If you're into pumpkin spice, you have to try this super easy sourdough discard pumpkin bake. These bars are dense, rich, and seriously delicious—basically fall in dessert form. Bonus: your whole house will smell amazing while they bake!

This pumpkin bake is a great way to use up leftover pumpkin puree. It's great for when you have just a little extra discard that you don't want to toss, too. Not the healthiest, but a treat for Fall and Winter. Please make sure you are using pure pumpkin and not pumpkin pie filling.

Equipment:
- Baking dish: 8x8 or 9x7
- a spatula
- a mixing bowl
- a small microwave safe bowl
- parchment paper
- measuring cups
- measuring spoons
Ingredients:
- ¾ Cups pumpkin puree, see note
- 12 Tablespoons (1.5 sticks) butter
- ⅓ Cup sourdough starter, unfed
- 1 Cup coconut sugar
- 1 egg
- 1 teaspoon vanilla extract
- 1 Cup dark chocolate- set aside ¼ cup to drizzle over the top
- 1.5 cups all purpose flour
- ¾ teaspoons salt
- 1 teaspoon baking powder
- 1.5-2 teaspoons pumpkin pie spice. This depends on how strong of a flavor you want. I ended up using 2 teaspoon but I will probably use closer to 1.5 teaspoon next time.
- 1 teaspoon coconut oil for melting chocolate
Instructions:
- First gather your equipment and ingredients
- Preheat your oven to 375℉
- Then we are going to start by melting the butter in a microwave safe bowl. Once that it melted we are going to add in your pureed pumpkin, sourdough starter, coconut sugar, vanilla extract, and egg.
- Mix everything together until it's well combined.
- On the top, add the flour, baking powder, salt, and pumpkin pie spice. Carefully mix your dry ingredients a little bit before mixing them into the wet mixture. We don't need to dirty two bowls. We're efficient.
- Once the wet and dry ingredients are mixed, it's time to fold in your chocolate chips. Remember to set aside ¼ Cup of chocolate to melt and drizze over the top.
- Line your baking pan with parchment paper and carefully add in the batter.
- Once it is spread as evenly as you can get it, pop it in the oven for about 35 minutes.
- It will be gone when a toothpick can be inserted and comes out clean. You will be able to tell that the top is getting a little more solid and darker.
- Allow it to cool for twenty minutes. While it's cooling, take about a teaspoon of coconut oil and put it in a microwave safe bowl with your ¼ cup of chocolate. Cook just 20 seconds at a time and stir frequently. It's done once it is fully melted. If it's too dry you can add a bit more coconut oil.
- Once the cake is cool you can drizzle it over the top with a spoon. You could also put it in a baggy and cut a tiny hole in the corner.
- Enjoy!
Notes
- Make sure that you use pure pumpkin and not pumpkin pie filling.
