Step-by-Step Instructions
Now for the fun part! Let’s get these delicious brownies baking!
Preheat the Oven: Preheat your oven to 350°F (175°C). Trust me; that warm air will work wonders for your brownies!
Melt the Butter: In a medium saucepan, melt 1/2 cup unsalted butter over low heat until it’s all just melted. Your kitchen will smell amazing, and it’s time to take that butter off the heat, don’t let it brown!
Mix in the Sugars and Eggs: Stir in 1 cup sugar, 2 large eggs, and 1 teaspoon vanilla extract into the melted butter. Mix until everything is well combined and the mixture is glossy.
Add the Sourdough Discard: Now, toss in 1 cup sourdough discard and mix well. The batter is already starting to look incredible!
Combine Dry Ingredients: In a separate bowl, whisk together 1/2 cup all-purpose flour, 1/3 cup cocoa powder, and 1/4 teaspoon salt. This is the secret to keeping those brownies fluffy!
Mix it All Together: Gradually add the dry ingredients to the wet mixture, stirring until just combined. You want to avoid overmixing; lumps are okay!
Fold in the Chocolate Chips: If you’re feeling extra chocolaty, fold in 1/2 cup chocolate chips at this stage. Trust me; they’re a game changer!
Pour and Spread: Pour the batter into the prepared 9×9 inch baking pan and spread it evenly. It’s like a big ol’ chocolate hug in there!
Bake: Pop those lovelies into the oven for 25-30 minutes, or until a toothpick inserted into the center comes out mostly clean. A few crumbs are perfectly fine, better than overdone brownies!
Cool Down: Allow them to cool before cutting into squares and serving. Just letting them rest for a bit helps set that fudgy texture!
