Ingredients Method

Ingredients

  

• Almond flour (super-fine)
• Whey or whey-casein blend protein powder (vanilla or unflavored)
• Oat flour or finely ground rolled oats
• Baking powder and a pinch of baking soda
• Fine sea salt
• Greek yogurt (2% or 5%)
• Eggs (large)
• Unsweetened almond milk (or dairy milk)
• Avocado oil or light olive oil
• Maple syrup or honey
• Vanilla extract and almond extract (optional but recommended)
• Fresh or frozen blueberries (do not thaw if frozen)
• Sliced almonds (for topping)
• Lemon zest (optional, for brightness)
• Granulated sweetener of choice (optional, for dusting)

Method

 

1. Prep your pan and oven. Heat the oven to 350°F (175°C). Line an 8-inch square pan or 9-inch round pan with parchment and lightly grease the sides. This helps the cake release cleanly and prevents over-browning.
2. Whisk the dry ingredients. In a large bowl, combine 1 1/2 cups almond flour, 1/2 cup whey or whey-casein protein powder, 1/2 cup oat flour, 1 1/2 teaspoons baking powder, 1/4 teaspoon baking soda, and 1/4 teaspoon salt. Break up any clumps with a whisk for an even crumb.
3. Mix the wets. In another bowl, whisk 3/4 cup Greek yogurt, 2 large eggs, 1/3 cup almond milk, 1/4 cup avocado oil, 1/3 cup maple syrup, 1 1/2 teaspoons vanilla extract, and 1/4 teaspoon almond extract. Stir in 1 teaspoon lemon zest if you like a citrus lift.
4. Combine gently. Pour the wet mixture into the dry bowl. Stir with a spatula just until no dry pockets remain. The batter should be thick but scoopable. Avoid overmixing to keep the cake tender.
5. Fold in the blueberries. Toss 1 to 1 1/4 cups blueberries with 1 teaspoon oat flour to prevent sinking. Fold into the batter with a few gentle strokes. If using frozen berries, add straight from the freezer.
6. Pan and top. Spread the batter into the prepared pan. Smooth the top, then sprinkle with 2 to 3 tablespoons sliced almonds. For a pastry-style finish, lightly press a few extra blueberries into the surface.
7. Bake. Bake for 28–35 minutes, or until the top is golden and a toothpick inserted in the center comes out mostly clean with a few moist crumbs. If using a glass pan, start checking at 30 minutes.
8. Cool the cake. Let it cool in the pan for 10 minutes, then lift out using the parchment and cool fully on a rack. This helps the structure set and keeps slices clean.
9. Finish and serve. Dust lightly with your preferred sweetener or a pinch of powdered sugar if desired. Slice into 9 or 12 pieces. Serve plain, or with a spoonful of Greek yogurt and a few fresh berries.

Storage Instructions

• Room temperature: Store covered for up to 24 hours if your kitchen is cool. The almond flour keeps it moist, so don’t leave it out too long.
• Refrigerator: Keep slices in an airtight container for 4–5 days.

  Briefly warm in the microwave or toaster oven to refresh the crumb.

• Freezer: Wrap individual slices in parchment, then place in a freezer bag for up to 3 months. Thaw overnight in the fridge or at room temperature for 30–45 minutes.

Health Benefits

• Higher protein per slice: Whey protein and Greek yogurt add staying power, helping curb mid-afternoon cravings and support muscle repair.
• Better fats: Almond flour brings heart-friendly monounsaturated fats and vitamin E, which supports skin and immune health.
• Lower glycemic load: Almond and oat flours slow down digestion compared to white flour, offering a steadier energy release.
• Fiber and antioxidants: Blueberries deliver fiber and anthocyanins, linked to brain and cardiovascular health.
• Gluten-lite approach: Using almond and oat flours makes it wheat-free if you use certified gluten-free oats and a gluten-free protein powder.

What Not to Do

• Don’t overmix the batter. Vigorous stirring develops a dense, rubbery texture, especially with protein powder in the mix.
• Don’t overload with berries. More than 1 1/4 cups can make the cake soggy and cause collapse in the center.
• Don’t swap whey for pure collagen. Collagen behaves differently and can make the texture gummy. Stick to whey or a whey-casein blend.
• Don’t crank up the heat. Higher oven temperatures brown the almonds too fast and leave the center underbaked.
• Don’t skip pan prep. Almond flour sticks.

  Parchment and a light grease save you from torn slices.

Recipe Variations

• Lemon Poppy Seed Blueberry: Add 1 extra teaspoon lemon zest and 1 tablespoon poppy seeds. Swap almond extract for more vanilla.
• Cinnamon Crumble Top: Mix 2 tablespoons almond flour, 1 tablespoon oat flour, 1 tablespoon coconut sugar, 1 tablespoon cold butter or coconut oil, and 1/2 teaspoon cinnamon. Sprinkle over before baking.
• Dairy-Free: Use a plant-based Greek-style yogurt and a pea or rice protein blend.

  Note: texture will be slightly denser; add 1–2 extra tablespoons almond milk if needed.

• Chocolate Almond Blueberry: Stir in 2 tablespoons mini dark chocolate chips and 1 tablespoon cocoa powder; bump maple syrup by 1 teaspoon to balance.
• Nut-Free (almond flavor, no nuts): Replace almond flour with finely milled sunflower seed flour and skip the sliced almonds. Add a drop more almond extract for aroma.
• Extra Protein Boost: Add 2 more tablespoons protein powder and 1 tablespoon almond milk to keep the batter supple.

FAQ

Can I use coconut flour instead of almond flour?

No. Coconut flour is highly absorbent and would make the cake dry and crumbly.

If you must use it, you would need a totally different ratio of liquids and eggs. Stick to almond flour or a 1:1 sunflower seed flour swap.

What kind of protein powder works best?

Whey or a whey-casein blend gives the best rise and softness. Unflavored or vanilla works well.

Plant proteins can be used, but you may need a splash more milk and a minute or two longer bake time.

Can I reduce the sweetener?

Yes. You can drop maple syrup to 1/4 cup and add 1–2 tablespoons granulated sweetener to keep structure. The cake will be less sweet but still pleasant, thanks to the berries.

Do frozen blueberries work?

Absolutely.

Use them straight from the freezer and fold in gently. Don’t thaw, or they’ll bleed and turn the batter grayish.

How do I know it’s done?

Look for a golden top, set edges, and a toothpick that comes out with a few moist crumbs. If the center jiggles, give it 3–5 more minutes and tent with foil if browning too fast.

Can I make muffins instead?

Yes.

Portion the batter into a lined 12-cup muffin tin and bake at 350°F (175°C) for 18–22 minutes. Start checking at 18 minutes.

Is this cake good for breakfast?

It’s a balanced option with protein, fiber, and better fats. Pair a slice with a scoop of Greek yogurt or a boiled egg for a more complete breakfast.

How can I prevent berries from sinking?

Toss them with a teaspoon of oat flour before folding in, and spread a thin layer of batter in the pan before adding the rest.

Using smaller berries also helps.
