Step-by-Step Instructions:
1. Prepare Your Cake Pans and Oven
Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans, then line the bottoms with parchment paper to prevent sticking. This ensures your layered cake releases easily.
2. Combine Dry Ingredients
In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt. Make sure there are no lumps for a smooth cake batter.
3. Add Wet Ingredients (Except Hot Water)
Add the buttermilk, vegetable oil, and eggs to the dry ingredients. Beat with an electric mixer on medium speed for about 2 minutes until just combined and smooth.
4. Incorporate Hot Water
Carefully pour in the hot water and mix on low speed until the batter is smooth and well combined. The batter will be thin, which is normal for this moist layered cake recipe.
5. Bake the Cake Layers
Divide the batter evenly between the two prepared cake pans. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
6. Cool the Cake Layers
Let the cakes cool in their pans on a wire rack for 10-15 minutes. Then, invert them onto the wire rack to cool completely before frosting. This prevents the layered cake from collapsing.
7. Make the Mint Chip Buttercream
In a large bowl, beat the softened butter with an electric mixer until creamy. Gradually add the powdered sugar, alternating with the milk, beating until light and fluffy.
8. Add Mint Flavor and Color
Stir in the mint extract and a few drops of green food coloring, if desired, until you reach your preferred shade. Fold in the chocolate chips by hand.
9. Assemble the Layered Cake
Once the cake layers are completely cool, place one layer on your serving plate or cake stand. Spread about one-third of the mint chip buttercream evenly over the top.
10. Stack and Frost
Carefully place the second cake layer on top. Use the remaining buttercream to frost the top and sides of the entire layered cake. Garnish with extra chocolate chips if you like.
Variation Ideas:
- Double Chocolate Mint: Add a chocolate ganache drizzle over the top before serving.
- White Chocolate Mint: Use white chocolate chips in the frosting instead of semi-sweet.
- Cupcakes: Bake the batter in cupcake liners for individual mint chocolate treats.
- Gluten-Free: Substitute gluten-free all-purpose flour for the regular flour.
Storage Instructions:
Store leftover Dark Chocolate and Mint Chip Layer Cake in an airtight container at room temperature for up to 2-3 days, or in the refrigerator for up to 5 days. If refrigerated, let it sit at room temperature for about 30 minutes before serving for the best texture.
Frequently Asked Questions (FAQ):
Q: Can you prepare the cake layers ahead of time?
A: Yes, you can bake the cake layers a day in advance. Wrap them tightly in plastic wrap and store at room temperature.
Q: What if the buttercream is too thick or too thin?
A: If it’s too thick, add more milk a teaspoon at a time. If it’s too thin, add more powdered sugar a tablespoon at a time until it reaches the desired consistency.
Q: Can you use a different size cake pan?
A: You can use three 6-inch pans for taller layers, but adjust baking time as needed. Avoid pans much larger than 8 inches, or the layers will be too thin.
Q: Why is my cake sinking in the middle?
A: This can happen if the oven door was opened too soon or if the cake is underbaked. Ensure the cake is fully cooked before removing it from the oven.
Q: Can you freeze this layered cake?
A: Yes, you can freeze individual slices or the entire cake (unfrosted or frosted) for up to 2-3 months. Wrap tightly in plastic wrap and then foil. Thaw in the refrigerator overnight.
Q: What kind of cocoa powder is best for this recipe?
A: Unsweetened natural cocoa powder is recommended for its deep chocolate flavor, which perfectly complements the mint in this layered cake recipe.
