Ingredients

(A printable recipe card is included at the bottom of this post for your convenience.)

• 1/2 cup unsalted butter
• 1 1/2 cups semi-sweet chocolate chips
• 1/2 cup cocoa powder (any kind)
• 2 teaspoons vanilla extract
• 2 large eggs
• 1 egg yolk
• 1 cup sugar
• 1/2 cup brown sugar
• 125 grams sourdough starter discard (measure this on a food scale)
• 1 cup all purpose flour
• 1 teaspoon salt

Instructions for Chocolate Sourdough Brownies

1. Preheat oven to 350 degrees and line a 9 inch square baking pan with parchment paper to form a “sling”.
2. In a microwave safe bowl, melt the butter and chocolate chips. Microwave times will vary based on the voltage of your microwave. I just melted mine for 2 minutes and stirred it with a spoon and it was perfect. Once it is melted and stirred smooth, stir in the cocoa powder and then vanilla. Set aside.

3. In the bowl of a stand mixer, beat the eggs, egg yolk, and sugars until frothy and smooth – about 7-10 minutes.

4. Add the melted and cooled chocolate mixture and sourdough discard to the egg & sugar mixture and mix in the mixer on low until combined.

5. Add the flour and salt to the bowl all at once and stir until just combined. Don’t be alarmed by how thick the batter is. That’s the way it should be!;) Drop it by large spoonfuls into the parchment lined pan and smooth wth a knife so it’s in one nice even layer.
6. Bake at 350 degrees for 35-40 minutes, or until the top is slightly firm to the touch and starting to crack.

How to store sourdough chocolate brownies

Tools Used for this Recipe

I love having a nice 9×9 baking pan. That is very similar to mine. I love how it bakes evenly, and it is so easy to clean!

Parchment paper makes getting the brownies out of the pan so much easier. (Get all the details about baking with parchment here.)
