These pumpkin bars are the ultimate fall treat, blending cozy spices, moist texture, and creamy cream cheese frosting into a dessert that's perfect for any autumn occasion. They're easy to make with pantry staples, endlessly customizable, and guaranteed to fill your kitchen with that warm, spiced aroma.
Preheat oven to 350°F (175°C) and lightly grease a 9x13 baking pan. Line with parchment paper, leaving overhang on the sides for easy removal.
In a medium bowl, whisk together flour, baking powder, baking soda, pumpkin pie spice, cinnamon, and salt. Set aside.
In a large bowl, whisk together pumpkin puree, sugar, oil, eggs, and vanilla until smooth and fully combined.
Gradually add dry ingredients to wet ingredients, folding gently with a spatula until just combined. Do not overmix.
Pour batter into prepared pan and spread evenly. Bake for 25-30 minutes, until a toothpick inserted in the center comes out clean. Cool completely in pan on a wire rack.
Beat cream cheese and softened butter with an electric mixer until smooth. Gradually add powdered sugar and vanilla, beating until light and fluffy.
Spread frosting evenly over cooled bars. Cut into 24 squares, wiping the knife clean between cuts for neat edges.
Notes
Use room-temperature eggs and cream cheese for smoother mixing and a lump-free frosting.
Don't overmix the batter once the dry ingredients are added—it can make the bars dense instead of light and tender.
Check the bars at 25 minutes to avoid overbaking; they should look golden and feel slightly springy.
Let the bars cool completely before frosting to prevent the frosting from melting.
Store frosted bars in an airtight container in the refrigerator for up to 5 days, since the cream cheese frosting needs to stay chilled.
To make ahead, freeze unfrosted bars for up to 3 months, wrapped tightly in plastic wrap and placed in a freezer bag. Thaw overnight in the fridge, then frost before serving.
For a chocolate twist, add 1/2 cup chocolate chips to the batter.
Swap the cream cheese frosting for a maple glaze for a different flavor profile.
Use brown sugar instead of granulated sugar for a caramel-like depth of flavor.
To substitute pumpkin pie spice, mix 1/2 tsp cinnamon, 1/4 tsp ginger, 1/8 tsp nutmeg, and 1/8 tsp allspice.
