Blackberry Filling
Seedless blackberry Jam (I used Smuckers)
Fill an icing bag with the jam, insert the tip into the cupcake about an inch and squirt a little jam inside each cupcake. Do not squeeze too much into the cupcakes or they will kind of explode. You do not need a lot.
Blackberry Buttercream
2 sticks butter, softened
1 tsp vanilla extract
1/2 cup seedless blackberry Jam
pinch of salt
6 cups powdered sugar
2-3 tablespoons milk
Beat butter and vanilla until creamy. Mix in blackberry filling and salt. Add powdered sugar 1 cup at a time, beating until combined. Add milk 1 tablespoon at a time until you reach desired consistency.
