Chocolate Guinness Cupcakes

The full ingredients list and instructions are found in the printable recipe card at the end of this post. I highly recommend reading the blog post all the way through so that you don’t miss any tips or substitution suggestions and to ensure that you have all the ingredients and equipment required as well as understand the steps and timings involved. Photos are for illustrative purposes only.

These fun cupcakes are simple to make and will be the perfect addition to your St. Patrick’s Day Dessert table!

The chocolate and Guinness cupcakes are made by using a box of Devil’s Food Cake mix and the famous dark Irish stout.

They’re then topped with a swirl Bailey’s Irish Cream frosting that has been tinted ever so lightly green.

The finishing touch on these St. Patrick’s Day cupcakes are shamrock sprinkles and a little touch of gold leaf.

Think of these cupcakes as the gold at the end of a rainbow!

Ingredients & Equipment Used In This Recipe

You may have some baking ingredients in your kitchen already – the full list with measurements is found in the recipe card.

For your convenience, any specialized or notable ingredients and equipment needed to make these cupcakes have been listed below and linked to Amazon or other stores if available online.

Cupcakes & Frosting Ingredients

  • Box of Devil’s Food Cake Mix – but we’re switching the usual water that is used in the mix, with Guinness!
  • Guinnessor another brand of dark Irish stout.
  • Powdered Sugar – known as Icing Sugar in the UK.
  • Pure Vanilla Extract – always buy the best you can afford, it really does make a difference.
  • Bailey’s Irish Cream Liqueurthis is added to the frosting instead of regular cream.

Decorating Ingredients

Cupcake Decorating Equipment

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog! I try to give American, imperial, and metric measurements in my recipes. You can mix cup measurements with weighted measurements, but never imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).

Cupcake Recipe Tips

  • These cupcakes are made using a box of cake mix – but we’re replacing the water with Guinness!
  • You can use green or gold or St. Patricks’ Day-themed cupcake liners to bake your cupcakes in if you like or stick to regular white ones.
  • Use an ice cream scoop to equally divide the cupcake mixture between the cupcake liners. Fill them about three-quarters full.
  • The cupcakes should be ready in around 20 minutes – test their doneness by inserting a toothpick into the cakes. It should come out clean when the cupcakes are cooked through. Bake for an extra 2 minutes and check again.
  • Cool the cupcakes in the pan for 5 minutes before transferring them to a wire rack to cool completely before frosting.

Cupcake Frosting Tips

  • When making the frosting you want the end result to be creamy, smooth, and for it to hold a stiff peak. You may have to adjust the amount of powdered sugar and cream (in this recipe it is Bailey’s Irish Cream Liqueur!) slightly to achieve the consistency you need.
  • The frosting is colored using food coloring. Remember that you can always add more color, but not take it away. Add a little to start with and add more to get the shade required.
  • Food coloring is available in various forms. You’re most likely to find liquid coloring in your grocery store, and other types of coloring like gels, pastes, and powders in more specialised cake decorating shops. The cheapest option is liquids, but they can alter the consistency of your frosting and cake batter, so I prefer to use pastes or gels which don’t. A little goes a long way with food coloring gels and you can usually get a much deeper shade than you would with liquids.
  • You will need a large piping bag fitted with an open star tip such as a Wilton #1M
  • If you feel like you are going to be making a lot of cakes and cupcakes in your future, I think it is worth investing in a set of piping tips so that you know you always have the right ones on hand for a recipe.
  • Do not overfill the piping bag with frosting, and make sure you squeeze the frosting down the bag to expel any air bubbles.
  • If you are not confident with your piping skills you can practice on some parchment paper first and scoop the frosting back into the bag to use on the cupcakes.
  • To transfer gold leaf to your cupcakes, use a clean, unused paintbrush, to pick up the gold leaf from the backing paper and kind of drape it on. Gold leaf can be tricky to work with, so peel the paper back a little at a time and work patiently!
