What Kind of Guinness Should I Use?

Stick with the classic: Guinness Draught. It’s smooth, malty, and just bitter enough to bring out the richness in the chocolate. Avoid the Foreign Extra Stout unless you want a much bolder and more bitter cupcake.

Ingredients for the Guinness Chocolate Cupcakes

Guinness Draught: The star ingredient that deepens the cocoa notes and keeps the cupcake ultra-moist.

Unsweetened Cocoa Powder: Adds a rich, bittersweet chocolate flavor that pairs beautifully with the stout.

All-Purpose Flour: Provides the structure to hold all that deliciousness together.

Granulated Sugar: Sweetens the deal and balances the bitterness of the beer and cocoa.

Baking Soda: Helps the cupcakes rise, especially when reacting with the acidic Guinness.

Salt: Enhances the chocolate flavor and rounds out the sweetness.

Eggs: Bind the batter and create a soft, tender crumb.

Sour Cream: Adds tang and moisture—key for soft cupcakes.

Vanilla Extract: Just a splash to boost the overall flavor profile.

Butter: Melted and mixed into the beer for a rich base that blends smoothly into the batter.

Frosting (Optional but Highly Recommended): A creamy Irish cream or chocolate buttercream frosting takes these to the next level.

How To Make the Guinness Chocolate Cupcakes

Step 1: Prep Your Ingredients and Tools

Start by preheating your oven to 350°F (175°C). Line a muffin tin with cupcake liners and set it aside. This is also a good time to measure out your ingredients—things move quickly once the wet and dry are combined.

Step 2: Heat Guinness and Butter

In a small saucepan over medium heat, combine the Guinness Draught and unsalted butter. Stir occasionally until the butter melts completely. Remove from heat and whisk in the cocoa powder until smooth and velvety. Let this mixture cool slightly.

Step 3: Mix the Dry Ingredients

In a separate bowl, whisk together the flour, sugar, baking soda, and salt. This will ensure your dry ingredients are evenly distributed.

Step 4: Combine Wet Ingredients

In a large mixing bowl, beat the eggs, sour cream, and vanilla extract together until fully combined and creamy.

Step 5: Bring It All Together

Slowly pour the slightly cooled Guinness mixture into the egg mixture while stirring. Once blended, add in your dry ingredients. Mix until just combined—don’t overmix or your cupcakes will turn out dense.

Step 6: Bake

Divide the batter evenly into the cupcake liners, filling each about two-thirds full. Bake for 17 to 20 minutes, or until a toothpick inserted in the center comes out clean. Let them cool in the pan for 5 minutes before transferring to a wire rack.

Step 7: Frost and Decorate

Once the cupcakes are completely cool, frost with your choice of Irish cream buttercream or chocolate frosting. Swirl high and proud, then sprinkle with cocoa powder or chocolate shavings if desired.

How to Serve and Store These Guinness Chocolate Cupcakes

These cupcakes are best served at room temperature to allow the full richness of the Guinness chocolate flavor and creamy frosting to shine. They pair beautifully with a cup of strong coffee or a small pour of Irish cream for an extra indulgent treat.

If you’re hosting, display them on a tiered dessert stand for a stunning presentation. They’re perfect for St. Patrick’s Day gatherings, adult birthday parties, or cozy winter nights.

To store, place the frosted cupcakes in an airtight container and keep them in the refrigerator for up to 4 days. Let them sit out for about 20 minutes before serving. Unfrosted cupcakes can be frozen for up to 2 months—just thaw and frost when you’re ready to enjoy.

Frequently Asked Questions

How much Guinness can I taste in the cupcakes?

The Guinness adds a subtle depth to the chocolate rather than an overpowering beer flavor. It enhances the richness without tasting boozy.

Can I use a different type of beer?

You can, but darker stouts or porters work best. Lighter beers won’t give the same depth of flavor and may make the batter too thin.

Is the alcohol still in the cupcakes after baking?

Most of the alcohol bakes out in the oven, leaving behind just the rich malty flavor. They are generally safe for all ages, though they’re a hit at adult gatherings.

What frosting goes best with these cupcakes?

An Irish cream buttercream or classic chocolate frosting complements the cupcakes perfectly. You can also try espresso or salted caramel buttercream for a unique twist.

Can I make these cupcakes gluten-free?

Yes! Substitute with a good 1:1 gluten-free flour blend. Just ensure your Guinness (or alternative stout) is gluten-free as well.

Can I make this recipe into a cake?

Absolutely. Pour the batter into a greased 9-inch round cake pan and increase the baking time to about 35 minutes. Check doneness with a toothpick.
