Coffee Cake Muffins

Preheat the oven to 375 degrees F (190 degrees C). Line a 12-cup muffin tin with paper liners.

Mix then sift flour, sugar, cinnamon, baking powder, and salt together in a large bowl.

Mix milk, butter, eggs, and vanilla extract together in a large bowl with an electric mixer. Carefully fold in flour until combined but slightly lumpy. Pour batter into the prepared muffin tins, leaving a little room at the top for muffins to rise.

Combine flour, melted butter, sugar, brown sugar, pumpkin pie spice, and salt for the topping in a bowl; mix until crumbly. Add a generous amount on top of each muffin.

Bake in the preheated oven until tops spring back when lightly pressed, 20 to 30 minutes. Cool in the tin for 5 minutes. Transfer to a wire rack to cool completely.
