Ingredients You’ll Need
The Dry Base
- 2 cups rolled oats: You can use old-fashioned rolled oats or pulse half of them in a blender for a finer, more traditional cake texture.
- 1 ½ tsp baking powder & ½ tsp baking soda: For an even, airy rise.
- 1 ½ tsp ground cinnamon: Adds warmth and complements the berries.
- ¼ tsp fine sea salt: Balances the sweetness.
The Wet Ingredients
- 2 large eggs: Room temperature works best (or sub with 2 flax eggs for a vegan option).
- ½ cup pure maple syrup: Can be swapped for raw honey or agave nectar.
- ¾ cup plain Greek yogurt: Keeps the cake moist and adds a hit of protein (sub with unsweetened applesauce or mashed banana for dairy-free).
- ½ cup milk of choice: Almond, oat, soy, or dairy milk all work seamlessly.
- 1 tbsp melted coconut oil or butter: Adds richness to the crumb.
- 1 tsp pure vanilla extract: For that classic bakery aroma.
The Star Ingredient
- 1 ½ cups blueberries: Fresh or frozen. If using frozen, fold them in directly without thawing to keep the batter from turning completely purple.
Step-by-Step Instructions
Step 1: Prep the Oven and Pan
Preheat your oven to 180°C (350°F). Lightly grease an 8-inch or 9-inch round cake pan (or a cast-iron skillet) with coconut oil, or line it with parchment paper for effortless removal.
Step 2: Combine the Dry Ingredients
In a large mixing bowl, whisk together the rolled oats, baking powder, baking soda, ground cinnamon, and sea salt until evenly distributed.
Step 3: Whisk in the Wet Ingredients
Make a well in the center of the dry oats and pour in the eggs, maple syrup, Greek yogurt, milk, melted coconut oil, and vanilla extract. Stir well with a wooden spoon or spatula until a thick, uniform batter forms.
Step 4: Fold in the Blueberries
Gently fold in 1 ¼ cups of the blueberries, saving the remaining ¼ cup to scatter over the top just before baking.
Step 5: Bake to Golden Perfection
Pour the batter into your prepared pan and smooth the surface. Press the remaining blueberries into the top. Bake for 32 to 36 minutes, or until the top is golden-brown and a toothpick inserted into the center comes out clean.
Step 6: Cool and Slice
Let the cake rest in the pan for 10 minutes to set, then transfer to a wire rack or wooden board. Slice into wedges and serve warm!
Pro Baker Tips
- Toss frozen berries in a pinch of oat flour: If your frozen berries tend to sink to the bottom, lightly coat them in half a teaspoon of oat flour before folding them into the batter.
- Add nuts for crunch: Fold in ¼ cup of chopped walnuts or sliced almonds for added texture and healthy fats.
- Serving suggestion: Serve warm with a spoonful of Greek yogurt, a drizzle of creamy almond butter, or a splash of warm maple syrup.
Storage & Freezing Instructions
- Countertop: Store covered with a clean tea towel for up to 24 hours.
- Refrigerator: Store in an airtight container for up to 5 days. Reheat slices in the toaster oven or microwave for 15 seconds before eating.
- Freezer: Slice the cooled cake, wrap individual pieces in parchment paper, and store in a freezer-safe bag for up to 3 months. Thaw overnight in the fridge or warm directly from frozen.
