Preparation Steps
- If you’re using frozen berries, make sure to let them defrost and drain well before adding them to the muffins.
- Preheat oven to 350°F. Line muffin pans with paper baking cups.
- Make the topping by stirring together all topping ingredients with a fork in a medium sized bowl. Set aside.
- Using a hand mixer, mix eggs with electric mixer about 1-2 minutes until thick and frothy. Mix in sugar and oil, beat until creamy. Mix vanilla, vinegar, baking soda, and salt. Mix in sour cream then stir in flour using a wooden spoon. (Batter may be slightly lumpy.) Stir in blueberries.
- Fill muffin cups with about 0.25 cup muffin batter. Sprinkle the crumble evenly over the top of the muffins.
- Bake for 15-22 minutes until a toothpick comes out clean from the center of a muffin. Cool 5 minutes in pan then remove to a rack to cool completely.
- Store in an airtight container for up to 3 days or freeze for up to one month.
Notes
