Almond Flour Blueberry Cake Recipe: Moist Crumb and Bursting Berries

This almond flour blueberry cake delivers the perfect balance of tender crumb and juicy berries without a single grain of wheat. 💛 The secret lies in blending almond flour with a touch of coconut flour for structure, while fresh blueberries burst with every bite—no soggy bottoms or dense texture here.

I perfected this recipe after years of baking gluten-free desserts that either crumbled or tasted like cardboard.

The magic starts with the batter: almond flour keeps it rich and moist, while baking powder ensures a light rise. Fresh blueberries are folded in just before baking to preserve their juiciness, and a simple lemon zest glaze ties everything together with bright, citrusy notes.

What you end up with is a cake that’s naturally sweet, subtly nutty, and bursting with berry flavor—no artificial flavors or heavy frostings required.

This recipe is designed for foolproof results—no special equipment, just a standard cake pan and a few simple steps. The cake bakes in 35 minutes to golden perfection, with a tender crumb that holds up beautifully for slicing.

It’s ideal for brunch, dessert, or even breakfast with a dollop of whipped cream. The best part? It tastes even better the next day, making it perfect for meal prep.

While this version is naturally gluten-free and refined sugar-free, I’ve included easy swaps for vegan egg substitutes if needed. Serve it warm with vanilla ice cream or dusted with powdered sugar for a restaurant-worthy finish. Let’s get baking—this cake is a game-changer for anyone craving a lighter, fruit-forward dessert.

Ingredients for almond flour blueberry cake

Moist crumb, bursting berries, and no gluten in sight—here’s what makes this cake shine.

Almond flour is non-negotiable here—Bob’s Red Mill or Anthony’s Goods are my go-tos for consistent texture. The coconut flour is the secret to that tender crumb; don’t skip it. For blueberries, organic frozen works perfectly if fresh are out of season, but toss them in ice water first to keep them plump. The eggs? Room temperature is key—they’ll mix in smoother, and you’ll avoid lumps. If you’re making this ahead, whisk the eggs and sugar first—they’ll emulsify better.

No almond flour? Oat flour or hazelnut flour can work in a pinch, but the flavor won’t be quite the same. Running short on eggs? Flax eggs (1 tbsp ground flax + 3 tbsp water per egg) keep it vegan-friendly. The butter can be swapped for coconut oil or vegan butter, but trust me on the full-fat version—it keeps the cake moist. For the lemon zest, organic lemons have more vibrant flavor, but regular will do. And if you’re worried about soggy bottoms, toss those blueberries in a bit of flour first—it’s a game-changer.

This cake keeps beautifully—3 days at room temperature wrapped in parchment, or 5 days refrigerated in an airtight container. The glaze sets quickly, so make it fresh if you’re serving it right away. I always bake a double batch—it’s perfect for meal prep. Freeze individual slices wrapped in plastic for up to 3 months. Just let them sit at room temperature for 10 minutes before serving—trust me, the texture is worth the wait.

Step-by-step instructions for almond flour blueberry cake

Here's how to bake the perfect almond flour blueberry cake—light, moist, and bursting with juicy berries.

First, toss the 1.5 cups fresh blueberries with 1 tablespoon lemon juice in a bowl. This prevents them from bleeding their color into the batter. Picking over the berries ensures no stems or bruised ones sneak into your cake.

Next, preheat your oven to 350°F. Lightly grease an 8-inch round cake pan with 1 tablespoon extra-virgin olive oil, then line the bottom with parchment paper. I like to use a round pan for even baking, but an 8x8-inch square works too. The oil ensures easy release later—no sticking here!

In a medium bowl, melt the 0.75 cup unsalted butter in 30-second bursts in the microwave, then let it cool slightly to 110°F (just warm to the touch). This prevents scrambling the eggs later. Add the 0.75 cup granulated sugar and whisk until fully dissolved.

Add the 3 whole large eggs one at a time, whisking vigorously after each. Then stir in the 1 tablespoon vanilla extract, 1 tablespoon lemon zest, and 0.5 teaspoon salt. The mixture should be smooth and pale yellow. Here's the thing—room temperature eggs blend better, so if yours are cold, let them sit out for 10 minutes first.

In a separate large bowl, whisk together the 2.5 cups almond flour and 0.25 cup coconut flour. Sift in the 1 teaspoon baking powder and whisk again to remove any lumps. Coconut flour absorbs liquid differently than regular flour, so we handle it gently to avoid developing gluten.

Make a well in the center and pour in the wet ingredients. Stir with a spatula just until combined—don't overmix. You'll see some streaks of flour, and that's perfect. Overmixing develops gluten, which makes the cake dense. Fold in the blueberries gently, reserving any juices from the bowl.

Pour the batter into your prepared pan and smooth the top. Bake for 35-40 minutes until a toothpick inserted in the center comes out clean. The edges should be golden brown, but the top might still look slightly underdone—this is normal for almond flour cakes.

I like to tent the pan with foil after 25 minutes if the top browns too quickly. The cake's done when it springs back slightly when pressed. Let it cool in the pan for 10 minutes, then transfer to a wire rack to cool completely. Patience here prevents a gummy cake!

While the cake cools, whisk together the 0.25 cup powdered sugar with 1-2 tablespoons reserved blueberry juice (or water) until smooth. Drizzle this glaze over the cooled cake—it adds that perfect sweet-tart finish.

Slice into 8 equal wedges and serve immediately. The texture should be tender with a moist crumb, and each bite should deliver bursts of juicy blueberries. Store leftovers in the fridge for up to 3 days, but honestly? This cake disappears fast!

Dietary considerations for this recipe

Gluten-Free Foundation

This cake is naturally gluten-free thanks to the almond and coconut flour blend, making it perfect for those with celiac disease or gluten sensitivity. The almond flour provides rich flavor and moisture, while the coconut flour adds structure without gluten.

I’ve tested this with Bob’s Red Mill almond flour for consistent results—it’s finely ground and free of additives. 🌰

Refined Sugar-Free

The recipe uses only 0.75 cup granulated sugar (about 150g), but you can reduce it by 2 tablespoons if you prefer. For a completely sugar-free version, replace the granulated sugar with 0.5 cup monk fruit sweetener or 0.5 cup erythritol.

The natural sweetness of the blueberries and lemon zest balances the flavor beautifully.

Vegan Egg Substitutes

To make this cake vegan, replace the 3 eggs with 3 flax eggs (mix 1 tbsp ground flaxseed + 3 tbsp water per egg) or 3 aquafaba eggs (whisk ½ cup aquafaba until frothy).

The flax eggs work best for structure, while aquafaba adds a light, airy texture. Let the substitutes sit for 5 minutes before mixing to thicken.

Nut-Free Adaptation

If you’re avoiding nuts, swap the almond flour for oat flour (use 2.75 cups) or a 1:1 gluten-free flour blend like King Arthur Measure for Measure.

The texture will be slightly denser, but it still delivers a delicious blueberry cake. For extra moisture, add 2 tbsp applesauce to the batter.

Dairy-Free Option

Replace the 0.75 cup unsalted butter with 0.75 cup coconut oil (melted) or vegan butter like Miyoko’s. For the glaze, use powdered coconut sugar or more monk fruit sweetener. The flavor stays rich and moist—just as good as the original!
