Perfect Cupcake Frosting and Filling

5 from 298 votes
This light, creamy, dreamy flour-based frosting is THE perfect cupcake frosting and filling!
Prep Time 15 minutes
Cooling Time 30 minutes
Total Time 45 minutes
Servings12 1/4 cup servings

Ingredients

  • 3 tablespoons all-purpose flour
  • ½ cup milk whole milk is best, but I've used non-fat when it's all I have and it's actually fine
  • ½ cup real butter slightly softened (I prefer salted, but you can use also unsalted and add salt to taste)
  • ½ cup granulated sugar 
  • 1 teaspoon vanilla extract or other flavor if you wish

Instructions

  • Whisk together the flour and the milk (you could also run it through the blender first). Heat in a small sauce pan on medium heat.
  • Whisk continuously until it starts to thicken. Let it cook, while stirring with a rubber spatula, until you can start to see the bottom of the pan. Continue to cook until mixture has the consistency of thick pudding or paste.
  • Put mixture in the fridge and let it cool completely; it's fine if it stays in there long enough to get chilly, you just don't want it warm at all. As it's cooling, feel free to stir it occasionally to speed up the process and keep it from forming a crust on top. You can also do this quickly in the freezer, just keep an eye on it so it doesn't freeze.
  • Using the whisk attachment on an electric stand mixer, beat the butter and the sugar for a minute or two until well combined and fluffy. While beating, add in the thickened milk mixture, any food coloring, and the flavor extracts. Beat to combine and then scrape down the sides. Mixture will separate and look messy, keep beating!  Continue beating until mixture comes together and is light and fluffy, about 7-8 minutes, but time varies.  Take a sample of frosting between your fingers; frosting is done when light and fluffy and sugar granules are dissolved.

Notes

  • Store finished frosting or frosted desserts, covered tightly, in the refrigerator. Allow to come to temperature for 20-30 minutes before serving.
  • If using frosting within a few hours of making the frosting or within a few hours of frosting cakes or cupcakes, simply cover and store at room temperature until time to serve.
  • This frosting can be soft or even melt if it gets too warm. If needed, pop the whole mixing bowl in the fridge for 15 minutes and rewhip to help it hold its shape.
  • Don't leave frosted desserts sitting in the sun or in a warm environment for too long with this frosting or it may soften/melt!
  • Use real butter, and a good name-brand. Cheap butter does weird things.
  • If you beat for the 6-8 minutes and the mixture still looks strange, beat longer and at a higher speed if you can. It should come together, but it takes a little patience!
  • I personally think this frosting is best eaten fresh.  You can store for a few hours at room temperature, or try storing in the fridge overnight, letting it come to room temperature on its own, and then re-beating to fluff.  If you want to frost cupcakes or a cake the day before, refrigerate and just let come to room temp after.
  • Add extracts to your hearts content; lemon and almond are both wonderful! Food coloring is also okay.
  • The white sugar can be exchanged for brown. Try 1/2 white 1/2 brown for a warm caramel flavor.
  • Do not try to make other substitutions or additions. Sour cream, fruit purees etc. can do disastrous things.  Some people have had amazing success, just experiment at your own risk.  
  • If trying to decide whether or not to double it- double it.  Chances are you’ll want more.  It’s a rather small batch, but on purpose.  
  • 1 batch will not look like much, but it can spread on (just with a knife, a normal amount) 24 cupcakes.  If you want to pipe it thick, definitely double it.
  • Looking for Chocolate? This Chocolate Frosting isn’t exactly the same, but very similar!
