Notes
One: Pumpkin Streusel Muffins
When making the batter, omit the semi-sweet chocolate chips. Mix together 1/4 cup of flour, 1/4 cup of brown sugar, and 1 teaspoon of ground cinnamon. Cut in 2 1/2 tablespoons of cold butter until crumbly. Sprinkle about one tablespoon of the streusel over each cup of batter. Dust with powdered sugar after they cool, if desired.
Two: Pumpkin Banana Muffins
When preparing the batter, use 1/2 cup of pumpkin puree and 1/2 cup of ripe, mashed bananas. Then, follow the recipe as directed. You can add the chocolate chips or leave them out if you prefer.
Three: Storage
Store the muffins in an airtight container on the countertop for up to 4 days. The muffins can be stored in the freezer in a freezer bag for up to 3 months if you prefer to store them for longer.Recipe adapted from a Pumpkin Chocolate Chip Muffins recipe from my mother-in-law.
