Ingredients:
- 1 cup sourdough starter (unfed)
- 3/4 cup unsalted butter, melted
- 1 cup brown sugar
- 1/2 cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 2 1/4 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 2 cups chocolate chips or chunks
- 1 cup walnuts, chopped (optional)
Directions:
-
Preheat the Oven: Set your oven to 350°F (175°C) and line a 9×13 inch baking pan with parchment paper.
-
Mix the Wet Ingredients: In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until fully combined. Add in the eggs and vanilla extract, and stir until smooth. Mix in the sourdough starter until everything is incorporated.
-
Combine the Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry mixture into the wet ingredients, stirring until just combined.
-
Add the Fun Stuff: Gently fold in the chocolate chips (or chunks) and chopped walnuts, if using.
-
Bake: Spread the batter evenly into the prepared pan. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Keep an eye on the edges, as they may brown a little faster than the center.
-
Cool and Slice: Let the bars cool in the pan for about 10 minutes before lifting them out using the parchment paper. Cut into squares and enjoy!
Pro Tip: These bars can sometimes take a little longer to bake than the recipe suggests, depending on your oven, so be sure to check the edges for that perfect golden brown before taking them out. They’ll be a hit every time!
