Method
- Preheat the oven to 350°F (175°C). Line a 9 inch cake pan with parchment paper.
- In a large mixing bowl, whisk together the eggs, mashed sweet potato, olive oil, maple syrup, and vanilla until smooth and creamy.
- Sift the flour and cacao powder into the bowl. Add baking soda, salt, and espresso powder if using. Gently mix until smooth, avoiding overmixing.
- Pour the batter into the prepared pan and smooth the top evenly.
- Bake for 22 to 25 minutes. The center may look slightly soft but will firm as it cools. Let cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
- To make the frosting, blend avocados, cacao powder, and maple syrup in a mini food processor until smooth and fluffy.
- Once the cake is completely cool, spread frosting evenly over the top. Add shaved dark chocolate or sprinkles if desired. Slice into eight portions and serve.
Notes
This cake stays moist thanks to the sweet potato and olive oil. For best texture, ensure the cake is fully cooled before frosting. Store leftovers in the refrigerator for up to 3 days.
