Brownies that Melt in Your Mouth

Honestly, every time I bake my one bowl fudge brownies, I think…it doesn’t get any better than this! So easy to bake and pure brownie bliss to eat. They just melt in your mouth with all their gooey fudgy goodness. We love love love these brownies!

I also can’t get enough of combining brownies and my other favorite treats. Like brownies and chocolate chip cookies in this truly scrumptious Brookie Pie (or these Peanut Butter Cup Stuffed Brookies). Well, the other night I proved my thoughts wrong when I topped a batch of these warm brownies with a creamy dreamy cookie dough frosting. I combined my love for brownies and cookies, and all I could think was why have I never thought to do this before?! To die for!

These ended up being the most perfect treat for girls’ night. I was trying to decide between cookies or brownies and went with brownies, but as they were baking, it dawned on me that I could combine the two into one decadent dessert for the girls and I to indulge in while we chatted the evening away. Talk about a sweet way to end the day!

These certainly didn’t last long. They’re one of those desserts I’d add to a list of ones you must try before you die! They’re out of this world amazing and they’re so easy to make. I used my one bowl fudge brownie recipe because they’re the best and the frosting can be whipped together in no time with ingredients you probably already have on hand.

Ingredients and Supplies

(see recipe card at the bottom of this post for measurements and details. To learn more about specific baking ingredients and how they function in baking recipes, reference my Complete Guide to Baking Ingredients)

Ingredients:

Unsalted butter: adds richness and moisture to the brownies as well as providing richness in the frosting.
Semi-sweet chocolate chips: melt into the batter to give the brownies their rich chocolate flavor and fudgy consistency.
Granulated sugar: sweetens the brownies while contributing to their moist, tender texture.
Unsweetened cocoa powder: deepens the chocolate flavor without adding extra sweetness.
Large eggs: bind the ingredients together and give the brownies structure while keeping them rich and moist.
Pure vanilla extract: enhances the overall flavor of the brownies with a warm, sweet note as well as elevates the flavor of the frosting.
All-purpose flour: provides just enough structure to hold the brownies together while keeping them fudgy.
Baking powder: gives the brownies a slight lift so they aren’t overly dense.
Kosher salt: enhances the chocolate flavor and balances sweetness of the brownies and the cookie dough frosting. Table salt will actually pack a saltier punch than Kosher salt so if you only have table salt, adjust accordingly.
Light brown sugar: gives the frosting sweetness, moisture, and that classic chocolate chip cookie dough flavor.
Heat-treated all-purpose flour: gives the frosting its cookie dough-like texture and body. Since the frosting isn’t baked, it’s important to heat-treat the flour before using it. Place the flour in a microwave-safe bowl and microwave on HIGH in 30-second intervals, stirring after each interval, until the flour reaches 165°F on an instant-read thermometer (this usually takes about 1 to 1½ minutes, depending on your microwave). Let the flour cool completely before using in the frosting.
Whole milk: loosens the frosting to create a smooth, creamy, spreadable consistency.
Mini chocolate chips: add little bites of chocolate throughout and complete the classic chocolate chip cookie dough experience.

How to Make Cookie Dough Frosted Fudge Brownies

To make the Brownies: Preheat oven to 350°F. Lightly grease a 9×13-inch baking dish with non-stick cooking spray and set aside.
Place the butter and chocolate chips in a large microwave safe bowl. Heat in the microwave for about 2 minutes, stirring every 30 seconds, until the chocolate chips are melted and smooth. Remove from microwave.
Whisk in the sugar and cocoa powder until well combined.

Add the eggs one at a time and whisk until smooth. Stir in the vanilla.

Spread the frosting evenly over the cooled brownies. Cut into squares and enjoy!

Storage

Store in an airtight container in the refrigerator. If stacking the brownies, place a sheet of parchment paper between layers to prevent sticking. They will stay fresh and moist in the refrigerator for up to 5 days. Enjoy chilled or let set at room temperature for 20-30 minutes to soften.

To freeze for longer storage, first chill the brownies in the refrigerator until the frosting is firm. Place slices on a baking sheet to freeze until solid, then wrap each brownie tightly in plastic wrap and store in a freezer-safe bag or container. Freeze for up to 2–3 months. Thaw overnight in the refrigerator or at room temperature for about 30–45 minutes before serving.
