine, pale, and almost powdery; almond meal is darker and visibly coarser. Use the fine-ground blanched version.
Not cooling the cake for the full 20 minutes in the pan before attempting to unmold produces a cake that cracks along the top and crumbles at the edges โ without gluten’s structural strength, a warm almond flour cake is significantly more fragile than a warm wheat cake and needs the in-pan cooling period to firm enough to handle. The parchment base is the safety net that catches any crumbling during the turn-out.
Over-baking until the toothpick comes out completely clean produces a dry, slightly sandy crumb โ almond flour cakes finish baking at a higher moisture level than flour-based ones, and the correct doneness is moist crumbs clinging to the toothpick rather than nothing at all. The residual heat after the cake comes out of the oven will continue setting the crumb for another 10 to 15 minutes, which is why pulling it slightly underdone produces a perfectly moist result once cooled.
Best Flourless
Lemon Yogurt Cake
Dense without being heavy, bright with lemon throughout the crumb โ moist, almost custardy from almond flour & Greek yogurt. One bowl, 15 minutes active, naturally gluten-free.
Ingredients
Instructions
Preheat to 350ยฐF (175ยฐC). Grease 9-inch round pan generously, line base with parchment โ flourless cakes are delicate when warm and parchment guarantees clean removal.
Whisk almond flour, baking powder, baking soda, and salt until no clumps remain. Break up almond flour clumps โ they donโt dissolve like wheat flour.
In separate bowl, whisk eggs, Greek yogurt, sugar, olive oil, lemon juice, lemon zest, and vanilla until completely smooth and uniform.
Pour wet into dry and fold gently with spatula until just combined. Batter will be thicker than standard cake and slightly grainy โ correct.
Pour into prepared pan and smooth surface evenly โ it wonโt level itself in the oven.
Bake until top is deep golden and toothpick comes out with a few moist crumbs (not wet batter, not bone-dry). Top will dome then settle flat as it cools.
Cool on wire rack 20 min before turning out to cool completely. Warm flourless cake is fragile โ donโt rush the in-pan set.
Whisk sifted powdered sugar + 2โ3 Tbsp lemon juice + ยผ tsp zest to smooth pourable glaze. Spoon/drizzle over fully cooled cake, letting it run down sides.
Kitchen Notes
Use fine blanched almond flour, not almond meal. Meal (skin-on) is coarser, darker, and slightly bitter.
Pull when toothpick shows moist crumbs. Bone-dry = sandy crumb. Residual heat sets it 10โ15 min after out.
20 min in pan + parchment prevents cracking/crumbling. Warm = fragile without gluten.
Olive oil stays liquid at room temp so crumb stays moist longer; butter solidifies and dries it out. Adds subtle grassy richness.
Yogurtโs lactic acid reacts with baking powder for dome; protein helps set crumb without gluten. Donโt skip.
Orange + chocolate drizzle, +ยผ cup ground pistachios, or +2 Tbsp poppy seeds โ same method.
Storage & Serving
Covered, up to 4 days. Stays moist โ lemon deepens overnight (day-two is more flavorful).
Freeze unglazed, wrapped tight, up to 2 months. Thaw at room temp overnight, then glaze fresh. Texture = identical.
Batter mixes in 15 min from one bowl โ ideal weeknight bake.
- Lightly sweetened Greek yogurt alongside
- Fresh raspberries or blueberries + powdered sugar
- Pair with Healthy Blueberry Yogurt Cake for brunch spread
- Afternoon tea with berries, no extra prep
