    Wow! These were amazing!! Made them for my husband’s b-day and he LOVED them. Just two little things with the recipe. Recipe says:
    1. Add salt to the cupcakes…no measurement for salt in the ingredients list
    2. Add milk to the icing…no measurement for milk in the ingredients list

    I added 1/4 tsp salt for the first and ~ 2 Tbsp for the second and they turned out wonderful.
