Let’s get baking! Here’s a detailed, step-by-step guide:

Step 1: Prepare Oven and Batter

Preheat your oven to 350°F (175°C). Line a muffin tin with cupcake liners.

In a large bowl, combine the devil’s food cake mix, vegetable oil, eggs, and 3/4 cup of Baileys Irish Cream. Beat with a hand mixer (or a stand mixer) until well combined.

Step 2: Bake the Cupcakes

Fill the cupcake liners about 2/3 full with batter.

Bake according to the package directions (usually around 18-22 minutes), or until a toothpick inserted into the center of a cupcake comes out clean.

Step 3: Cool the Cupcakes

Let the cupcakes cool in the muffin tin for a few minutes before transferring them to a wire rack to cool completely. It’s important that they are completely cool before frosting.

Step 4: Make the Frosting

While the cupcakes are cooling, make the frosting. In a large bowl, combine the softened butter, half of the powdered sugar (about 2 1/2 cups), 1/2 cup of Baileys Irish Cream, cocoa powder, vanilla extract, and salt.

Using a hand mixer (or a stand mixer), beat until smooth.

Gradually add the remaining powdered sugar and beat until the frosting is fluffy and holds its shape.

Step 5: Frost and Garnish

Once the cupcakes are completely cool, transfer the frosting to a piping bag fitted with a tip of your choice (or simply use a knife or spatula to spread the frosting).

Pipe or spread the frosting onto the cupcakes.

Garnish with chocolate sauce and shaved chocolate.

Serve and enjoy!
