Frosting Recipe

Although my default preference is generally cream cheese frosting, I needed a mint frosting for a mint chocolate chip cake for my sister's birthday celebration. This was light, fluffy and not cloyingly sweet. I'll definitely use it again. I also used this site's recipes for frosting tints. Turns out, 10 drops of blue and 10 drops of green makes a convincing mint chip color.

Ingredients
1 1/2 cups granulated sugar
1/4 cup all-purpose flour
3 tablespoons cornstarch
1/4 teaspoon salt
1 1/2 cups milk
2 teaspoons pure vanilla extract
24 tablespoons (3 sticks) butter, cut into 24 pieces and softened at room temperature

In a medium bowl, combine the sugar, flour, cornstarch and salt. Slowly whisk in the milk until the mixture is smooth. Cook the mixture over medium heat, whisking constantly, until the mixture boils and is thick enough that it starts to become difficult to easily whisk. This could take anywhere between 5-10 minutes, depending on your stove, heat, etc. It should bubble quite a bit at the end (be careful of the splatters) and thicken considerably.

Transfer the mixture to a clean bowl and cool to room temperature – this is extremely important! If it is even slightly warm, the frosting won’t beat up properly. I put mine in the bowl of my Kitchenaid stand mixer with the paddle attachment and let it run on low speed for a while to assist in the cooling. I did drop it in the fridge for 5-10 minutes, but make sure you have it at room temp before you start. If you try to proceed with the rest of the recipe and the mixture is too cold, the butter won’t absorb into the frosting like it should.

Once the frosting is completely cooled to room temperature (it should have no hint of warmth at all!), beat the mixture with the vanilla on low speed until it is well combined, about 30 seconds (a stand mixer will work best for this). Add the butter, one piece at a time, and beat the frosting until all the butter has been incorporated fully, about 2 minutes. Increase the speed to medium-high and let the mixer work it’s magic. Beat the frosting for five minutes, until it is light and fluffy.

 

Variations:

Mint Chip: Rather than vanilla, add 2.5tsp mint extract instead. Then add finely chopped dark chocolate before frosting the cake.

Chocolate Version: Add 1/4 cup cocoa powder to the sugar, flour, cornstarch, salt mixture in the first step. Once the frosting has been mixed for five minutes and is light and fluffy, mix in 3 ounces of semisweet chocolate that has been melted and completely cooled to room temperature
