  • 1/2 cup butter, softened
  • 1 cup allulose
  • 2 eggs
  • 1/2 tsp vanilla
  • 3/4 cup almond flour
  • 1/3 cup cocoa powder
  • 1/2 tsp baking powder
  • 1/4 tsp salt
  • 1/3 cup Lily’s semi-sweet chocolate chips
  • 3 tbsp natural peanut butter


  • Preheat the oven to 350 degrees F. Grease an 8x8 baking dish.
  • In a large mixing bowl, stir together the butter and allulose until light and fluffy. Whisk in the eggs and vanilla.
  • Add the almond flour, cocoa powder, baking powder, salt, and chocolate chips. Stir until combined, then pour the brownie batter into the baking dish.
  • Drizzle or dollop the peanut butter on top of the brownie batter. If the peanut butter is too thick, put it in the microwave for about 30 seconds until it is thinner and easy to work with. Take a knife and swirl the peanut butter throughout the brownie batter.
  • Place in the oven and bake at 350 for 20 minutes, or until a knife pulls out clean from the brownie part (it’s ok if the peanut butter is still sticky). Let cool in the pan, the enjoy.


  • These brownies are a bit crumbly, so they’re best enjoyed on a plate with a fork.
  • This recipe makes 16 small brownies (when cut 4x4) or 9 large brownies (when cut 3x3).
