Ingredients
For the Cake
- 1 ¾ cups all-purpose flour
- 2 cups granulated sugar
- ¾ cup unsweetened cocoa powder
- 1 ½ teaspoons baking powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt
- 2 large eggs
- 1 cup whole milk
- ½ cup vegetable oil
- 2 teaspoons vanilla extract
- 1 cup boiling water

For the Ganache

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 the following dry ingredients:
1. Flour
2. Sugar
3. Cocoa powder
4. Baking powder
5. Baking soda
6. Salt
Add in the wet ingredients:
1. Eggs
2. Milk
3. Oil
4. Vanilla
Beat these ingredients with an electric mixer on medium speed for about two minutes until well combined. Finally, stir in the boiling water until smooth (the batter will be thin).
Step 3: Bake the Cakes
Pour the batter evenly into prepared cake pans. Bake in preheated oven for 30-35 minutes or until a toothpick inserted in the center comes out clean. Allow cakes to cool in pans for ten minutes before transferring them to a wire rack to cool completely.
Step 4: Prepare the Mint Frosting
In another large mixing bowl, beat softened butter until creamy and smooth. Gradually add powdered sugar while mixing, then incorporate peppermint extract until fully combined. Adjust with heavy cream as needed for spreading consistency.
Step 5: Assemble the Cake
Place one layer of cake on a serving plate and spread a generous amount of mint frosting on top. Add the second layer of cake on top and frost both the top and sides with remaining mint frosting.
Step 6: Make the Chocolate Ganache
In a small saucepan over low heat, melt chopped bittersweet chocolate until smooth. Stir in heavy cream carefully until well combined then remove from heat; let it cool slightly to thicken.
Step 7: Glaze the Cake
Pour chocolate ganache over frosted cake allowing it to drip down the sides beautifully. Let set for a few minutes before slicing into portions.
Step 8: Serve and Enjoy
Slice your St. Patrick’s Day Chocolate Mint Cake and serve it up with joy during your celebrations!
