Broiled Peanut Frosting

Combine peanut butter, light cream, and brown sugar in a medium bowl, stirring until smooth and fully incorporated.

Fold in coconut and chopped peanuts if using, distributing them evenly throughout the mixture.

Spread the peanut frosting evenly over a cake or cooled baked good on an oven-safe surface.

Position an oven rack 4-6 inches from the broiler element and preheat the broiler to high heat.

Place the frosted cake under the broiler and watch carefully, broiling for 2-3 minutes until the frosting is bubbling and lightly golden brown.

Remove from the broiler immediately and let cool for 2-3 minutes before serving, as the frosting will be extremely hot.
