How to Prepare Easy Sourdough Discard Brownies
Let’s dive into the deliciously simple process of making these Easy Sourdough Discard Brownies! Follow these steps, and I promise you’ll end up with a fudgy, chocolatey treat that will impress everyone.
Preheat and Prepare
First things first, preheat your oven to 350°F (175°C). This is super important because it ensures even baking. While that’s warming up, line a 9×9-inch baking dish with parchment paper, letting it hang over the edges. This little trick makes it so much easier to lift the brownies out later!
Melt the Chocolate Mixture
Now, grab a saucepan and set it over low heat. Melt the butter in there, and then add the semi-sweet chocolate chips along with the cocoa powder and vanilla extract. Stir gently until everything is smooth and combined. Keep an eye on it—burnt chocolate is a sad sight! Once melted, take it off the heat and let it cool a bit.
Mixing Ingredients
In a large mixing bowl, beat together the eggs, egg yolk, white sugar, and brown sugar. You want to mix this for about 7–10 minutes until it’s light, fluffy, and creamy—trust me, this step makes a difference! Once you’ve achieved that airy texture, gently fold in the sourdough starter discard and the cooled chocolate mixture until just combined. It’s okay if there are a few streaks; we’ll take care of that in the next step!
Combine Dry Ingredients
Now it’s time to add the dry ingredients. Sift the flour and salt directly into the bowl, and fold them in gently. Be careful not to overmix! You want to maintain that lovely, thick batter without developing too much gluten.
Baking the Brownies
Spread the batter evenly into your prepared dish, making sure to get into the corners. Bake for 35–40 minutes. To check for doneness, stick a toothpick in the center—if it comes out with a few moist crumbs, you’re golden!
Cooling and Slicing
Once baked, let the brownies cool completely in the pan on a wire rack. This is crucial for getting those nice, clean slices later. Patience is key here, but the delicious reward will be totally worth it!
