Why You’ll Love This Recipe

Easy pumpkin recipe — No rolling out a traditional pie crust. The shortbread crust is pressed into the pan, and both the pumpkin filling and crumble topping are mixed by hand. These bars hold up well, so they’re an excellent make-ahead dessert that won’t get soggy.

Traditional flavors — The filling tastes like classic pumpkin pie: creamy texture, warming pumpkin pie spice, and familiar structure. It’s everything you expect from pumpkin pie, reimagined as bars.

Elevated pumpkin pie — The brown sugar oat streusel gives extra caramel-like warmth and crunchy texture, enhancing the cozy spice notes.

Ingredients

• Light brown sugar — used in both the shortbread base and the crumble topping. Dark brown sugar can be substituted for a deeper caramel note.
• Pumpkin puree — use pure pumpkin puree (not pumpkin pie filling, which already contains sugar and spices).
• Sweetened condensed milk — one 14 oz can adds sweetness and structure to the pumpkin layer.
• Pumpkin pie spice — a convenient blend of warm spices for pumpkin desserts; use your preferred blend or make a small mixture from cinnamon, nutmeg, ginger, and cloves.
• Rolled oats — old-fashioned rolled oats give texture to the streusel topping.

See the recipe card below for the full ingredient list with exact quantities.

Substitutions and Variations

• Use dark brown sugar instead of light brown for a richer flavor.
• Fold ¼ cup chopped walnuts or pecans into the crumble topping for added crunch.
• Swap quick-cooking oats for rolled oats if that’s what you have on hand.
• For a different base, try a graham cracker crust instead of shortbread.
• Omit the streusel topping and reduce bake time slightly; finish with cinnamon whipped cream.
• Make half the recipe in a 9×5″ loaf pan or double it for a 9×13″ pan.

How to Make This Recipe

One: Cream the butter and brown sugar until light and fluffy.

Two: Add the flour and mix on low until combined into a slightly sticky shortbread dough.

Three: Scatter pieces of dough across a lined 8×8″ pan and press with your fingertips into an even layer. Par-bake the crust.

Four: Whisk together pumpkin puree, sweetened condensed milk, eggs, vanilla, and pumpkin pie spice until smooth.

Hot tip! Add dollops of shortbread dough around the pan and press them together to form an even crust — this helps reach the corners cleanly.

Five: Pour the pumpkin filling over the cooled par-baked crust and return to the oven to bake.

Six: Mix the crumble topping ingredients (flour, brown sugar, oats, melted butter, and spices) with a fork until crumbly.

Seven: Remove the partially baked bars and gently sprinkle the crumble to cover the top and sides. Finish baking until the filling is set at the edges with a slight jiggle in the center.

Eight: Cool the bars on a wire rack for one hour, then chill in the fridge for at least three hours until fully set. Slice into 16 pieces and serve chilled.

Expert Tips

• Line the pan with parchment slings so you can lift the cooled bars out easily for cleaner slicing.
• Use your fingertips in quick pushing motions to press dough into corners and sides for an even crust.
• Bake until the edges are set and the center has only a slight jiggle — this ensures a creamy but firm pumpkin layer after chilling.
• Chill the bars completely (uncovered in the fridge) before cutting to avoid cracking and to get clean slices.
• Slice with a serrated knife to saw gently through the streusel, then push down and pull the knife straight out for neat pieces.
