Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

For the Brownie Layer:

• 1/2 cup unsweetened cocoa powder
• 1/2 cup all-purpose flour
• 1/4 teaspoon salt
• 1/4 teaspoon baking soda
• 1/2 cup coconut oil or melted butter
• 1 cup coconut sugar or brown sugar
• 2 teaspoons vanilla extract
• 2 eggs

For the Cookie Layer:

• 3/4 cup all-purpose flour
• 1/4 teaspoon baking soda
• 1/4 teaspoon salt
• 1/3 cup coconut oil or butter, softened
• 1/3 cup brown sugar
• 1 teaspoon vanilla extract
• 1 tablespoon plant-based milk or regular milk
• 1/2 cup chocolate chips

Directions

1. Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper.
2. For the brownie layer, whisk together cocoa powder, flour, salt, and baking soda in a bowl.
3. In a separate bowl, combine the coconut oil (or butter), sugar, vanilla, and eggs. Mix until smooth, then stir into the dry ingredients. Spread the brownie batter evenly into the prepared pan.
4. For the cookie layer, cream the softened coconut oil or butter with the brown sugar, vanilla, and milk until smooth. Add the flour, baking soda, and salt, and mix well. Fold in the chocolate chips.
5. Drop spoonfuls of the cookie dough over the brownie layer and gently press down to cover.
6. Bake for 25–30 minutes, or until the cookie top is golden and the center is just set.
7. Let cool in the pan before slicing for neat bars—or serve warm for a gooier texture.

FAQs

Can I use boxed brownie mix for this recipe?

Yes, you can use your favorite boxed brownie mix for convenience and follow the cookie layer steps as directed.

Yes, use plant-based milk and butter alternatives, and substitute the eggs with flax eggs (1 tbsp flaxseed meal + 3 tbsp water per egg).

What size pan should I use?

An 8×8-inch square baking pan is ideal. Using a larger pan will result in thinner bars.

How thick are these bars?

They are thick and hearty, approximately 1.5 to 2 inches depending on the pan and ingredient variations.

Can I double the recipe?
