At roughly 250 calories per serving (based on 24 servings), they’re perfect for sharing at weekend gatherings, potlucks, or cozy movie nights at home.

KEY INGREDIENTS IN BROWN BUTTER BROOKIES
Every unforgettable brookie starts with a handful of essential ingredients, each playing a crucial role in creating that decadent balance of brownie richness and cookie chewiness. Below, you’ll find the stars of the show—bold, beautiful, and ready to transform into something truly spectacular.
- Unsalted butter
Browned to perfection, this ingredient adds a deep, nutty complexity that elevates both the brownie and cookie layers. Browning selenium-rich butter releases toasted notes that distinguish these brookies from the rest.
- Granulated sugar
Provides the primary sweetness and contributes to a smooth, shiny texture in the brownie base. It also helps with the structural integrity, ensuring each bite holds its shape.
- Light brown sugar
Adds molasses undertones and extra moisture. Used in both layers, it helps create a chewy cookie top and accentuates the caramelized tones of the brown butter.
- Large eggs
Act as a binding agent, creating structure and richness. Their proteins set during baking, ensuring a tender crumb without becoming too dense.
- Vanilla extract
Brings warmth and aromatic depth, rounding out the chocolate’s intensity and enhancing the buttery notes.
- All-purpose flour
The backbone of both layers, it gives the brookies structure while allowing enough softness for that signature gooey center.
- Unsweetened cocoa powder
Contributes rich, chocolatey flavor without added fats or sugars. It deepens the color and amplifies the fudginess of the brownie portion.
- Baking soda
Helps the brookies rise gently, creating a slightly airy texture that prevents them from feeling too heavy.
- Salt
Balances sweetness and accentuates flavors. A small pinch in the brownie layer makes the chocolate taste more vibrant.
- Semi-sweet chocolate chips
Melt into pockets of gooey delight throughout the brownie layer. Their moderate sweetness pairs perfectly with the brown butter’s toasty notes.
- All-purpose flour (cookie layer)
Gives the cookie topping just enough structure to hold onto those melty mini chocolate chips while still remaining tender.
- Baking powder
Provides lift in the cookie layer, ensuring it doesn’t compress the brownie beneath and creates a light, cakey contrast.
- Light brown sugar (cookie layer)
Adds chew and moisture specifically to the cookie dough, giving it that soft, pliable texture that contrasts the dense brownie.
- Large egg (cookie layer)
Binds cookie ingredients and adds richness, ensuring the topping doesn’t crumble away when you cut into your brookies.
- Vanilla extract (cookie layer)
Offers aromatic warmth that complements the cocoa in the brownie layer, tying both components together seamlessly.
- Mini chocolate chips
Provide little bursts of chocolate throughout the cookie top, creating perfect melty dots of sweetness in every bite.
HOW TO MAKE BROWN BUTTER BROOKIES
Let’s walk through bringing these two classic desserts together in one pan. The process is surprisingly straightforward, but each step is essential to achieving that signature texture and depth of flavor. Gather your ingredients, preheat, and get ready to taste pure bliss.
1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper to ensure the brookies slide out cleanly once they’re baked to perfection.
2. Begin by making the brown butter: in a saucepan over medium heat, melt the unsalted butter. Stir continuously with a wooden spoon or heatproof spatula until it foams, sizzles, and turns a golden-brown hue, about 5–7 minutes. Remove from heat and let it cool slightly so it won’t scramble the eggs in the next step.
3. In a large mixing bowl, whisk together the granulated sugar and packed brown sugar. Pour in the warm brown butter and mix until the sugars dissolve and the mixture is smooth and glossy.
4. Add the 3 large eggs and 2 teaspoons of vanilla extract, whisking well until fully incorporated. The batter should look silky with no streaks of egg white or unmixed sugar.
5. For the brownie layer, sift together the all-purpose flour, unsweetened cocoa powder, baking soda, and salt directly into the bowl. Gently fold the dry ingredients in until just combined, then stir in the semi-sweet chocolate chips to distribute them evenly.
6. In another mixing bowl, prepare the cookie layer by combining packed brown sugar, the large egg, and vanilla extract. Whisk until the mixture is light and slightly fluffy.
7. Sift together the remaining cup of all-purpose flour and baking powder, then gradually add it to the wet ingredients, stirring until a soft dough forms. Fold in the mini chocolate chips so they’re evenly dispersed.
8. Pour the brownie batter into the prepared pan, using a spatula to spread it evenly into the corners for a uniform bake.
9. Drop spoonfuls of the cookie dough over the brownie batter. Use a spatula to gently spread the cookie dough, but don’t worry about achieving perfect coverage—swirls and pockets are part of the charm.
10. Bake in the preheated oven for 30–35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs clinging to it.
11. Allow the brookies to cool completely in the pan. This resting time gives them a chance to set beautifully, making them easier to cut into neat squares for serving.
SERVING SUGGESTIONS FOR BROWN BUTTER BROOKIES
Once your Brown Butter Brookies are cool and sliced, it’s time to elevate the experience even further. Whether you’re hosting a gathering or indulging in a solo treat, these serving ideas will bring a smile to every dessert lover’s face. Feel free to mix and match based on your mood—these brookies are incredibly versatile!
- Warm with ice cream
Place a freshly cut brookie square on a plate and top with a generous scoop of vanilla bean ice cream. The contrast of the warm brookie and cold ice cream creates a delightful temperature dance.
- Drizzle with salted caramel
Warm some homemade or store-bought salted caramel sauce and lightly drizzle it over each square. The sweet-salty combo pairs impeccably with the deep brown butter notes.
- Dust with powdered sugar
For a simple, elegant touch, use a fine-mesh sieve to sprinkle confectioners’ sugar over the top. It adds a light sweetness without overpowering the rich chocolate flavors.
- Build a dessert board
Arrange brookie squares alongside fresh berries, whipped cream, and extra chocolate chips on a wooden board. Guests can help themselves and customize each bite to their liking.
HOW TO STORE BROWN BUTTER BROOKIES
Proper storage is key to keeping your brookies tasting just-baked for days to come. Whether you need to prep ahead for a party or want to savor these treats over the week, follow these tips to maintain that perfect balance of fudgy brownie and chewy cookie goodness.
- Room temperature
Store cooled brookies in an airtight container at room temperature for up to 3 days. Place a sheet of parchment paper between layers to prevent sticking and maintain freshness.
- Refrigeration
If you prefer a firmer texture or need to keep brookies longer, pop them in the fridge in a sealed container for up to 5 days. Before serving, let them sit at room temperature for 20 minutes so they regain their chewiness.
- Freezing
For ultimate longevity, wrap individual brookie squares tightly in plastic wrap, then store them in a zip-top freezer bag. Freeze for up to 3 months. Thaw overnight in the fridge, then bring to room temperature or warm briefly in the microwave.
- Reheating
To revive that just-baked warmth, microwave a single brookie for 10–15 seconds or place on a baking sheet in a 325°F oven for 5 minutes. Be careful not to overheat, or you’ll lose the gooey center.
