Ingredients

  • 1 cup butter, softened
  • 4 cups confectioners sugar
  • 1/3 cup dark corn syrup
  • 2 teaspoons rum extract

Instructions

  1. Cream the butter until smooth and fluffy.
  2. Add the confectioners sugar and dark corn syrup alternately to the creamed butter, beating well after each addition.
  3. Beat in the rum extract until fully incorporated.
  4. If necessary, add more confectioners sugar until the frosting reaches the desired spreading consistency.

Tips & Substitutions

For a smoother texture, ensure your butter is at room temperature. If you want to cut the sweetness, consider using half the amount of confectioners sugar and adding a pinch of salt. For a twist, you can substitute the rum extract with vanilla extract for a different flavor profile. This frosting can also be tinted with food coloring to match your dessert theme.

Serving Suggestions

This butter rum frosting is perfect for topping cakes, cupcakes, or cookies. It pairs beautifully with Chocolate Blender Frosting for a layered dessert experience. Consider serving it over a simple vanilla cake or alongside Tropical Glazed Sweet Potatoes for a delightful contrast of flavors. It also works well as a filling for pastries or as a dip for fresh fruit.

Storage & Reheating

Store any leftover butter rum frosting in an airtight container in the refrigerator for up to one week. Before using, let it sit at room temperature for about 30 minutes to soften. If needed, re-whip the frosting to restore its fluffy consistency. You can also freeze it for longer storage, ensuring it's well-sealed to prevent freezer burn.

Frequently Asked Questions

Can I use regular corn syrup instead of dark corn syrup?

Yes, you can use regular corn syrup, but it will alter the flavor slightly, making it less robust. Dark corn syrup adds a richer taste and color to the frosting. If you prefer the flavor of dark corn syrup, try using a mix of half regular and half dark syrup for a balanced taste.

How can I make this frosting less sweet?

To reduce the sweetness of the frosting, you can decrease the amount of confectioners sugar used. Adding a small pinch of salt can also help balance the sweetness. Additionally, incorporating a bit of cream cheese into the frosting will give it a tangy flavor that complements the sweetness.

Can I make this frosting ahead of time?

Absolutely! You can make the butter rum frosting a few days in advance. Just store it in an airtight container in the refrigerator. When you're ready to use it, allow it to come to room temperature and give it a quick whip to restore its fluffy texture before spreading.
