- 1/3 cup granulated sugar
- 1/3 cup brown sugar
- 3/4 teaspoon ground cinnamon
- 1/4 teaspoon salt
- 8 tablespoons unsalted butter (melted)
- 1 3/4 cups cake flour
- 1 1/4 cup cake flour
- 1/2 cup granulated sugar
- 1/4 teaspoon baking soda
- 1/4 teaspoon salt
- 6 tablespoons unsalted butter (cut into pieces, softened but still cool)
- 1 egg
- 1 egg yolk
- 1 teaspoon vanilla extract
- 1/3 cup plain yogurt
- Preheat oven to 325 degrees. Line muffin pan with baking cups or prepare larger baking cups on a sheet pan. *see note
- In a medium bowl, whisk together the sugar, brown sugar, cinnamon, and salt. Pour in the melted butter and using a wooden spoon, mix until incorporated. Add the cake flour and mix until mixture resembles a thick and cohesive dough. Set aside.
- In the bowl of a stand mixer fitted with the paddle attachment, mix flour, sugar, baking soda, and salt on low speed to combine. With mixer on low speed, add the butter one piece at a time; continue beating until mixture resembles moist crumbs, with no visible butter chunks remaining, 1 to 2 minutes.
- Add the egg, egg yolk, vanilla, and yogurt, and mix until all has been incorporated and batter is light and fluffy.
- Using a ¼ cup measuring cup, divide up batter into prepared muffin pan. Then, sprinkle a generous amount of the crumb topping on top, using your fingers to pinch the dough into a crumbly mixture, if not already. Do not press the crumb topping into the batter. Just let it sit on top.
- Bake for 20 minutes or until crumbs are golden and a toothpick inserted into the middle comes out clean.
- Let muffins cool for 5 minutes before transferring them to a wire rack to cool completely.
- Store in an airtight container for up to 2 days.
*If you use regular sized muffin cups you will need to put less batter in each cup in order for the topping to be contained within the cup. I used taller baking cups for these in order to pile on the topping!
*I did stick my muffins under the broiler at about the 15 minute baking mark so the tops would get nice and brown. If you do this, make sure to watch it carefully. You do not have to do the broiler step and can omit it completely.
