Now THAT I like!My favorite part of a muffin is when streusel is on top ... Here's instructions I found on Allrecipes.com:
Combine 2 tablespoons flour, 5 tablespoons sugar ,and 1/2 teaspoon cinnamon in a small bowl. Cut in 2 tablespoons butter with fork or pastry blender until mixture resembles course crumbs. Sprinkle over batter in muffin cups.
