Brown Sugar Instant Oatmeal Muffins

Preheat oven to 400 degrees F (200 degrees C). Grease 12 muffin cups.

Combine 3 tablespoons flour, brown sugar, and cinnamon in a small bowl. Use a pastry blender or two knives to cut in the butter until the mixture resembles coarse crumbs. Reserve.

Combine 1 3/4 cup flour, white sugar, baking powder, salt, and the instant oatmeal in a large bowl. Make a well in the center of the flour mixture; pour in the egg, milk, and oil. Stir just until moistened. Spoon batter into prepared muffin cups, filling each 2/3 full. Evenly sprinkle streusel topping over muffins.

Bake in preheated oven until toothpick inserted in center of muffin comes out clean, about 15 minutes. Cool on wire rack for 5 minutes before serving.
