Coffee Cake


  • ¼ cup brown sugar
  • 1 tbsp ground cinnamon

Crumble Nut Topping

  • ½ cup almond flour
  • ½ cup chopped walnuts
  • ¼ cup brown sugar
  • ½ cup ghee room temp
  • 1 tbsp ground cinnamon

Optional Glaze:

  • 1 cup powdered sugar
  • 1-3 tbsp milk (I used unsweetened vanilla almond milk)


  • Preheat the oven to 350°F. Lightly grease a 9x9 baking pan and line with parchment paper.
  • Make the filling: In a small bowl, mix together the brown sugar and cinnamon. Set aside.
  • Make the crumble topping: In a medium bowl, add the almond flour, chopped walnuts, brown sugar, ghee, and cinnamon. Mix together the crumble and set aside.
  • Make the coffee cake batter: In a large bowl, mix together the almond flour, coconut flour, arrowroot, and baking powder. In a separate bowl, whisk together the eggs, ghee and vanilla extract. Pour the wet ingredients into the dry and mix. Add the shredded zucchini and mix again until combined.
  • Pour half of the batter into your prepared baking pan. Spread the batter using a spatula or wooden spoon. Make sure to get an even layer that reaches the edges of the pan. Next, sprinkle the filling over the top and spread evenly across the pan. Add the remaining batter on top and spread carefully and evenly. Top with the crumble topping.
  • Bake for 35-37mins, until a toothpick comes out clean. Let cool for at least 10 minutes before serving. Mix together the optional glaze and drizzle on top when ready to serve. Enjoy!
