Brown Butter Chocolate Chip Cookie Cake

I found the inspiration for this cookie cake in one of the simplest places, the grocery store bakery. I wanted to create a version that captured everything I loved about those nostalgic treats but with the homemade flavor I always wished they had. This recipe is my take on making that childhood favorite even better than I remember. It's also one of my favorite desserts to bring to birthdays and celebrations because I never like to show up empty handed.
The brown butter adds deep caramel notes, the combination of chopped chocolate and chocolate chips creates gooey pockets of melted chocolate, and a classic vanilla buttercream border brings back that unmistakable cookie cake look.
It's the kind of dessert that instantly feels familiar, whether you're celebrating a birthday, gathering with friends, or simply craving a little nostalgia. Soft, chewy, and packed with chocolate, it's a homemade version of the cookie cake many of us grew up loving, only even better.

Instructions
- 1
Preheat the oven to 325°F (163°C). Grease a 10-inch round cake pan and line the bottom with parchment paper.

Place the butter in a saucepan over medium heat. Cook until the butter foams and the milk solids turn deep golden brown with a nutty aroma, about 5–8 minutes. Immediately transfer the butter to a heatproof bowl, scraping in all of the browned bits. Let cool for about 20–30 minutes until warm but no longer hot.
- 3
In a medium bowl, whisk together the flour, cornstarch, baking soda, baking powder, and kosher salt.
- 4
In a large bowl, whisk together the cooled brown butter, dark brown sugar, and granulated sugar until smooth. Add the egg, egg yolk, and vanilla bean paste, then whisk until glossy and well combined.
- 5
Fold the dry ingredients into the wet ingredients until just combined. Gently fold in the chopped chocolate and chocolate chips, being careful not to overmix.
- 6
Press the dough evenly into the prepared pan, smoothing the top with an offset spatula or lightly damp hands. Press a few extra chocolate pieces onto the surface if desired.
- 7
Bake for 23–27 minutes, or until the edges are lightly golden and the center is just set with a slight sheen remaining.
- 8
Remove from the oven and immediately sprinkle with flaky sea salt. Allow the cookie cake to cool completely in the pan before decorating.
- 9
To make the buttercream, beat the softened butter until light and fluffy. Gradually mix in the powdered sugar. Continue beating until smooth and fluffy. Then fold in the vanilla bean paste, and a pinch of salt.

Pipe a buttercream border around the cooled cookie cake and decorate as desired.
Lauren's Note
- Browning the butter adds a rich caramel-like flavor that makes this cookie cake extra special.
- Be careful not to overbake. The center should still look slightly underdone when you remove it from the oven, it will continue to set as it cools.
- Sprinkle flaky sea salt on top while the cookie cake is still warm for the perfect sweet-and-salty finish.
- Store covered at room temperature for up to 4 days.
Frequently asked questions
Yes. The cookie cake can be baked up to 2 days in advance. Once completely cooled, wrap it tightly and store it at room temperature. Frost the day you plan to serve it for the freshest appearance.
The edges should be lightly golden while the center still looks slightly glossy. The cookie cake will continue to bake from the residual heat as it cools, giving you a perfectly chewy center.
Absolutely. Chopped chocolate creates melty pools throughout the cookie, but chocolate chips work just as well if that's what you have on hand.
Cornstarch helps create a softer, chewier texture that stays tender for days, giving the cookie cake that nostalgic bakery style bite.
