How to Make Sourdough Brown Butter Brookies
Let’s dive into creating this delicious Sourdough Brown Butter Brookies. I’ve broken down the process into simple steps, so follow along, and you’ll have a delightful treat in no time. We’re aiming for that perfect combination of chewy cookies atop fudgy brownies—a dessert lover’s dream!
Preheat and Prepare
First, preheat your oven to 350°F (175°C) and take a moment to grease and line your 9×9-inch baking pan with parchment paper. While that’s warming, you’ll get the magical brown butter ready!
Brown That Butter
In a small saucepan over medium heat, melt the ½ cup salted butter to begin browning it. Keep an eye on it and stir occasionally until it turns a lovely golden brown with a nutty aroma. This is key—the richness will enhance your entire dessert! Let it cool slightly while you prepare the rest.
Mix Wet Ingredients for the Cookie Layer
In a large mixing bowl, combine the browned butter, ½ cup brown sugar, and ¼ cup granulated sugar. Whisk them together until they are well blended. Next, toss in 1 egg, ½ cup sourdough discard, 1 tbsp heavy cream, and 1 tsp vanilla extract. Mix until everything is fully incorporated—it should feel creamy and wonderful!
Fold in Dry Ingredients for Cookies
Now, gently stir in the 1 cup + 6 tbsp all-purpose flour, ½ tsp baking soda, ½ tsp baking powder, pinch of salt, and ¾ cup chocolate chips. You want everything nicely combined, but don’t overmix; a little bit of lumpiness is perfectly okay! Set this bowl aside.
Melt the Magic for the Brownie Layer
In another medium saucepan, melt the 1 cup salted butter along with 70 g cocoa powder and the 6 oz dark chocolate chips until smooth and glossy. Stir it continuously; you want a luscious chocolate blend that smells divine!
Add Other Goodies for Brownies
Remove the mixture from heat and let it cool for a moment. Then, 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. Blend until smooth and delightful.
Incorporate Dry Ingredients into Brownies
Now, gently fold in the ½ cup + 1 tbsp all-purpose flour, ½ tsp salt, and ¾ cup chocolate chips. Again, be careful not to overdo it! Your brownie batter should be thick and rich, with gorgeous little chocolate bits mixed in.
Layer Those Delights
Spread your brownie layer evenly into the prepared pan. Then, take dollops of the cookie dough and place them on top of the brownie layer. Gently spread it out to create a marbled effect—you want to see both those luscious brownie and cookie layers!
Bake to Perfection
Pop the pan into the oven and bake for about 30-35 minutes. You’re looking for a set top that still feels fudgy in the center. The top edges will be slightly golden, but don’t overbake; you want that gooeyness!
Cool and Drizzle
Once baked, take them out of the oven and let them cool in the pan for a bit. Then, transfer to a wire rack to cool completely. Meanwhile, melt a ½ cup chocolate for drizzling and let it cool to a pourable consistency. Drizzle it generously over your brookies!
Cut and Enjoy
Once they are fully cooled, make to cut them into delightful squares (or rectangles, I don’t judge!). Serve them to your eager friends or keep them all to yourself for the cozy nights in. Either way, they’ll go fast!
How to Store Sourdough Brown Butter Brookies
If you’re lucky enough to have any leftovers, these brookies stay delicious for a few days. They can be stored at room temperature in an airtight container for 1-2 days. For longer preservation, you can keep them in the refrigerator for 3-4 days. If you want to freeze them, wrap individual portions tightly and store them for about 2-3 months. Just let them thaw at room temperature or pop them in the microwave for a few seconds for a warm, gooey treat!
Tips for Success
- Use room temperature ingredients for better mixing and texture.
- Don’t skip the browning process for the butter; it adds that incredible flavor.
- Make sure to not overbake—the center should still be fudgy when you remove them from the oven!
- Chill the final product in the fridge before cutting for cleaner squares.
- Use good-quality chocolate for that decadent chocolatey taste.
Serving Suggestions
- Pair with a scoop of vanilla ice cream for an indulgent dessert experience.
- Serve with a dollop of fresh whipped cream to elevate the presentation.
- Drizzle extra melted chocolate and sprinkle some sea salt for a touch of gourmet flair.
- Enjoy with a steaming cup of coffee or a glass of cold milk for balancing the sweetness.
- Garnish with fresh berries for a burst of color and freshness in every bite.
Enjoy these Sourdough Brown Butter Brookies! Each bite is a little moment of joy, crafting memories for you and your loved ones. Happy baking!
