Sweet and fluffy chocolate cakes paired together with a creamy peanut butter frosting – these whoopie pies are a delight for cake enthusiasts. The love affair with peanut butter and chocolate continues this week with these special Chocolate Peanut Butter Whoopie Pies.
Have you had one before? Nothing says American baking to me quite like a whoopie pie. They are a unique cake-like cookie that gives you the excuse to eat two cookies and a healthy dose of frosting in one delicious treat – what’s not to love?
I’m really looking forward to eating plenty of authentic whoopie pies on our next trip to the USA. They are not common here in Australia at all – but that’s ok because now you can just make them at home. Once I decided to tackle whoopie pies this week, I just knew they had to be chocolate and peanut butter.
I made them twice to make sure they were just right. I added a little cream cheese to the frosting to cut through the sweetness and add a bit of zing. I promise these are really easy and totally worth turning on your oven for!
Chocolate Whoopie Pies with Peanut Butter Frosting
Makes 24 cookies/12 whoopie pies
Chocolate Whoopie Pies
115 grams (1 stick) unsalted butter, softened
1/2 cup brown sugar
1/4 cup caster sugar
1 large egg
1 teaspoon vanilla extract
1 and 1/2 cups plain flour
1/2 cup cocoa
1/2 teaspoon baking powder
1/4 teaspoon baking soda
1/2 cup + 3 tablespoons buttermilk
Peanut Butter Frosting
3 cups icing sugar
3 tablespoons unsalted butter, softened
3 tablespoons milk
1/4 cup + 1 tablespoon smooth peanut butter
1 tablespoon cream cheese, softened
Line two oven trays with baking paper. In a large mixing bowl, beat the butter and sugar with an electric mixer until pale and creamy. Add the egg and vanilla extract and beat until combined. Sift in the flour, cocoa, baking powder and baking soda. Add half the buttermilk and gently stir with a wooden spoon, before adding the rest of the buttermilk. When the mixture is combined, it will be quite wet – similar to cake batter.
Transfer the batter into an airtight container and pop into the freezer for 30 minutes. This will help firm up the mixture so you can easily roll spoonfuls of the batter into balls – just like you would for cookies. They will be a bit sticky but rolling them in your hands will help achieve a nice smooth finish.
Preheat the oven to 180 degrees (360 F). Place the cookies onto the prepared trays and when the oven is ready, pop them in for 8-10 minutes. Leave them to cool for a few minutes and then transfer the cookies onto a wire rack. While they are cooling, you can make the peanut butter frosting.
In a large mixing bowl, add the icing sugar, butter and milk and gently beat using an electric mixer. Add the peanut butter and the cream cheese and beat until smooth and creamy. Pipe the icing onto one whoopie pie before placing another on top. Continue until all whoopie pies are complete.
