Store-bought box mixes make it easy to bake up a batch of muffins, but the flavor can sometimes be a little underwhelming. Luckily, there are lots of easy ways to upgrade your box muffin mix! For a blast of fruit flavor, stir your favorite fresh or frozen berries into the batter. If you want to add a little crunch or texture to your muffins, try stirring in chopped nuts or toasted coconut flakes. You can also play around with flavors by incorporating vanilla extract, cinnamon, pumpkin purée, and so much more!
