If there is crumb in the name for crumb muffins, you better believe there should be a lot of crumb on top!
FOR THE CRUMB TOPPING
FOR THE MUFFIN
- 1 1/4 cup cake flour
- 1/2 cup granulated sugar
- 1/4 tsp baking soda
- 1/4 tsp salt
- 6 tbsp unsalted butter, cut into 6 pieces, softened but still cool
- 1 large egg
- 1 egg yolk
- 1 tsp vanilla extract
- 1/3 cup buttermilk or 1/3 cup plain yogurt
Preheat oven to 325 degrees. Line muffin pan with baking cups or prepare panettone baking cups by spraying them lightly with cooking spray.
In a medium bowl, whisk together sugars, cinnamon, and salt. Pour the butter over top and using a wooden spoon, mix until incorporated. Then 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 at low speed, add 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 extract and buttermilk and mix until all has been incorporated and batter is light and fluffy.
Using a 1/4 cup measuring cup (**see NOTES below), 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. (Note: 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.)
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.
You’ll need to use deeper/taller than normal baking cups for this otherwise the crumb topping will fall off. If you use normal baking cups, use less batter then add the crumb topping.
