Brownie Cookies
- 4 ounces dark chocolate bar (preferably semi-sweet or bittersweet)
- 5 tablespoons vegetable oil
- 1 box brownie mix (18.3–18.4 ounces)
- 2 large eggs (room temperature)
- 1 teaspoon vanilla extract
Vanilla Mousse
- 1 ½ cups heavy cream
- 3 tablespoons instant vanilla pudding mix (about 1 ounce)
- 1 ½ tablespoons powdered sugar
- ¼ teaspoon vanilla extract
Decorations
- 3 tablespoons thick fudge sauce (slightly warmed for drizzling)
- Sprinkles
- Maraschino cherries
- Prepare Brownie Cookies: Preheat your oven to 350°F and line a large baking sheet with parchment paper to prevent sticking.
- Melt Chocolate and Oil: In a large microwave-safe bowl, microwave the dark chocolate bar and vegetable oil in 20-second intervals, stirring between each interval until the mixture is smooth and fully melted. Let this mixture cool for about 5 minutes.
- Mix Eggs and Vanilla: Whisk in the two room temperature eggs and one teaspoon of vanilla extract briskly for 90 seconds to create the signature crackled top on the cookies.
- Add Brownie Mix: Fold in the entire box of brownie mix using a spatula until the dough is thick, smooth, and evenly combined.
- Shape Cookie Dough: Using a 1/3 cup measuring cup or scoop, portion out eight dough balls. Hand-shape each ball into a thick disk about 1 inch high. Place them on the prepared baking sheet spaced about 3 inches apart to avoid merging.
- Bake Cookies: Bake one sheet at a time for 15-17 minutes or until the cookies are puffed and have crackled edges. They will look gooey but will set as they cool. Remove when an instant-read thermometer reaches at least 165°F. Let them cool completely before decorating.
- Make Vanilla Mousse: In a medium bowl, gently whisk together heavy cream, instant vanilla pudding mix, powdered sugar, and vanilla extract until the pudding mix dissolves (about 1-2 minutes). Then whip with a hand mixer on low speed until the mixture forms soft to medium peaks. Avoid over-whipping. Chill in the refrigerator until ready to frost.
- Decorate Cookies: Once cookies are completely cooled, scoop about 3 tablespoons of the vanilla mousse onto the center of each cookie using a cookie scoop. Drizzle generously with warm fudge sauce. Finish by sprinkling colorful sprinkles and topping each with a maraschino cherry for the perfect sundae look.
Notes
- The recipe works best with dark chocolate bars rather than chips to ensure proper melting and texture.
- Room temperature eggs are essential for achieving the desired smooth batter and crackly cookie tops.
- Cookies will seem very soft and gooey right out of the oven but will firm up as they cool.
- Using an instant-read thermometer helps prevent overbaking; cookies are best removed when they reach 165°F internally.
- Thick fudge sauce should be slightly warmed before drizzling for easy application.
- You can bake a test cookie first to ensure your oven settings and texture preference match.
