Description
Festive chocolate cupcakes made with Guinness, topped with vibrant green frosting for a delightful St. Patrick’s Day treat.
Ingredients
- 1 cup (240 ml) Guinness stout (room temperature)
- 6 tbsp (85 g) unsalted butter
- 3/4 cup (150 g) granulated sugar
- 2/3 cup (135 g) light brown sugar, packed
- 1 large egg, room temperature
- 1/2 cup (120 g) sour cream or Greek yogurt
- 1 tsp vanilla extract
- 1 cup (125 g) all-purpose flour
- 1/2 cup (45 g) unsweetened cocoa powder, sifted
- 1 tsp baking soda
- 1/2 tsp baking powder
- 1/4 tsp fine salt
- For the frosting: 1 cup (225 g) unsalted butter, softened or 8 oz (225 g) cream cheese
- 3–4 cups (360–480 g) powdered sugar, sifted
- 1–2 tbsp Irish cream liqueur (optional) or 2–3 tbsp milk
- A drop of green gel food coloring
- Pinch of salt
- Optional decorations: green sprinkles, edible gold dust, mini shamrock candies
Instructions
- Preheat the oven to 350°F (175°C). Line a 12-cup muffin tin with liners.
- In a small saucepan, combine the Guinness and butter over medium heat until the butter melts.
- In a large bowl, whisk together flour, cocoa, baking soda, baking powder, and salt. Set aside.
- In the bowl of a mixer, beat the sugars with the egg until combined. Add sour cream and vanilla, mixing until smooth.
- Slowly pour the Guinness-butter mixture into the wet ingredients, whisking to combine.
- Fold the dry ingredients into the wet mixture just until incorporated.
- Divide the batter evenly among the liners (about 3/4 full). Bake for 18–22 minutes until a toothpick inserted comes out with a few moist crumbs.
- Let cupcakes cool for 5–10 minutes, then transfer to a wire rack to cool completely.
- For the frosting, beat softened butter (or cream cheese) until creamy. Gradually add powdered sugar and Irish cream or milk until piping consistency is reached. Add green gel coloring and mix until evenly colored.
- Pipe or spread frosting on cooled cupcakes and garnish with sprinkles or a shamrock candy.
Notes
These cupcakes freeze well un-frosted and can be decorated the day of serving for optimal freshness.
