Ingredients

  • 1/4 cup butter, melted
  • 1/3 cup firmly packed brown sugar
  • 3 tablespoons half and half milk
  • 1/3 cup chopped nuts
  • 3/4 cup shredded or flaked coconut

Instructions

  1. Combine all ingredients in a saucepan.
  2. Bring to a boil and cook until the frosting becomes bubbly.
  3. Spread evenly over the cake.

Tips & Substitutions

For a richer flavor, consider using unsalted butter instead of regular butter. If you want a healthier version, you can substitute coconut with unsweetened applesauce or omit it altogether. If you prefer a different nut, walnuts or pecans work well too. Make sure to stir constantly while cooking to prevent burning, especially as the frosting thickens.

Serving Suggestions

This frosting pairs beautifully with a moist oatmeal cake or even a classic vanilla cake. For a delightful presentation, top the frosted cake with extra chopped nuts or a sprinkle of coconut. Serve it alongside a cup of coffee or tea for a perfect afternoon treat. Consider serving with a side of Easy Spinach Dip for a balanced dessert spread.

Storage & Reheating

Store any leftover frosting in an airtight container in the refrigerator for up to a week. When ready to use, allow it to come to room temperature before spreading it on the cake. You can also gently reheat it in a saucepan over low heat, adding a splash of half and half if it has thickened too much.

Frequently Asked Questions

Can I make this frosting ahead of time?

Yes, you can prepare this frosting up to 3 days in advance. Just store it in the refrigerator in an airtight container. When you're ready to use it, let it come to room temperature, and if needed, reheat it gently while stirring until it's spreadable.

What can I use instead of half and half milk?

If you don't have half and half, you can substitute it with equal parts of whole milk and heavy cream to achieve a similar creaminess. Alternatively, for a lighter option, use skim milk mixed with a bit of butter to replicate the fat content.

How do I know when the frosting is done cooking?

The frosting is ready when it becomes bubbly and thickens slightly. You can test its consistency by drizzling a small amount over a cool surface; if it holds its shape without running, it's done. Be careful not to overcook, as it can become too thick.
