It also falls into the “not too sweet” category of frosting for those who prefer that. I know there’s plenty of you out there because you already love many of the other “not too sweet frostings” that I’ve shared on this blog:

Whipped Cream Cream Cheese Frosting
Chocolate Whipped Cream Cream Cheese Frosting
Whipped Vanilla Frosting
Whipped Chocolate Frosting

They are the frostings that get the most rave reviews. You know you’ve got a hit on your hands when people single out the frosting on a cake or a cupcake and ask you, “What kind of frosting is this? It’s so good!”

They all have the same thing in common. They are not teeth aching, gritty, sugar coma sweet. That’s the kind of frosting that I can live without, the kind I scrape off and leave on the plate.

This, on the other hand, is the frosting you leave ON the cake. This is the frosting that you might want piled even a little higher on your cupcake.

This is the mint version of the Whipped Vanilla Frosting that is part of the White Zucchini Cake post. That vanilla frosting truly deserves its own post, but until then, this is the Whipped Peppermint Frosting version.

It’s a cooked flour frosting. I know. If you’ve never tried it, it sounds kind of weird.

Basically, you’re going to make a thick white sauce. It’s almost like a bechamel, but there’s no butter in it, just flour and milk. (The butter comes later…)

When you cook those two together, it will smell like you’re cooking a creamy wheat cereal. You start with a slurry adding just a bit of milk at a time and stir constantly so that you don’t end up with lumps.

Bring it to a boil and let it cook for a full minute before removing it from the heat to cool. Placing a piece of plastic wrap right on the surface will help prevent a skin from forming on the top.

I usually make this part in advance and once it’s just slightly warm, stash it in the refrigerator until I’m ready for it either that same day, or the next.

Once it’s completely chilled, you can see that it has solidified into a thick, but spoonable mass. It doesn’t have to be this cold, it just needs to be cool, but the timing of having it ready in the refrigerator works well for me. And, it only takes a few minutes to get that step out of the way.

Now, let’s talk about the temperature of your butter. We want soft, almost room temperature butter. It should still be a little cool. Thirty minutes at room temperature should do it. You should be able to press your finger into it and leave an indentation. I like to think of it as bendable.

What we don’t want is butter that is so soft and warm that it can’t hold it’s shape. You shouldn’t be able to flatten your whole stick of butter with one light push of a spatula. If you can do that, your butter is too soft.

You’ll beat your butter, sugar, salt and flavorings for a few minutes until light and fluffy.

Then, you’ll begin to add your cooked flour mixture, one spoonful at a time, beating well after each addition. I usually give it about 15 seconds of beating after each spoonful is added.

The mixture may curdle and look broken (see photo above.) Keep beating until it’s light and fluffy. This should happen no later than about 2-3 minutes after your last addition of the cooked flour mixture.

If it’s not coming together at that point, and by the way, this has happened to me more than once, your mixture might be too cold to emulsify, a possible issue should you make your flour portion really cold as I do. This is an easy fix.

Just take a small spoonful (about a Tablespoon) out of the curdled mixture and heat it just until it melts. Add that little bit of melted frosting back to the main bowl and whip away. You should see the mixture change from curdled to fluffy and you’ll be good to go.

I chose to top these Dark Chocolate Cupcakes with this Whipped Peppermint Frosting. I can’t think of a better friend to mint than chocolate, don’t you agree?

When my husband bit into his cupcake, he said it was like eating a giant thin mint cookie. He also thought the frosting tasted “light.” I think that’s a high compliment, considering we’re talking about buttercream :)

And then there’s the whole green thing. Yes, I added a few drops of green food dye. I’m not a huge fan of dye, but I know having a food blog is largely a visual endeavor and green=mint, so I added a few drops just to hit the flavor home.

Of course, St. Patrick’s Day is also right around the corner, the day everything goes green, including the river that flows through Chicago. (Going green on that day sometimes seems like anything but being green) :/

Yeah, it’s not easy being green. Ah, but it is easy to make a deliciously Whipped Peppermint Frosting…

Whipped Peppermint Frosting

Yield: makes enough to generously pipe 12 cupcakes

Whipped Peppermint Frosting

Ingredients

  • 3 Tablespoons all purpose flour
  • 1 cup milk (I used whole milk)
  • 1 cup (2 sticks) unsalted butter, cool room temperature
  • 1 cup granulated white sugar
  • 1 teaspoon vanilla extract
  • 1 teaspoon peppermint extract (make sure this is peppermint, not just mint)
  • 1/4 teaspoon salt
  • green food dye, optional

Instructions

  1. Make the cooked flour portion of your buttercream. Place the 3 Tablespoons of flour into a small sauce pan and place over medium low heat. Whisk in 1/4 cup of the milk insuring that all flour gets incorporated and you don't have lumps. You're creating a slurry.
  2. Slowly whisk in the remaining milk. Adding small amounts of liquid at a time will help you avoid any lump issues.
  3. Continue to whisk constantly over medium heat and continue whisking for 1 minute after the mixture begins to boil. Remove from heat. Transfer to a shallow dish to allow for faster cooling. Once it cools off a little, press a piece of plastic wrap on the surface to deter a skin from forming.
  4. Allow to cool at room temperature until it's just barely warm, then transfer to the refrigerator. It will become a soft solid mixture once it is cooled.
  5. With a mixer, beat the two sticks of butter, sugar, vanilla, peppermint and salt until well combined and fluffy. I like to beat this for 2-3 minutes.
  6. Slowly add spoonfuls of the cooled cooked flour mixture into the butter, beating well after each addition. After all of the cooked flour mixture has been added, continue beating the mixture until it is light and fluffy and the sugar is completely dissolved (check by rubbing some frosting between your fingers.) If the mixture looks curdled, it isn't done yet. Just keep mixing it until it all comes together. This shouldn't take longer than about 2-3 minutes after your last addition of the cooked flour.
  7. If your mixture won't get passed the curdled stage, it might be too cold. Take about a Tablespoon of the curdled frosting and put it in a small microwave safe bowl. Heat for 5 seconds or until JUST melted. It should not be hot, just melted. Add back into the bowl with the rest of the frosting and continue beating until whipped and fluffy. Add green food dye, if desired and whip until combined.

Notes

*Frosted items can be stored at room temperature or in the refrigerator. If you opt to refrigerate, allow to come to room temperature before serving for creamiest texture.

*You can see how much frosting I piped onto each cupcake in the photos. Even with that amount, I still had a good 3/4 cup of frosting leftover, so there's enough to pipe pretty generously.

*If you want enough frosting to frost and fill an 8 or 9" layer cake or 24 cupcakes, you'll need to double the recipe.

*Mint extract smells/tastes like spearmint, not peppermint. I made that mistake once. Avoid your frosting tasting like chewing gum and make sure you buy peppermint extract...unless spearmint is truly what you're looking for.

*Peppermint extract can be strong. 1 teaspoon was plenty for me to get a good mint flavor. You can add or reduce the amount to taste.

*This is not a frosting that I make ahead and store in the refrigerator before using. It's really tricky to get it to whip back up to it's wonderful fluffy self after it's solidified in the refrigerator. I opt to pipe it as soon as I make it and then store the frosted cake/cupcake.
