These sourdough brownies for Valentine's Day are fudgy and festive. They're made with gooey chocolate butter, sourdough starter discard, and a festive sprinkle of candy on top.
Prepare. Preheat the oven to 350° F. Line an 8"x8" or 9"x9" baking dish with parchment paper or grease it thoroughly with butter.
Melt the Butter. In a small saucepan, melt the butter on low heat. Keep the temp as low as possible. You don't want the butter to get hot and separate, or it will make your brownies greasy.
8 tablespoon butter
Add Chocolate and Vanilla. Remove the melted butter from the heat and add the dark chocolate chips and vanilla.
1 cup dark chocolate chips, 2 teaspoon vanilla extract
Melt the Chocolate. Stir until the chocolate is thoroughly melted and combined. If the chocolate isn't melting, put it back on the burner over low heat, stirring constantly. Once combined, set aside.
Combine Dry Ingredients. In a medium bowl, whisk together the flour, sugar, cocoa powder, and salt. Set aside.
3/4 cup flour, 1 1/4 cup granulated sugar, 1/4 cup cocoa powder, 1/2 teaspoon salt
Combine Eggs and Discard. In a small bowl, stir together the whole eggs, egg yolk, and sourdough discard. Mix until thoroughly combined.
2 whole eggs, 1 egg yolk, 1/2 cup sourdough discard
Make the Brownie Batter.Pour the egg and chocolate-butter mixtures into the dry ingredients. Stir until combined with no lumps.
Transfer Batter and Decorate. Transfer the brownie mixture into the prepared baking dish. Use a spoon or spatula to spread the mixture evenly. Sprinkle the top of the brownie mixture with the M&M's.
1/2 cup Valentine's Day M&M's
Bake. Bake for 35-40 minutes or until a toothpick comes out clean.
Enjoy. Remove from the oven and cool completely before slicing (this is the hardest part of the recipe).
Notes
Let the brownies cool to room temperature before cutting. This will help them develop flavor and hold their shape.
If you can stand it, after they cool, I recommend refrigerating them for a while (we usually eat a few before popping them in the fridge).
The chocolate candies will inevitably crack while baking and cutting the brownies. I like adding a few fresh M&M's on top before serving for a nice aesthetic.
If you are making sourdough brownies for digestibility or want more sourdough tang, long-ferment the batter in the fridge for up to 3 days.
