Ingredients:
- 1 ½ cups All-Purpose Flour (for crust)
- ¼ cup Light Brown Sugar, packed
- ¼ teaspoon Fine Sea Salt (for crust)
- ½ cup Unsalted Butter, very cold, cut into small cubes
- 3 Large Eggs, lightly beaten
- 1 (14-ounce) can Sweetened Condensed Milk
- 1 cup Pure Pumpkin Purée (Not pumpkin pie filling)
- 1 teaspoon Vanilla Extract
- 1 teaspoon Ground Cinnamon
- ½ teaspoon Ground Ginger
- ¼ teaspoon Ground Nutmeg
- 1 tablespoon All-Purpose Flour (for filling)
- ½ teaspoon Fine Sea Salt (for filling)
- ¾ cup Butterscotch Chips
Instructions:
- Prep the Oven and Pan: Preheat oven to 350°F (175°C). Line the 9x13 inch baking pan with parchment paper, leaving an overhang on the two long sides to act as handles. Lightly grease any exposed pan edges.
- Combine Dry Ingredients: In a medium bowl, whisk together the 1 ½ cups flour, brown sugar, and ¼ tsp salt. Cut in the cold, cubed butter using a pastry blender or fingertips until the mixture resembles coarse, pea-sized crumbs. Do not overmix.
- Press the dough mixture firmly and evenly into the bottom of the prepared pan. Use the flat bottom of a measuring cup to ensure a compact, smooth layer. Bake the crust for 12–15 minutes, or until the edges are just set and lightly golden. Remove from the oven but keep the oven running.
- In a separate large bowl, whisk together the eggs, sweetened condensed milk, pure pumpkin purée, and vanilla extract until smooth. Gently fold in the cinnamon, ginger, nutmeg, ½ tsp salt, and the 1 tablespoon of flour. Mix only until just combined.
- Gently stir the ¾ cup of butterscotch chips into the filling mixture. Carefully pour the pumpkin mixture over the hot, par-baked crust. Return the pan to the oven and bake for 30–35 minutes, or until the edges are set and the center has a slight wobble.
- Remove the bars from the oven and place them on a wire rack to cool completely at room temperature for about 1 hour. Transfer the cooled bars (still in the pan) to the refrigerator and chill for a minimum of 2 hours, or until completely firm. This step is vital for clean, tidy cuts.
- Use the parchment paper overhangs to lift the chilled block out of the pan. Place on a cutting board and slice into 15 even squares using a sharp knife dipped in hot water between cuts.
