Ingredients
  

Cake Ingredients
  • 1/2 cup salted butter, softened
  • 2/3 cup applesauce
  • 2 pcs 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
Crumb 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

Method
 

Preparation
  1. Preheat your oven to 350 degrees.
  2. In a large mixing bowl, combine the softened butter, applesauce, eggs, sugar, and vanilla extract. Mix until well blended.
  3. Add the almond flour, oat flour, baking powder, and salt. Combine until smooth.
  4. In a separate bowl, mix the melted butter, oat flour, white sugar, and cinnamon until evenly distributed.
  5. For the crumble topping, add brown sugar, almond flour, oat flour, and cinnamon to the room temperature butter. Use your hands or a fork to form the best crumbles.
  6. Grease or line an 8×8 baking dish. Spread half of the batter evenly in the dish.
  7. Sprinkle half of the cinnamon sugar filling on top and swirl it into the batter.
  8. Add the remaining batter, spread evenly, then top with the last of the cinnamon sugar filling. Swirl it in again.
Baking
  1. Bake for 25 minutes.
  2. Remove from the oven and gently press the crumble topping on top, especially in the middle where it may still be underbaked.
  3. Bake for an additional 18 minutes.
  4. Remove from the oven, let it cool completely, and then cut into squares.

Notes

For serving, dust with powdered sugar, pair with coffee or tea, and add berries or whipped cream for an indulgent twist. Store leftovers in an airtight container in the fridge for 4-5 days or freeze slices tightly wrapped for up to three months. Reheat as needed.
