Ready in under 10 minutes, this salty-sweet frosting is perfect for spur-of-the-moment desserts. With it, you can turn a batch of fresh banana muffins into cupcakes, make snack-time sandwiches with graham crackers, or whip up a simple topping for brownies. While honey's a natural match for peanut butter, don't hesitate to try maple syrup or molasses instead; any sticky syrup will doeven homemade caramel, if you happen to have a batch on hand.
