Essential Ingredients
Here’s what you’ll need to make this delicious dish:
- Unsweetened Cocoa Powder: Use high-quality cocoa powder for rich flavor and color in your cookies.

- Brown Sugar: This adds depth and chewiness to the brownie texture—perfect for that fudgy feel.
- All-Purpose Flour: Choose a good quality flour for the best structure in your cookies.
- Butter: Unsalted butter provides flavor without adding extra saltiness; ensure it’s softened for easy mixing.
- Eggs: Essential for binding and creating that delectable texture; use large eggs for consistency.
- Vanilla Extract: A splash of vanilla enhances all those wonderful flavors in both the cookies and the frosting.
- Chocolate Chips: Semi-sweet chocolate chips offer gooey pockets of chocolate goodness inside each bite.
- Powdered Sugar: The main ingredient in the buttery frosting—helps create a silky smooth texture.
- Milk: A little milk thins out the frosting to perfection for easy spreading between those luscious cookies.
- Mini Chocolate Chips (for frosting): These add extra fun and flavor—because who doesn’t love more chocolate?

Let’s Make it together
Prepare Your Brownies: Preheat oven to 350°F (175°C). Grease and line an 8×8-inch baking pan with parchment paper for easy removal later. Mix melted butter and sugars until creamy.
Add Dry Ingredients: Incorporate cocoa powder, flour, and a pinch of salt into the mixture until just combined—watch out for cocoa clouds! Fold in chocolate chips gently.
Bake Those Brownies: Pour batter into prepared pan evenly and bake for 25-30 minutes until edges pull away slightly from sides—let cool completely in pan.
Create Cookie Dough Buttercream: Beat softened butter until fluffy. Gradually add powdered sugar while alternating with milk until desired consistency forms—add vanilla extract and mini chocolate chips.
Sandwich It Up: Once brownies are cool, cut them into squares or rectangles. Spread a generous layer of cookie dough buttercream on one piece and top it with another brownie piece. Repeat until all are assembled.
