The other day we were going to have company drop by, and I realized I had nothing to serve with coffee for our guests. Being a recipe blogger, I didn’t want to just go buy something from the bakery in case they asked me for the recipe, which they usually do. That would be a little embarrassing to tell them oh, I didn’t make these the bakery did. Being recipe bloggers friends and family expect something homemade.
