These cosmic brownie rolls are utterly indulgent—in the best way. They begin with the same soft milk-bread dough used for classic cinnamon rolls but are transformed with dark cocoa, a fudgy brownie-batter filling, and a rich chocolate cream cheese frosting.
Topped with brownie chunks and colorful candy-coated chips, every bite tastes like the gooey center of a brownie wrapped inside a pillowy roll.
How to Make Them
1
The first step in these rolls is making a tangzhong, a cooked flour-and-water roux that keeps the yeast dough moist and tender for days. It’s simple to make and uses common pantry ingredients.
2
Work the tangzhong into the yeast dough and knead until the dough is smooth and slightly tacky. The dough will develop elasticity and a glossy texture as you knead.
3
The filling is actual brownie batter—melted chocolate and butter combined with sugars, egg, vanilla, and a bit of flour to give it structure. Use a rubber spatula to spread it; metal spatulas can slip on the melted butter and make spreading harder.
4
Roll the dough out into a large rectangle and spread the brownie batter evenly to the edges. Smooth, even coverage helps create consistent swirls and a rich chocolate center in every roll.
5
Cut the rolled dough into twelve equal strips and roll each strip into tight spirals. Place the rolls in a 9×13 pan with space between them so they can rise evenly.
6
Let the rolls rise in a warm spot until they are nearly touching. They’re ready to bake when pressing the dough lightly reveals tiny bubbles under the surface.
7
Because the dough is dark, visual cues for doneness can be subtle. Use an instant-read thermometer in the center roll—aim for about 175°F for gooey, tender rolls.
8
Finish the warm rolls with a smooth chocolate cream cheese frosting and garnish with colorful candy-coated chips and mini brownie bites for that classic cosmic brownie look and extra texture.
These have a genuinely fudgy texture—the filling is inspired by a favorite brownie recipe—so if you’ve tried other chocolate sweet rolls, think of these as a darker, more brownie-forward version.
I hope you enjoy them!

Instructions
-
Make the tangzhong: whisk water and flour in a small saucepan and cook over medium heat, stirring constantly, until thickened into a smooth paste. Transfer to a bowl and let cool slightly.
-
In a stand mixer, combine bread flour, sugar, cocoa powder, yeast, and salt.
-
Add milk, cream, egg, and the tangzhong. Knead on low with the dough hook until a rough dough forms.
-
With the mixer running, add butter 1/2 tablespoon at a time, letting each addition incorporate. Continue kneading until the dough is smooth, elastic, and slightly tacky, about 10–12 minutes. Cover the bowl and set aside.
-
Prepare the brownie filling: melt butter and chocolate chips together, stir in cocoa powder, and let cool slightly. In a separate bowl, whisk granulated and brown sugar with egg, egg yolk, and vanilla. Whisk the melted chocolate into the sugar mixture, then fold in flour and salt until combined.
-
Line a 9×13 pan with parchment. Roll dough into a 21×15 rectangle and spread the brownie batter over the surface using a rubber spatula.
-
Cut the dough into twelve 1 3/4-inch strips, roll each strip into a spiral, and place them in the prepared pan. Cover and let rise in a warm spot for 1–2 hours, until doubled.
-
Preheat the oven to 325°F (162°C) near the end of the rise. Bake 25–35 minutes, or until the center roll reaches 175–185°F on an instant-read thermometer.
-
While the rolls bake, make the frosting: beat cream cheese and butter until smooth, add powdered sugar and cocoa on low, then beat on medium until light and fluffy. Mix in heavy cream, vanilla, and a pinch of salt.
-
Spread frosting over warm rolls and garnish with cosmic sprinkles and brownie bites just before serving.
