Ingredients
Equipment
Method
- Preheat your oven to 350°F (175°C). Grease an 8-inch round cake pan and line the bottom with parchment paper. In a food processor, blend the pistachios until finely ground.
- In a large bowl, combine the ground pistachios and powdered sugar. Add the eggs, vanilla extract, baking powder, and salt. Mix until smooth.
- Pour the batter into the prepared cake pan. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean. Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
- In a small saucepan, heat the heavy cream until it just starts to simmer. Remove from heat, then add chocolate chips and butter. Stir until melted and smooth.
- Once the cake is cool, pour the ganache over the top, letting it drip down the sides. Let set before slicing.
