Ingredients
For the cupcakes:
2 cups flour
1-1/2 tsp baking powder
1/2 tsp baking soda
1/4 tsp salt
1/2 cup unsalted butter, at room temperature
1/2 cup sugar
1/2 cup dark brown sugar
3 large eggs
1-1/2 tsp vanilla
1 tsp butter flavoring
1/2 cup buttermilk
1/2 cup cream soda
For the butterscotch ganache:
1 11-oz package butterscotch chips
3/4 cup heavy cream
For the buttercream frosting:
1/2 cup unsalted butter, at room temperature
1/3 cup butterscotch ganache
1 tsp vanilla
1 tsp butter flavoring
1/8 tsp salt
1 lb powdered sugar
Splash of cream (as needed)
Preparation
Making the Cupcakes:
- Preheat oven to 350 degrees and line cupcake tins with paper liners.
- In a large bowl, whisk together flour, baking soda, baking powder, and salt. Set aside.
- In the bowl of an electric mixer (or a large bowl and a hand mixer), cream together butter and sugars until light and fluffly, about 2-3 minutes.
- Beat in eggs one at a time, mixing until well incorporates (about 1 minute), scraping down the sides of the bowl between each addition.
- Add in vanilla and butter flavoring, mix for about 1 minute.
- Combine buttermilk and cream soda in a small bowl (or measuring cup for ease).
- Alternate adding the flour and the buttermilk mixture with the mixer on low, starting and ending with the flour.
- Fill cupcake liners 3/4 full (I would fill 2/3 full) and bake for 15-17 minutes, or until cake tester comes out clean. Cool completely on wire racks.
Making the Butterscotch Ganache:
- Melt the butterscotch chips and heavy cream together using a double boiler until completely smooth (or in a heat safe bowl in the microwave). Cool to room temperature to allow the ganache to slightly thicken.
- Set 1/3 cup or mixture aside and fill a plastic squeeze bottle with the remaining ganache. Insert tip into each cooled cupcake about halfway down, squeeze gently filling until the ganache starts to slightly overflow.
Making the Frosting:
- Cream butter in the bowl of an electric mixer until light and fluffy. Add remaining 1/3 cup of ganache, vanilla, butter flavoring, and salt and mix until well combined. Beat in powdered sugar and allow it to come together for about 2 minutes. Add cream a tablespoon at a time until desired consistency is reached.
- Pipe frosting onto cupcakes with a large tip and drizzle leftover butterscotch ganache over each.
