I found this recipe on allrecipes.com this morning and they turned out so good! =) They are called "To Die For Blueberry Muffins" ... and just let me say the name fits! Jeff and Lydia really liked them! We'll be making these again for sure!
1. Preheat oven to 400*. Put muffin liners in pan (or grease pan).
2. Combine vegetable oil, egg and milk in a bowl. Add 1 1/2 cups flour, 3/4 cup sugar, salt and baking powder. Mix together. Fold in blueberries. Fill muffin cups and sprinkle crumb topping on top.
3. For crumb topping: Mix together 1/2 cup sugar, 1/3 cup flour, 1/4 cup butter and 1 1/2 tsp. cinnamon. Mix with fork and sprinkle over muffins before baking.
4. Bake for 20-25 minutes until done.
