Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1 cup plain 0% Greek yogurt
3 eggs
1 brown banana, mashed
3 tablespoons maple syrup
1/4 cup olive oil
1 teaspoon vanilla extract
2 cups oat flour
1/2 cup collagen powder, unflavored protein powder, or additional oat flour
1.5 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1 teaspoon cinnamon
For the crumble topping:
1/3 cup coconut sugar or brown sugar
2/3 cup oat flour or oats
1 teaspoon cinnamon
3 tablespoons butter, room temperature
For the white chocolate topping:
1 ounce baker’s white chocolate
1 tablespoon milk
1 to 2 teaspoons vanilla protein powder, optional
Directions
Preheat the oven to 350°F and line an 8×8-inch baking dish with parchment paper.
In a medium bowl, whisk together the Greek yogurt, mashed banana, maple syrup, olive oil, vanilla extract, and eggs until smooth and combined.
In a separate bowl, whisk together the oat flour, collagen or protein powder, baking powder, baking soda, salt, and cinnamon.
Slowly add the dry ingredients to the wet ingredients and stir until fully combined. Set the batter aside.
To make the crumble topping, combine the coconut sugar, oat flour, cinnamon, and butter in a medium bowl. Use a fork or your fingers to mix until a crumbly texture forms and no loose flour remains.
Spread half of the batter into the prepared baking dish. Sprinkle half of the crumble topping over the batter. Repeat with the remaining batter and finish with the rest of the crumble topping.
Bake for 35 to 45 minutes, or until a toothpick inserted into the center comes out clean. Cooking time may vary slightly depending on the protein powder used.
To prepare the white chocolate topping, place the white chocolate in a microwave-safe bowl and microwave for about 45 seconds, repeating if necessary until melted. Stir in the milk and whisk until smooth. Add vanilla protein powder if you would like a thicker glaze.
Allow the coffee cake to cool before drizzling with the white chocolate topping. Slice into 9 pieces and serve.
