#139 Bakery-style berry muffins

Every year Mia asks me to make these for her birthday. Since we're not allowed to share homemade treats at her school, she takes them to her Girl Scout meeting. Everybody always goes crazy for them and asks for the recipe. It calls for frozen mixed berries and Mia always requests blueberries and raspberries. These are a cinch to whip up and I love that they're a frosting-free birthday tradition!
