The Twist
This is a fun cookie dough and brownie combo, just like the dessert that’s been popular at Disney recently. You get the best of both treats in every bite, with a layer of sugar cookie dough on the bottom and a fudgy Cosmic Brownie right on top.
Ingredient Highlights
- Sugar cookie dough: Be sure to use a package specifically labeled safe to eat raw since the dough isn’t baked.
- Vanilla ice cream: Let it soften just enough to spread easily without letting it melt.
- Cosmic Brownies: Arrange them evenly over the top so each finished square gets its own brownie.
- Rainbow sprinkles: Jimmies work especially well because they keep their shape and add a little texture.
Cosmic Brownie Ice Cream Bars
Ingredients
- 1 package edible sugar cookie dough- be sure it says Safe to Eat Raw like this one
- Rainbow sprinkles/jimmies
- 1 pint vanilla ice cream, softened but not melted
- 1 package Cosmic Brownies (16 brownies needed)
Instructions
- Line an 8-inch square baking dish with parchment paper, leaving a little overhang on the sides. Spray very lightly with nonstick spray.
- Press the sugar cookie dough evenly into the bottom of the pan.
- Spread the softened vanilla ice cream over the cookie dough in an even layer.
- Sprinkle rainbow jimmies over the ice cream.
- Arrange the Cosmic Brownies on top in a 4 x 4 pattern, gently pressing them into the ice cream.
- Freeze until completely firm.
- Use the parchment paper to lift the dessert from the pan. Cut into squares, using each Cosmic Brownie as your guide.
- Let the bars sit at room temperature for a few minutes before serving so the brownie and cookie dough soften enough to easily bite through.
FAQ
How long should Cosmic Brownie Ice Cream Bars freeze?
Freeze them until the ice cream is completely firm, ideally at least 4 hours or overnight.
Can I make these ahead of time?
Yes. They’re a great make-ahead dessert and can stay covered in the freezer until you’re ready to serve them.
Do I need to thaw them before serving?
Yes, just for a few minutes. The brownies and cookie dough soften slightly, which makes the bars much easier to bite and cut.
Can I use a different ice cream flavor?
Absolutely. Chocolate, birthday cake, or cookies and cream would all work, but vanilla lets the Cosmic Brownies stand out the most.
How should I store leftovers?
Keep the bars tightly covered in the freezer so the ice cream stays firm and doesn’t pick up any freezer flavors.
Sprinkle of Fun
Save these for a ’90s throwback movie night with favorites like Clueless, 10 Things I Hate About You, The Parent Trap, or Space Jam.
