This is our second feature for American Cake Decorating Magazine. I created this recipe for their cocktail e-book that is available exclusively to their VIC members. To get this recipe and many more in this boozy cake collection subscribe here. This refreshing blackberry bourbon cake is based on the popular Mint Julep cocktail. A Mint Julep is traditionally made with bourbon, mint, sugar, and water. The addition of the blackberries is a fun twist to this classic tipple. Just one bite of the delicious cake will take you back to warm summer nights spent sitting on the front porch, watching the fire flies glow in the twilight; the perfect way to relax and say goodnight to a purpose-filled day.
