🥣 How to Make Chocolate Guinness Cake

Step 1: Prepare the Cake Batter

1. Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans (or line with parchment paper).
2. In a large mixing bowl, whisk together flour, sugar, baking soda, baking powder, espresso powder, salt, and cocoa powder.
3. In another bowl, whisk together Guinness beer, buttermilk, melted butter, eggs, and vanilla extract until smooth.
4. Gradually add the wet ingredients to the dry ingredients, whisking until smooth and combined (do not overmix).

Step 2: Bake the Cake

1. Divide the batter evenly between the prepared cake pans.
2. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
3. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.

Step 3: Make the Baileys Buttercream Frosting

1. In a large bowl, beat butter until creamy and fluffy (2 minutes).
2. Gradually add powdered sugar, beating on low until combined.
3. Add Baileys Irish Cream, vanilla extract, and salt. Beat for 2-3 minutes until smooth and fluffy.

Step 4: Assemble & Frost the Cake

1. Place one cake layer on a serving plate. Spread a generous layer of Baileys buttercream over the top.
2. Place the second cake layer on top and frost the entire cake with the remaining buttercream.
3. Smooth the frosting or create decorative swirls with a spatula.
4. Garnish with chocolate shavings, cocoa powder, or a drizzle of Baileys if desired.

🍽 What to Serve with Chocolate Guinness Cake

• A glass of Guinness or Irish coffee ☕🍺
• A scoop of vanilla or chocolate ice cream 🍨
• Whipped cream with a drizzle of Baileys
• Fresh berries for contrast 🍓

💡 Tips for the Best Guinness Cake

✔ Use room-temperature eggs and buttermilk – This helps create a smooth batter.
✔ Sift the cocoa powder and flour – Ensures a light, lump-free cake.
✔ Cool the cake completely before frosting – Warm cake can cause the frosting to melt.
✔ For extra Baileys flavor, brush a little Baileys over the cake layers before frosting!

❄️ How to Store

• Refrigerate: Store in an airtight container in the fridge for up to 5 days.
• Freeze: Wrap slices tightly in plastic wrap and freeze for up to 3 months. Thaw in the fridge overnight before serving.
