I made these little darlins a couple weeks ago. I was inspired by the Mini Reese's Peanut Butter Cup Cupcake recipe from Hoosier Homemade. She used a mix though, and I wanted to make my cupcakes from scratch, so used this recipe from For the Love of Cooking. Very simple, and they turned out great, despite my concern since there was no butter in the recipe.
Then I used the frosting recipe as shown in the original post on Hoosier Homemade. That frosting... OMG! So very yummy!
