White Wedding Cupcakes

These white wedding cupcakes turn a boxed cake mix into the most amazing vanilla cupcakes you've ever had. They're a close replica to a delicious bakery cake that you would find at a wedding (with the perfect texture!) and are so easy to make! It's become my family's favorite go-to vanilla cake recipe anytime cupcakes are in order.

Pair with cream cheese frosting (my favorite!) or a more pipeable buttercream frosting.
