Prepare the Cake:
- Preheat the Oven: Preheat your oven to 350°F (175°C) and grease and flour an 8-inch round cake pan.
- Mix Dry Ingredients: In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. Set this mixture aside as your dry ingredients.
- Cream Butter and Sugar: In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy. This usually takes about 3-5 minutes.
- Add Eggs and Vanilla: Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract until everything is well combined.
- Combine Wet and Dry Ingredients: Gradually add the dry ingredients to the wet mixture, alternating with the buttermilk. Mix until just combined overmixing can result in a dense cake.
- Pour and Bake: Pour the batter into the prepared cake pan and smooth the top. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean.
- Cool the Cake: Let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.

- Fold in Ingredients: Gently fold in the pistachio paste, powdered sugar, and vanilla extract until well combined. If using gelatin, fold it in at this point.
- Spread Mousse: Once the cake is completely cool, spread the pistachio mousse evenly over the top. Refrigerate for at least 2 hours to set.
Prepare the Chocolate Ganache:
- Heat Cream: In a small saucepan, heat the heavy cream over medium heat until it begins to simmer. Be careful not to let it boil.
- Combine with Chocolate: Remove from heat and pour the hot cream over the chocolate chips in a heatproof bowl. Let it sit for a minute, then stir until smooth and fully combined.
- Cool Ganache: Allow the ganache to cool slightly before pouring it over the chilled pistachio mousse layer. This will create a beautiful glaze.
Assemble and Garnish:
- Garnish: Once the ganache has set slightly, garnish with chopped pistachios and chocolate shavings to add texture and visual appeal.
