Ingredients
Scale
- 1 1/4 cups pumpkin purée, (285g)
- 1/2 cup granulated sugar, (100g)
- 1 1/4 cups brown sugar, (250g), packed
- 1 cup avocado oil, (about 218 g), or other neutral oil
- 4 large eggs
- 1 teaspoon vanilla extract
- 1 cup sourdough discard, (240g)
- 2 cups all-purpose flour, (240g)
- 2 teaspoons ground cinnamon
- 2 1/2 teaspoons pumpkin pie spice
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- 1/2 teaspoon kosher salt
- 8 oz cream cheese, (226g), softened
- 1/2 cup unsalted butter, (113g), softened
- 1 teaspoon vanilla extract
- 1/4 teaspoon fine salt
- 1/2 teaspoon cinnamon or pumpkin pie spice, optional
- 3 to 3 1/4 cups powdered sugar, (360–390g), sifted
- 1–2 teaspoons milk or cream, optional
Instructions
- Preheat oven to 350°F (175°C). Grease or line a 10×15-inch jelly roll pan with parchment.
- In a large bowl, whisk together the pumpkin purée, granulated sugar, brown sugar, oil, eggs, vanilla, and sourdough discard until smooth.
- In a separate bowl, whisk together the flour, cinnamon, pumpkin pie spice, baking powder, baking soda, and salt.
- Add the dry ingredients to the wet ingredients and stir just until combined.
- Pour the batter into the prepared pan and spread into an even layer.
- Bake for 20–25 minutes, or until a toothpick inserted in the center comes out clean. Let the bars cool completely before frosting.
- In a large bowl, beat the softened cream cheese and butter together until smooth and fluffy, about 2–3 minutes.
- Add the vanilla, salt, and optional cinnamon or pumpkin pie spice. Mix to combine.
- Gradually beat in the powdered sugar, starting with 3 cups and adding up to 3¼ cups for your desired sweetness and consistency. If needed, add a small splash of milk or cream to loosen the frosting.
- Spread the frosting evenly over the cooled pumpkin bars. For neater slices, chill for 15–20 minutes before cutting.
- Cut into slices. This recipe makes about 20-24 bars, depending on how you cut them.
Notes
- Store any leftover bars in an airtight container in the refrigerator.
- Feel free to adjust the spices to your taste.
- These bars can also be frozen for later enjoyment.
