1. Whisk together coffee, espresso powder and cocoa in a small bowl and set aside. Sift together flour, baking soda and baking powder in another small bowl and set aside. Measure out buttermilk and mix with vanilla extract and set aside.

2. In a large bowl cream together butter, sugar and salt. Add eggs, one at a time, beating each egg in thoroughly and scraping the side of the bowl before adding the next egg. Add 1/3 of the flour mixture to the egg mixture and mix until combined. Add 1/2 of the buttermilk and mix until combined. Repeat, ending with the last of the flour mixture. Add the cocoa and coffee mixture and mix until thoroughly combined. Fold in mayonnaise.

3. Divide equally into prepared cupcake liners. Bake for 16-18 mins or until a toothpick inserted comes out clean. Allow to cool thoroughly on wire racks before frosting.

Bailey’s Swiss Meringue Buttercream

5 egg whites
1 cup + 2 tbsp sugar
2 cups of unsalted butter at room temperature
1 tsp pure vanilla
pinch of salt
Bailey’s to taste
1. Fill a saucepan (large enough to fit your mixing bowl just a few inches) with two inches of water. Bring the water to a boil, then reduce heat to med-low so water continues to simmer.

2. In your stand mixer bowl, hand whisk the egg whites and the sugar just until combined. Place over simmering pot and whisk for approx 4 mins until the egg whites are hot (about 150 degrees). The sugar should be dissolved by this time as well. Place bowl on stand mixer and attach the whisk attachment. Whisk on medium speed until whites have increased in volume, are thick and glossy and the outside of the bowl is just slightly warm to the touch (this can take up to 10 minutes!).

3. Remove whisk attachment and replace with paddle attachment. Beat on low-speed until mixture is completely cooled. Increase speed to medium and add butter pieces one at a time. Scrape the bowl and continue to beat until buttercream is glossy, smooth and thick. It may separate at first, but continue beating and it will emulsify. Add vanilla flavouring, a pinch of salt and Bailey’s (to taste) and beat until combined. Use immediately.

Garnish with a chocolate covered espresso bean.
