Instructions

  • Preheat oven to 350 degrees Fahrenheit (175 degrees Celsius) and coat an 8x8 inch baking pan with non-stick spray.
  • Combine almond flour, cinnamon, melted coconut oil, and brown erythritol in a small bowl until the texture resembles coarse crumbs for the streusel.

  • Sift the oat flour, vanilla whey protein, monk fruit sweetener, baking powder, and baking soda into the wet mixture.
  • Fold the dry ingredients into the wet ingredients using a spatula until just combined, ensuring no over-mixing.
  • Spread half of the batter into the prepared baking pan.
  • Evenly distribute half of the streusel mixture over the first layer of batter.
  • Layer the remaining batter on top and finish with the remaining streusel mixture.
  • Bake for 25 to 30 minutes, or until an inserted toothpick emerges clean.
  • Allow the cake to cool in the pan for 10 minutes before slicing into 8 equal portions.
