How to Make Sourdough Pumpkin Bars with Cinnamon Cream Cheese Frosting
- Preheat your oven to 350°F (175°C). Prepare a 9×13-inch baking dish by greasing it or lining it with parchment paper.
- Mix wet ingredients: In a large bowl, combine pumpkin puree, sourdough discard, sugar, vegetable oil, eggs, and vanilla extract. Stir until smooth and well-combined.
- Add dry ingredients: In a separate bowl, whisk together flour, baking soda, baking powder, cinnamon, cloves, and salt. Slowly incorporate the dry mixture into the wet ingredients, mixing just until combined. Avoid overmixing.
- Bake: Pour the batter evenly into the prepared baking dish. Bake for 25–30 minutes or until a toothpick inserted into the center comes out clean. Let the bars cool completely before frosting.
- Prepare frosting: In a mixing bowl, beat together softened cream cheese and butter until smooth. Add powdered sugar, ground cinnamon, and vanilla extract. Beat until fluffy and creamy.
- Frost and serve: Once the bars are fully cooled, spread the cinnamon cream cheese frosting evenly across the top. Slice into squares or bars and serve.

Frequently Asked Questions
Can I use sourdough discard straight from the fridge?
Yes, absolutely. Cold sourdough discard works just fine in this recipe. There’s no need to bring it to room temperature since it’s being used for flavor and texture, not for leavening.
How do I store leftover sourdough pumpkin bars?
Store the frosted bars in an airtight container in the refrigerator for up to 5 days. For best results, let them sit at room temperature for 10–15 minutes before serving to soften the frosting.
Can I freeze these bars?
Yes, these bars freeze beautifully. Freeze unfrosted bars wrapped individually in plastic wrap and then in a freezer-safe bag for up to 2 months. Thaw overnight in the fridge and frost before serving.
