- cooking spray
- 1 butternut squash, halved lengthwise and seeded
- water, as needed
- 3/4 cup white sugar
- 3 tablespoons butter
- 1 cup all-purpose flour
- 3/4 cup oats
- 2 1/2 teaspoons baking powder
- 1/2 teaspoon ground cinnamon
- 1/2 teaspoon ground nutmeg
- 1/2 teaspoon ground allspice
- 1/4 teaspoon salt
- 2 eggs
- 1/2 cup milk
- 1 tablespoon sour cream
- 1 teaspoon vanilla extract
- 12 pecan halves
- Preheat oven to 375 degrees F (190 degrees C). Prepare 12 muffin cups with cooking spray or line with paper liners and prepare the liners with cooking spray.
- Put squash into a roasting pan with cut sides down. Pour enough water into pan to fill 1/2-inch deep.
- Roast squash in preheated oven until flesh is easily pierced through with a fork, about 45 minutes. Remove roasting pan and reduce heat to 350 degrees F (175 degrees C).
- Scoop hot squash into a large bowl and mash until no large chunks remain. Stir sugar and butter into the squash.
- Whisk flour, oats, baking powder, cinnamon, nutmeg, allspice, and salt together in a bowl.
- Beat eggs, milk, sour cream, and vanilla extract together in a separate bowl. Stirring constantly, add a spoonful of squash mixture into the egg mixture to temper it before adding egg mixture to the squash mixture; stir.
- Fold flour mixture into the squash mixture until just incorporated; spoon into muffin tins. Top each with a pecan half.
- Bake in the preheated oven until a toothpick inserted into the center comes out clean, 12 to 15 minutes.
