🥘Ingredient Notes

You'll need the following ingredients for this delicious cake:

• Semi-sweet Bakers chocolate. Do not use chocolate chips.
• Unsalted butter. I use unsalted butter so I can control the salt in my recipes. Salted butter vary in terms of how much salt they contain.
• Guinness beer. I use Guinness stout beer (draft).
• Sour cream. Adds creaminess and moisture to this recipe.

And for the Chocolate Irish Cream frosting, you'll need:

Chocolate Baileys Frosting ingredients:

• Shortening. I use Crisco but you can use another brand of vegetable shortening.
• Dream Whip powder. Lends a really creamy texture to this frosting!
• Irish Cream. I use Bailey's Irish Cream Liqueur.
• Milk. I use 1% milk.

🔪How to Make Guinness Chocolate Cake with Baileys Frosting

Prep: Preheat oven to 350 degrees F/176 degrees C

Combine flour, sugar, salt, and baking soda in a large mixing bowl or the bowl of a stand mixer.

Combine chocolate and butter in a microwave-safe medium bowl and melt in the microwave at ½ power for about 2 minutes, remove and stir after 1 minute, then in 30-second intervals until melted

Alternatively, you can melt it in a large saucepan over low heat

Gradually add the chocolate mixture to the dry ingredients and beat well.

Add in beer and beat for 20 more seconds

Blend in the remaining wet ingredients (eggs, sour cream, and vanilla), and beat 30 seconds at medium speed.

Grease a 9X13 pan (I use Cake Release) or you can use non-stick cooking spray to prevent it from sticking.

Pour wet batter into greased pan.

Bake in a preheated oven at 350 degrees/176 degrees C for 40-50 minutes or until cake tester comes out clean. Cool on wire rack.

Meanwhile make the Irish Cream Frosting:

Add the shortening and mix while slowly adding powdered sugar.

Then add the cocoa, Irish Cream, and vanilla extract.

Then add the milk, a little at a time, until you get a smooth texture and the right consistency. * If you want a thicker consistency, use less milk.

Once the cake is cool, you can frost the cooled cake right in the pan, using a butter knife to make swirls

Add rainbow sprinkles (non- pareils or jimmies.)

Slice into 12 pieces with a serrated knife
