Roasted chestnut butter frosting is the perfect topping for any Christmas cupcake and there is no open fire needed – although you may find yourself seeking one out as you eat it. The chestnut frosting is not overly nutty, and it has a mild flavor and a smooth buttercream texture.
While peanut butter has it’s fans, chestnut butter is the nut butter of choice for the season. I loved it in the roasted chestnut butter frosting, but it is also great on a piece of toast or in a chestnut butter and cranberry jelly sandwich!
This post covers how to make chestnut butter and then how to make chestnut butter frosting.
To start, you’ll need roasted chestnuts.
I bought my roasted chestnuts at Whole Foods. However, if you want to take the effort to roast chestnuts yourself, Kevin of Closet Cooking has a great post on how to roast chestnuts.
Next, you’ll need to turn those roasted chestnuts into chestnut butter.
Making nut butter is easier than you might think. You just need a food processor. My favorite food processor to use is my mini Cuisinart. Simply grind the roasted chestnuts in your food processor and then add vegetable oil 1 tablespoon at a time and continue to process until it has the consistency of a nut butter. Since roasted chestnuts don’t have much oil in them, you may need to add up to 1/4 cup of vegetable oil per cup of chestnut butter produced.
Now, you can make the roasted chestnut butter frosting.
Roasted Chestnut Butter Frosting
- 1 cup roasted chestnut butter
- 1 cup unsalted butter
- 2 cups powered sugar
- Place the butter and nut butter into a medium bowl and beat with an electric mixer.
- Gradually mix in the sugar.
- Beat for at least 3 minutes for it to get good and fluffy.
What’s the cupcake under the frosting?
The cupcake under that frosting is my mulled wine Christmas cupcake!
