Step 1

Heat the oven to 375 degrees. Line a standard 12-cup muffin tin with liners.

Step 2

Prepare the crumb mixture: In a medium bowl, whisk together the flour, brown sugar, cinnamon and salt. Add the butter, and stir to combine.

Step 3

Prepare the muffins: In a separate medium bowl, whisk together the flour, baking powder, salt and baking soda. Add the cranberries and pecans, and gently toss to combine.

Step 4

In a small bowl, mix together the sour cream and the milk. In a large bowl, with an electric mixer, beat the butter and sugar until fluffy, about 3 minutes. Beat in the eggs, one at a time.

Step 5

Fold the flour mixture into the butter mixture. Fold in the sour cream mixture. Divide the batter evenly between the muffin cups. Squeeze the crumb mixture to create clumps of varying size, and sprinkle evenly over the tops. (It’s OK if some of the crumb mixture lands on the tray.)

Step 6

Bake the muffins until they are puffed and set, and a toothpick inserted into the center comes out clean, 26 to 30 minutes. Let cool in the pan for 10 minutes, then transfer to a rack to cool completely.
