Ingredients

1 cup Gluten-free oat flour or flour of choice
2 Eggs large
1/2 cups Zucchini peeled and grated
2/3 cup Sugar-free dark chocolate chips about 100-110g of chocolate bar
1/4 cup Coconut oil or avocado oil
1/2 cup Granulated sweetener swerve or coconut sugar
1 teaspoon Baking powder
pinch Sea salt

Frosting:

1 Sweet potato small or half a large
1/2 cup Sugar-free dark chocolate chips or 80-85g of chocolate bar

Instructions

Preheat oven to 350 F and prepare an 8x8 inch pan with parchment paper.
In a large bowl, beat the eggs until light and fluffy (about 1 minute). Whisk in the zucchini and granulated sweetener. Set aside.
In a microwave-safe bowl, gently melt the chocolate and coconut oil together until smooth. Add the chocolate mixture to the zucchini bowl and whisk until incorporated.
Add in the oat flour, baking powder, and salt. Stir until combined.
Transfer the batter to the prepared pan and bake for 24-27 minutes.
Meanwhile, prepare your frosting. Peel and cube your sweet potato. Place the cubes on a microwave-safe plate and cook for 3-4 minutes on high. Transfer the cubes to a food processor or high-speed blender. Blend until pureed. Melt chocolate and add to the sweet potato puree. Continue blending until incorporated.
Once the cake and frosting have both cooled to room temperature, frost cake, and serve.
