I'm a bit late on these as I made them for a party we went to just before Christmas. They turned out really cute and festive, in part I think because I made the icing look swirled like peppermint so that people would know what they were getting into. They were a bit heavy to me overall. I found the cake to be a little dense and the icing to be thick and very peppermint-y. I would definitely still make them again, just with a few changes. I found this recipe through Baked By Rachel which is an awesome blog, I follow on Twitter and Pinterest. Her pictures are amazing and get me every time.
On with the cupcakes!
4 Tbsp unsalted butter, softened
1/2 Cup granulated sugar
1/2 tsp vanilla paste
2 egg whites
1/4 tsp salt
3/4 tsp baking powder
1/4 Cup skim milk (Or whatever you have!)
3/4 Cup Cake and Pastry flour (AP should work too, sifted)
3 Tbsp unsalted butter, softened
1.5 Cups icing sugar
1/2 tsp peppermint extract (or less if you choose)
4-6 Tbsp water
Preheat oven to 350°F. Line a mini muffin/cupcake pan with 20 liners. Thats how many I got out the recipe, you could get plus or minus a couple
Cream together butter and sugar to start the cupcakes. Add vanilla paste and egg whites. Process until the batter is no longer lumpy and add remaining dry ingredients, with the milk last.
Mix until ingredients are just combined. Divide among liners, roughly 3/4 full, I found a mini (ice cream type) scoop works well for this size of cupcake to keep them all pretty even.
Bake for 13-15 minutes (in my non convection oven) on the middle rack or until a toothpick comes out clean. Let cool in tins for a few minutes before transferring to a wire rack to cool completely.
While cupcakes are cooking, beat together softened butter, icing sugar and peppermint extract. Add 2-3 tbsp of the water, to help keep the icing sugar from going everywhere when you start mixing.
Slowly add more water until a thick but still spreadable consistency is reached, depending how you plan to frost your cupcakes.
Cover well until ready to use.
Wait until cooled completely to frost. I used a small round tip and created the stripes in my frosting by placing red food colouring in stripes upward from the tip of my bag, so the icing would dye as it came out.
I would recommend a disposable bag for this as it will more than likely stain your bag.
