These cupcakes are soft, light and fluffy with a pronounced banana sweetness. I filled each cupcake with my signature salted caramel, which I must confess is the perfect texture……gooey and caramelly excellent to fill cupcakes with. Then came the piece de resistance……the butter popcorn frosting. You will want to eat this frosting all on its own cause it’s that good, but now’s a good time to practice self-control!
