Pumpkin Muffin Bars

Preheat oven to 350ºF. Line the bottom and sides of a 9×9 baking dish with foil, leaving an overhang on all sides.

Cream the butter and sugar on medium speed of an electric mixer. Once smooth, add the egg, vanilla, and pumpkin puree and mix until combined. Add the dry ingredients and mix on low speed until just combined. Don’t overmix.

Fold in the raisins. Spread batter evenly into the baking dish. Bake until edges begin to pull away from sides of pan and a toothpick inserted in center comes out with just a few moist crumbs attached, 35 to 40 minutes. Cool completely in the pan before cutting.
