Method
Preparation
- Preheat your oven to 350 degrees.
- In a large mixing bowl, combine the softened butter, applesauce, eggs, sugar, and vanilla extract. Mix until smooth.
- Add the almond flour, oat flour, baking powder, and salt to the mixture. Combine until smooth.
- In a separate bowl, mix together the melted butter, oat flour, white sugar, and cinnamon evenly.
- For the crumble topping, combine the brown sugar, almond flour, oat flour, and cinnamon with the room temperature butter using your hands or a fork until crumbles form. Set aside.
- Grease or line an 8x8 baking dish. Pour half of the cake batter into the dish and spread it evenly.
- Add half of the cinnamon sugar filling on top and swirl it into the batter.
- Spread the remaining half of the cake batter evenly on top. Finally, add the rest of the cinnamon sugar filling and swirl it in.
Baking
- Bake for 25 minutes.
- After baking, gently place the crumble topping on top and press it into the cake, especially in the middle where it might still be underbaked.
- Bake for another 18 minutes.
- Remove from the oven, let it cool completely, and then cut into squares.
Notes
Serve warm with a cup of coffee or tea. Enjoy plain or with a sprinkle of powdered sugar. To store, keep the cake in an airtight container at room temperature for up to three days, refrigerate for up to a week, or freeze tightly wrapped for longer storage. Measure flours carefully to avoid a dense cake and ensure butter is at room temperature for easier mixing.
