I decided to double my blueberry muffin recipe. One batch for now and freeze the other batch for later. You can cook any muffins according to their instructions. After they are done baking, place on a cookie sheet and freeze 1-2 hours. Then place in a gallon ziplock bag and place back in the freezer. When you are ready to eat them, just set them out to thaw. If you like them warm, pop them back in microwave for 5-10 seconds.
I used the following blueberry recipe.
