Ingredients
Cake
- 1/2 cup salted butter, softened
- 2/3 cup applesauce
- 2 eggs
- 1 cup white sugar
- 2 tsp vanilla extract
- 1 cup almond flour
- 1 1/4 cup oat flour
- 2 tsp baking powder
- 1/4 tsp salt
Cinnamon Sugar Filling
- 2 tbsp salted butter, melted
- 1 tbsp oat flour
- 2 tbsp white sugar
- 1/2 tbsp cinnamon
Crumble Topping
- 1/4 cup salted butter, slightly softened (room temperature)
- 1/4 cup light brown sugar
- 1/4 cup almond flour
- 1/2 cup oat flour
- 2 tsp cinnamon
Instructions
- Preheat Oven: Set the oven to 350 degrees Fahrenheit to prepare for baking the coffee cake.
- Mix Cake Ingredients: In a large mixing bowl, combine the softened butter, applesauce, eggs, sugar, and vanilla extract. Then add the almond flour, oat flour, baking powder, and salt. Stir until the batter is smooth and well combined.
- Prepare Cinnamon Sugar Filling: In a separate small bowl, combine the melted butter, oat flour, white sugar, and cinnamon ensuring an even mixture.
- Make Crumble Topping: Add the room temperature butter, light brown sugar, almond flour, oat flour, and cinnamon into a bowl. Mix with your hands or fork until crumbs form. Set aside.
- Assembly – First Layer: Grease or line an 8×8 baking dish. Pour half of the cake batter into the dish and spread evenly. Spoon half of the cinnamon sugar filling on top and swirl it into the batter with a knife or skewer.
- Assembly – Second Layer: Add the remaining cake batter on top of the first layer and spread it evenly. Then add the remaining cinnamon sugar filling on top and swirl again.
- Bake Initial Layer: Place the baking dish in the preheated oven and bake for 25 minutes.
- Add Crumble and Continue Baking: Remove the cake from the oven and evenly distribute the crumble topping over the surface. Gently press the crumble into the batter, especially in the center where the cake may still be underbaked. Return to the oven and bake for an additional 18 minutes.
- Cool and Serve: Remove the cake from the oven and let it cool completely in the pan. Once cooled, cut into squares.
- Enjoy: Serve and enjoy your gluten free cinnamon coffee cake!
