How to Make St. Patrick’s Day Chocolate Mint Cake
Step 1: Prepare the Cake Pans
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans to prevent sticking.
Step 2: Make the Cake Batter
In a large mixing bowl, combine:
1. Flour
2. Sugar
3. Cocoa powder
4. Baking powder
5. Baking soda
6. Salt
Add:
7. Eggs
8. Milk
9. Oil
10. Vanilla extract
Beat with an electric mixer for 2 minutes on medium speed until well blended. Then stir in the boiling water until smooth; note that the batter will be thin.
Step 3: Bake the Cakes
Pour the batter evenly into the prepared cake pans. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Allow the cakes to cool in the pans for 10 minutes before removing them from the pans to cool completely on a wire rack.
Step 4: Prepare the Mint Frosting
In a large mixing bowl, beat the softened butter until creamy. Gradually add powdered sugar followed by peppermint extract. Mix until you achieve a smooth consistency; adjust with heavy cream as necessary for spreadability.
Step 5: Assemble the Cake
Place one layer of cake on a serving plate. Spread a generous layer of mint frosting on top before placing the second layer over it. Frost the top and sides of the cake with remaining mint frosting.
Step 6: Make the Chocolate Ganache
In a small saucepan over low heat, melt chopped bittersweet chocolate while stirring in heavy cream until smooth. Remove from heat and let it cool slightly to thicken.
Step 7: Glaze the Cake
Pour chocolate ganache over the frosted cake, allowing it to drip down sides for an attractive finish. Let it set for a few minutes before slicing.

- Overmixing the Batter: Mix just until combined; overmixing can lead to a dense cake. Gentle mixing helps keep the cake light and fluffy.
