In a bowl combine the oats, flour, brown sugar, cinnamon, salt, and pecans. Stir in the melted butter until the mixture is wet and slightly clumpy. Set aside.
Pumpkin Blueberry Muffins
Preheat oven to 400° F. and line a standard 12 cup muffin pan with parchment paper liners or spray with cooking spray.
In a large bowl whisk together the dry ingredients, minus the blueberries. In a smaller bowl whisk together the wet ingredients. Pour the wet ingredients in with the dry and stir together just until combined.
Add the blueberries to the batter and carefully fold them in. Divide the batter evenly into the prepared muffin pan. Top the muffins with the oat streusel, pressing it lightly into the batter.
Bake on the middle rack of the oven for 15-18 minutes or until a toothpick inserted in the center comes out with a few crumbs attached. Let the muffins cool in the pan for 5 minutes before removing them onto a wire cooling rack.
Notes
If using frozen blueberries, add them to the muffin batter frozen. Do not defrost.
