Step-by-step instructions

1. 1

   Preheat the oven to 350 degrees. Combine the flour, baking powder, and baking soda in a small bowl and set aside.

2. 2

   In a separate bowl, cream the butter, sour cream or yogurt, and vanilla. Whisk the egg into the mixture; add the sugar and mix until well combined.

3. 3

   Stir the flour mixture into the butter mixture until just moistened.

4. 4

   For the streusel, combine the brown sugar, flour, cinnamon, salt, and butter in a small bowl. Cut the butter into the sugar and flour until coarse crumbs form. You can also use a food processor for this.

5. 5

   Spoon the batter into buttered and floured jumbo muffin tins, filling about 1/3 of the way. Sprinkle a heaping tablespoon of crumbs (or more for a thicker streusel layer in the middle) on top of the batter. Cover with more batter until 3/4 of the way full and sprinkle streusel crumbs over the top of each muffin. Bake for 15+ minutes, depending on the size of your muffin tins.
