What Is a Brookie?

A brookie is a combination of:

  • Brownie
  • Chocolate chip cookie

The brownie layer creates rich chocolate flavor while the cookie layer adds chewiness and buttery sweetness.

Adding sourdough makes the flavor deeper and more bakery-style.

Ingredients

For the Brownie Layer

  • 1/2 cup melted butter
  • 1 cup sugar
  • 2 eggs
  • 1 teaspoon vanilla extract
  • 1/3 cup cocoa powder
  • 1/2 cup all-purpose flour
  • 1/4 teaspoon salt
  • 1/2 cup chocolate chips
  • 1/2 cup sourdough discard

For the Cookie Layer

  • 1/2 cup softened butter
  • 1/2 cup brown sugar
  • 1/4 cup white sugar
  • 1 egg
  • 1 teaspoon vanilla extract
  • 1/2 cup sourdough discard
  • 1 1/4 cups flour
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 cup chocolate chips

Step-by-Step Instructions

Step 1: Prepare the Brownie Batter

Preheat your oven to 350°F (175°C).

Line an 8×8 baking pan with parchment paper.

In a bowl combine:

  • Melted butter
  • Sugar
  • Eggs
  • Vanilla extract

Whisk until smooth and glossy.

Now add:

  • Cocoa powder
  • Flour
  • Salt

Mix gently.

Fold in chocolate chips and sourdough discard.

The batter should look thick, rich, and shiny.

Spread it evenly into the prepared baking pan.

Step 2: Make the Cookie Dough

In another bowl cream together:

  • Softened butter
  • Brown sugar
  • White sugar

Mix until light and fluffy.

Add:

  • Egg
  • Vanilla
  • Sourdough discard

Now stir in:

  • Flour
  • Baking soda
  • Salt

Fold in chocolate chips.

The dough should be soft and thick.

Step 3: Assemble the Brookies

Take small portions of cookie dough and place them over the brownie batter.

Do not fully cover the brownie layer.

Leaving small gaps creates the perfect bakery-style appearance.

Add extra chocolate chips on top for even more gooey chocolate flavor.

Sprinkle a little flaky sea salt if desired.

Step 4: Bake

Bake for 30–35 minutes.

The edges should look golden brown while the center stays slightly soft.

Do not overbake because brookies continue cooking as they cool.

The chocolate should look melted and glossy.

Step 5: Cool Before Cutting

Allow the brookies to cool for at least 20–30 minutes.

This helps the layers set properly.

Cut into thick squares and serve warm.

The inside will be gooey, rich, and full of melted chocolate.

Tips for the Best Sourdough Brookies
