Preheat the oven to 375 degrees and line a muffin pan with liners or grease each muffin cup with nonstick cooking spray.
Ina large bowl, whisk together the milk, brown sugar, melted butter, egg, and vanilla extract.
Add in the flour, baking powder, cinnamon, nutmeg, and salt, and stir just until combined.
Use a tablespoon to spoon the batter into the bottom of each muffin cup.
Top the batter with 1 tablespoon of cranberry sauce.
Add another 1 tablespoon of batter on top of the cranberry sauce. Lightly press the batter down to fill the cupcake liner, being careful not to disturb the sauce.
Prepare the crumble topping by stirring together the flour, brown sugar, cinnamon, and butter until the ingredients begin to clump together
Sprinkle the crumble mixture over the top of each muffin, lightly pressing it into place.
Bake the muffins for 20 to 25 minutes, until the topping is golden brown and a toothpick inserted into the center comes out clean.
Allow the muffins to cool in the pan for a few minutes, then transfer to a wire cooling rack to cool completely.
