  • Make the topping. Cut the butter into the flour in a medium mixing bowl, using two knives or a pastry blender, until it resembles small peas. Stir in the sugar and cinnamon. Equally distribute the topping on top of the muffin batter.

  • Bake. Bake in preheated oven for 18-23 minutes, until a toothpick inserted in the center comes out clean or with a few moist crumbs. Finished muffins will have golden tops. Remove from oven and allow them to cool on wire rack. Serve warm or room temperature. Muffins will stay fresh two days at room temperature or can be frozen up to one month.

Notes

This recipe makes great jumbo muffins as well: use a tin that hold six jumbo muffins and bake for 25-30 minutes.
If you don't want to make the crumb topping, simply top with coarse sparkling sugar.
