This recipe makes 12 caramel apple cupcakes. The cake is made with flour, baking powder, baking soda, salt, cinnamon, butter, sugar, eggs, vanilla, buttermilk, and chopped apples. The batter is scooped into muffin tins and baked for 15-18 minutes until a toothpick comes out clean. The buttercream frosting is made by mixing butter, vanilla, caramel syrup, and powdered sugar. The frosting is then used to frost the cooled cupcakes.
