frequently asked questions
1. Can I make these cupcakes ahead of time?
Yes! Bake the cupcakes a day ahead, then frost and decorate just before serving.
2. What if I don’t have peppermint extract?
You can use mint extract instead, but it has a stronger, slightly different flavor than peppermint.
3. How do I get a fluffier buttercream?
Whip the frosting for an extra minute to incorporate more air, making it light and fluffy!
4. Can I use homemade vanilla cupcake batter instead of cake mix?
Absolutely! Just replace the cake mix with your favorite homemade vanilla cupcake recipe.
5. How do I prevent my frosting from being too soft?
If the frosting is too soft, add more powdered sugar (1 tablespoon at a time) to thicken it.
