Let’s Get Cooking!
Ready to dive into this deliciousness? Here’s how I make these Brown Butter Brookies!
1. Preheat and Prep
Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish. Greasing it well is essential for easy removal later; I usually use a little butter or cooking spray!
2. Mix the Cookie Dough
In a large bowl, combine your melted butter, light brown sugar, and granulated sugar. Whisk until everything is smooth and combined, about 1-2 minutes, you want all that sugar to dissolve completely!
3. Add Wet Ingredients
Now, add in your egg and vanilla extract, mixing until creamy and dreamy. Don’t skip the vanilla, it’s where all the magic happens!
4. Whisk in the Dry Ingredients
In another bowl, whisk together the all-purpose flour, baking soda, and a couple pinches of flaky sea salt. Gradually add this dry mixture to the wet ingredients. Stir until just combined; we don’t want to overmix here!
5. Fold in the Chocolate Chips
Gently fold in your chocolate chips, making sure they’re evenly distributed. This is the fun part, you can even eat a few along the way… no judgment here!
6. Make the Brownie Layer
Melt another cup of butter in a small saucepan. Remove it from the heat and stir in the cocoa powder, vanilla, and light brown sugar until smooth. This rich brownie batter is going to create a dreamy layer on top.
7. Layer It Up
Pour the cookie dough into your greased baking dish, spreading it evenly. Then, carefully pour your brownie mixture over the cookie layer. It doesn’t have to be perfect; just try to cover the cookie layer as best you can.
8. Bake
Pop those brookies into the preheated oven and bake for 25-30 minutes. You’ll know they’re done when a toothpick comes out mostly clean but with a few crumbs, this will ensure a gooey brownie texture.
9. Cool and Cut
Let them cool completely in the dish before slicing into squares. Trust me, the waiting will be worth it when you dive into this sweet treat!
