Ingredients

Oatmeal Base

1 ¾ cups rolled oats
½ cup butter, room temperature
¼ cup honey

Cottage Cheese Filling

2 medium eggs, room temperature
1 ⅔ cups cottage cheese
½ cup Greek yogurt
1 cup fresh blueberries
5 tablespoons cornstarch
2 tablespoons brown sugar (optional)

Directions

1. Preheat your oven to 400°F (200°C). Line an 8-inch round cake pan with baking paper and lightly grease it with butter or oil.
2. In a shallow bowl, combine the rolled oats, room temperature butter, and honey. Mix thoroughly until the oats are evenly coated and sticky.
3. Press the oat mixture firmly into the bottom of the prepared cake pan. Use the back of a spoon to level and compact the crust.
4. Bake the oatmeal base for 15 minutes, or until lightly golden. Remove from the oven and allow it to cool slightly.
5. While the crust is baking, whisk the eggs in a medium bowl until foamy.
6. Add the cottage cheese and Greek yogurt to the eggs. Blend or whisk thoroughly until smooth and creamy.
7. Stir in the cornstarch and brown sugar, mixing until fully incorporated.
8. Gently fold in the blueberries, distributing them evenly throughout the mixture.
9. Pour the cottage cheese filling over the slightly cooled oatmeal crust.
10. Return the cake to the oven and bake for 30 to 35 minutes, or until the top is set and lightly golden.
11. Remove from the oven and allow the cake to cool in the pan for 30 to 60 minutes before slicing and serving.

Variations

For extra protein, add 1 scoop of unflavored or vanilla protein powder to the filling. If using protein powder, add 1 to 2 tablespoons of milk to maintain a smooth consistency.

For added crunch, mix 2 tablespoons of chopped walnuts or pecans into the oatmeal base.

For a lower-carb option, replace ¾ cup of the oats with ½ cup almond flour and use a sugar-free sweetener instead of brown sugar.

You can substitute blueberries with raspberries, diced strawberries, or a mix of berries for a different flavor profile.

Add 1 teaspoon of vanilla extract or a bit of lemon zest to enhance the flavor of the filling.

Storage/Reheating

Store leftover cake in an airtight container in the refrigerator for up to 5 to 6 days. Because the filling contains dairy, do not leave it at room temperature for more than 2 hours.

For longer storage, wrap individual slices tightly and freeze for up to 3 months. Thaw overnight in the refrigerator before serving.

You can enjoy the cake chilled straight from the fridge or warm individual slices in the microwave for 15 to 20 seconds for a softer texture.

FAQs

Can I use quick oats instead of rolled oats?

Yes, quick oats will work, though the crust will have a softer texture compared to rolled oats.

Can I replace cottage cheese with ricotta?

Yes, ricotta cheese can be used as a substitute and will provide a similar creamy consistency.

How do I make this recipe dairy-free?

Use plant-based butter, dairy-free yogurt, and silken tofu in place of cottage cheese.

Why is my filling watery?

Can I use frozen blueberries?

How do I know when the cake is done?

Can I make this cake ahead of time?

Yes, it can be made a day in advance and stored in the refrigerator until ready to serve.

What size pan works best?

An 8-inch round cake pan provides the ideal thickness and baking time for this recipe.

Can I reduce the sweetness?

Yes, you can reduce or omit the brown sugar and slightly decrease the honey if you prefer a less sweet dessert.

Is this cake suitable for a high-protein diet?

Yes, thanks to the cottage cheese and Greek yogurt, it provides a moderate protein boost compared to traditional cheesecake.
