Broiled Peanut Butter Frosting
This vintage Broiled Peanut Butter Frosting recipe delivers a sweet, nutty topping with a caramelized crunch. Made with brown sugar, butter, peanut butter, and chopped peanuts, the frosting is briefly broiled to create a glossy, bubbly finish that hardens slightly as it cools. A mid-century favorite, this frosting was often paired with yellow or spice cakes and became popular in American home baking for its quick preparation and irresistible texture. It’s perfect for those who enjoy a rich, nutty sweetness with a hint of crunch.

Ingredients
  

  • 2 tbsp peanut butter
  • 1 tbsp butter
  • ½ cup brown sugar
  • 1 tbsp cream
  • ½ cup salted peanuts (chopped)

Instructions
 

Step 1: Make the Frosting Base

  • In a small bowl, combine peanut butter, butter, brown sugar, and cream. Mix until smooth and creamy.

Step 2: Spread the Frosting

  • Spread the frosting evenly over a baked cake, cupcakes, or desired dessert.

Step 3: Add Crunch

  • Sprinkle chopped peanuts over the top.

Step 4: Broil the Frosting

  • Place the cake under the broiler about 5 inches from the heat source. Broil for 2–3 minutes until the topping is bubbly and slightly caramelized.

Step 5: Cool and Serve

  • Allow the frosting to set slightly before slicing and serving.

Tips

  • Use crunchy peanut butter to add extra texture.
  • Substitute half-and-half or evaporated milk if cream isn’t available.
  • Add a splash of vanilla for a rounder flavor.
  • Spread frosting on warm cake for easier broiling and slight soaking.
  • Watch closely under the broiler, sugars brown quickly.
  • Line the pan edges with foil to protect cake from burning while topping broils.
  • Add a pinch of salt if using unsalted peanuts/peanut butter to enhance flavor.
  • Mix in shredded coconut for a broiled “German-chocolate-style” variation.
  • For less sweetness, reduce brown sugar slightly and add more chopped nuts.
  • Let stand a few minutes after broiling to allow topping to set and become crackly.
