Ingredients for Banana Crumble Coffee Cake (makes 9 slices)

For the Batter:

• 3 medium bananas, mashed (~350g)

• 1 cup Greek yogurt (plain nonfat) (~227g)

• 2 large eggs

• 1 tsp vanilla extract

• 1/4 cup monk fruit, granular (~50g)

• 1 3/4 cups oat flour (~175g)

• 1 tsp baking soda

• 1/2 tsp salt

• 1 tsp cinnamon (optional)

• 1/2 tsp nutmeg (optional)

For the Crumble:

• 1/4 cup oat flour (~25g)

• 1/8 cup monk fruit (~25g)

• 2 tbsp butter (room temperature, grass-fed preferred) (~28g)

• 1/2 tsp cinnamon

Instructions

1. Preheat the Oven and Prepare the Pan:   Preheat your oven to 350°F (175°C). Grease a 9x9 square baking pan with non-stick spray, such as avocado oil, and set it aside.

2. Make the Crumble:   In a small bowl, mix together 1/4 cup oat flour (~25g), 1/8 cup monk fruit (~25g), 2 tbsp butter (~28g), and 1/2 tsp cinnamon. Use a fork to combine until crumbly. Place the mixture in the fridge while preparing the batter.

3. Combine the Wet Ingredients:   In a medium bowl, whisk together 3 mashed bananas (~350g), 1 cup Greek yogurt (~227g), 2 large eggs, and 1 tsp vanilla extract until smooth.

4. Combine the Dry Ingredients:   In another medium bowl, whisk together 1 3/4 cups oat flour (~175g), 1/4 cup monk fruit (~50g), 1 tsp baking soda, 1/2 tsp salt, 1 tsp cinnamon, and 1/2 tsp nutmeg.

5. Mix the Batter:   Add the wet ingredients to the dry ingredients, gently mixing until just combined. Be careful not to overmix, as this can affect the cake's texture.

6. Assemble the Cake:   Pour the batter into the prepared 9x9 baking pan. Remove the crumble mixture from the fridge, break it into small chunks with a fork, and sprinkle it evenly over the top of the batter.

7. Bake the Cake:   Bake for approximately 40 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. Allow the cake to cool in the pan for at least 10-15 minutes before slicing.
