How to Make Guinness Chocolate Cake with Irish Buttercream

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Grease and flour your 9-inch round baking pans.

Step 2: Prepare the Dry Ingredients

In a large mixing bowl:
Whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt until well combined.

Step 3: Mix the Wet Ingredients

In another bowl:
Combine sour cream, vegetable oil, eggs, vanilla extract, and Guinness beer. Mix until smooth.

Step 4: Combine Mixtures

Slowly add the wet mixture to the dry ingredients:
Stir gently until just combined. Be careful not to overmix; some lumps are okay.

Step 5: Bake the Cake

Divide the batter evenly between prepared pans:
Bake in preheated oven for about 40 minutes or until a toothpick inserted in the center comes out clean.

Step 6: Cool the Cakes

Remove from oven and let them cool in pans for about 10 minutes:
Transfer cakes to cooling racks to cool completely before frosting.

Step 7: Make the Irish Buttercream

In a mixing bowl:
Beat softened butter until smooth. Gradually add powdered sugar while mixing.
Pour in Irish cream and beat until fluffy. If needed, melt chopped chocolate with heavy cream in a small saucepan over low heat; allow it to cool slightly before adding it to the buttercream mixture.

Step 8: Frosting the Cake

Once cakes are completely cooled:
Spread an even layer of buttercream on top of one cake layer. Place the second layer on top and frost the top and sides of the entire cake as desired.

Step 9: Decorate

Finish with sprinkles or chocolate curls on top for an extra touch of sweetness.

Common Mistakes to Avoid

Baking can be tricky, especially with a rich dessert like Guinness Chocolate Cake with Irish Buttercream. Here are some common mistakes to watch for.

  • Using cold ingredients: Make sure all your ingredients, particularly eggs and sour cream, are at room temperature. This helps the batter blend smoothly.
  • Overmixing the batter: When combining the wet and dry ingredients, mix just until combined. Overmixing can lead to a dense cake instead of a light one.
  • Not measuring accurately: Use a kitchen scale or proper measuring cups to ensure you get accurate ingredient amounts. Incorrect measurements can affect texture and flavor.
  • Skipping the cooling time: Allow the cake to cool completely before frosting it with Irish buttercream. Frosting a warm cake can cause the icing to melt away.
  • Using low-quality cocoa: Invest in good quality unsweetened cocoa powder for the best flavor in your Guinness Chocolate Cake. A higher quality cocoa will enhance the chocolate taste.
