SUBSTITUTIONS AND TIPS
Need a swap? You can easily switch up some ingredients:
- Instead of brown sugar, you can use coconut sugar for a lower-glycemic option; though it won’t be quite as rich, the flavor will still be delightful.
- If you’re out of chocolate chips, try using chopped chocolate bars instead, which can add a lovely rustic touch.
- Don’t have sourdough discard? Use an equal amount of yogurt or buttermilk for a similar tang and moisture.
- Want to enhance the flavor? Add a teaspoon of espresso powder to the brownie mix to deepen the chocolate taste.

HOW TO MAKE SOURDOUGH BROWN BUTTER BROOKIES WITH CHOCOLATE DRIZZLE
Let’s dive into creating this wonderfully decadent Sourdough Brown Butter Brookies with Chocolate Drizzle. I’ve broken down the process into simple steps. Follow along, and you’ll have a delightful treat ready in no time. We’re aiming for perfectly baked layers that are fudgy and chewy with that irresistible chocolate drizzle on top.
Preheat and Prepare
First, preheat your oven to 350°F (175°C) and grease a 9×9-inch baking pan, lining it with parchment paper for easy fuss-free removal.
Brown the Butter for Cookie Layer
Next, in a small saucepan, melt the ½ cup salted butter over medium heat, allowing it to brown until it smells nutty. Keep an eye on it—it can go from perfect to burnt fast. Once it’s brown, remove it from heat, and let it cool slightly.
Cream the Sugars
In a mixing bowl, combine the browned butter, ½ cup brown sugar, and ¼ cup granulated sugar. Mix until the sugars are well incorporated and the mixture looks glossy.
Add Egg and Sourdough
Now, add in the egg, ½ cup sourdough discard, 1 tbsp heavy cream, and 1 tsp vanilla extract. Blend everything together until completely smooth and cohesive.
Fold in the Dry Ingredients
Next, gently fold in the 1 cup + 6 tbsp flour, ½ tsp baking soda, ½ tsp baking powder, pinch of salt, and ¾ cup chocolate chips until just combined. Set this cookie dough aside.
Melt for Brownie Layer
For the brownie layer, in a medium saucepan, melt the 1 cup salted butter with the 70 g cocoa powder and 6 oz dark chocolate chips, stirring until the mixture is smooth and completely combined.
Whisk in Wet Ingredients
Remove the pan from heat and whisk in 2 tbsp olive oil, 2 eggs, 1 egg yolk, ¾ cup brown sugar, ¾ cup granulated sugar, ½ cup sourdough discard, and 2 tsp vanilla extract until smooth and glossy.
Incorporate the Remaining Dry Ingredients
Now, fold in the ½ cup + 1 tbsp flour, ½ tsp salt, and ¾ cup chocolate chips or chunks. Be careful not to overmix; we want these heavenly brownies to stay as fudgy as possible.
Layer and Bake
Spread the brownie layer evenly in the prepared pan. Then, dollop the cookie dough over the brownie layer, gently spreading it out to create a marbled effect. Pop the pan in the oven and bake for 30-35 minutes. You’re looking for a set edge but still a bit fudgy in the center.
Drizzle and Serve
Once out of the oven, let the brookies cool completely. Melt the remaining ½ cup chocolate for drizzling, then drizzle it generously over the top. Cut into squares, and prepare yourself for a treat that will make your tastebuds dance!
HOW TO STORE SOURDOUGH BROWN BUTTER BROOKIES WITH CHOCOLATE DRIZZLE
The leftovers of these brookies are still just as decadent! You can store them at room temperature in an airtight container for up to 3 days. If you want to keep them longer, pop them in the fridge for up to 4 days or freeze them for 2-3 months. Just thaw at room temperature before indulging again. You may want to warm them up slightly for that fresh-out-of-the-oven experience!
TIPS FOR SUCCESS
- Be patient while browning the butter; it’s a key step for deep flavor.
- Make sure your eggs are at room temperature for the best emulsion.
- Don’t overmix the batter once the flour is added; this keeps the baked goods tender.
- When adding the cookie dough on top, don’t worry about making it perfect; the ‘marbled’ look adds to its rustic charm!
SERVING SUGGESTIONS
- Pair these brookies with a scoop of vanilla ice cream for an indulgent sundae.
- Serve with a dollop of fresh whipped cream and a sprinkle of sea salt on top.
- Enjoy with a cup of coffee or hot chocolate for an ultimate cozy experience.
- Garnish with a dusting of powdered sugar for a pretty presentation.
- Slice into smaller squares for a delightful dessert platter at your next gathering.
Enjoy diving into these Sourdough Brown Butter Brookies with Chocolate Drizzle—I can’t wait to hear how they turn out for you! They truly are a delightful blend of my favorite things and a sweet reminder that life is better with a little chocolate.
