Chocolate and caramel have a way of making a regular weeknight feel like a little celebration. In my kitchen, these rolo cookies are the kind of shortcut treat I lean on when the calendar is packed, but the cookie exchange tray still needs something that gets people hovering near the dessert table.
Most versions either bake the caramel into a hard lump or let it leak into sticky puddles. This method uses one professional trick so beginners get that molten center on purpose, not by accident, every single time.
Why You’ll Love This Recipe
The Double-Chill Method: Freezing the Rolo candies for 30 minutes keeps the caramel where it belongs, tucked inside the dough instead of disappearing into it.
Sweetness, balanced: A pinch of flaky sea salt on warm cookies cuts through the chocolate cake mix richness, and the whole bite tastes grown-up instead of cloying.
That perfect contrast: You get a fudgy, chewy exterior with a soft, liquid caramel filling, the kind that stretches just a little when you break one open.
High reward, low effort: The cake-mix base moves fast, similar to the shortcut used in cake mix brownies, and nobody ever guesses how simple it was.
Ingredients and Substitutions
These rolo cookies keep it simple on purpose. A chocolate cake mix makes a thick, glossy dough, and the Rolo candies do all the heavy lifting for that caramel filling.
Ingredients
- 1 box chocolate cake mix
- 1/3 cup oil
- 2 eggs
- Rolo candies
Ingredient Notes & Substitutions
Chocolate cake mix: For a thicker, more cookie-like consistency, I reach for “Chocolate Fudge” more often than “Devil’s Food,” which can bake up a touch lighter and cakier.
Dutch-processed cocoa cake mixes: These tend to look darker and taste a bit smoother, because alkalizing cocoa reduces acidity. In a cookie, that often reads as deeper chocolate color and less sharpness.
Eggs: Room temperature eggs blend in more cleanly, helping the dough turn shiny instead of streaky, and eggs act as powerful emulsifiers for a smoother, more cohesive texture.
Oil: This recipe is designed around oil for chew and softness even after cooling. Butter can taste lovely, but it sets firmer once the cookies sit.
Metric conversions: A standard cake mix box is roughly 432g, and 1/3 cup oil is approximately 80ml for international bakers.
How to make rolo cookies
Double-chill prep
- Unwrap the Rolo candies and freeze them for at least 30 minutes. That cold center is your insurance policy against caramel blowouts.
- Heat the oven to 350°F (175°C). While it heats, line a baking sheet with parchment paper so any caramel drips lift off cleanly.
Mix the cookie base
- In a large bowl, combine the chocolate cake mix, oil, and eggs. Stir until the dough looks thick and glossy, and it smells like rich cocoa the second you lean in.
- Let the dough sit for a minute if it feels very soft, it should be scoopable and dense, not pourable.
Stuff, seal, and bake
- Scoop up a small piece of dough, flatten it in your palm, and set a frozen Rolo in the center. Fold the dough up and around it, then roll into a smooth ball so no caramel is peeking through.
- Place the dough balls on a greased cookie sheet about 2 inches apart. Bake for 8 to 10 minutes, pulling them when they look slightly underdone and soft in the middle.
- Let the cookies cool for 1 minute, then lift them off the cookie sheet carefully. They will firm up as they settle, and the caramel will stop sloshing.
Secrets for Perfection
Altitude adjustments: At higher elevations, a tablespoon of flour can help prevent overspreading. The best reference points are classic high-altitude baking adjustments, because small changes make a big difference up there.
The science of softness: The double-chill works like a temperature buffer. The cookie structure sets in the oven before the caramel center fully liquefies, so you get a molten core without a puddle.
Oil vs. butter: Oil stays fluid at room temperature, so the crumb stays chewy for days. Butter firms as it cools, which can push these closer to “brownie-bite” texture instead of gooey cookie.
Pro Tips & Troubleshooting
Pro Tips
- Perfectly uniform “cookie cups” happen when you bake the dough in a mini muffin tin, because the walls help hold the caramel center.
- If the dough is too sticky to roll, lightly coat your hands with canola oil or a dusting of flour.
- Unwrapping a whole pack goes faster if you roll the foil tube on the counter first, it loosens the candies without tearing nails up.
- A thin drizzle of cream cheese glaze adds a bakery-style finish without extra fuss.
Common Mistakes to Avoid
- The hard caramel trap: Hard caramel squares cool into tooth-sticking rocks, Rolo candies stay soft and molten in the center.
- Skipping parchment paper: If one leaks, caramel turns into edible glue, and parchment paper saves your cookies and your pan.
- Overbaking: Pull them when they still look a little soft, carry-over heat finishes the set while keeping the center gooey.
- Poor sealing: Any exposed candy edge will find the baking sheet, so take an extra second to smooth the dough seam.
Serving & Storage
How to Serve
These are at their absolute best warm, when the caramel filling is still fluid. At parties, I like setting them out with milk, or plating one with vanilla bean ice cream for the full dessert moment.
For holiday exchanges, a mixed tray feels special with something seasonal alongside, and eggnog cookies bring that cozy winter spice to balance the chocolate.
Storage and Make-Ahead Instructions
Room temperature: Store in an airtight container for up to 4 days, keeping them out of direct sun or heat. The guideline of freshness for up to 4 days lines up well with how these hold their texture.
Softening hack: If they firm up, a quick 5 to 10 seconds in the microwave brings back that molten center. Let it sit for a few seconds before biting, the caramel gets hot fast.
Freezing unbaked dough balls: Stuff and roll the dough around the frozen Rolo, then freeze the balls on a tray until solid. Move them to a freezer bag and keep up to 3 months, baking straight from frozen at 350°F (175°C) and watching closely within the same 8 to 10 minute window.
Freezing baked cookies: Cool completely, then freeze in a tight container with parchment between layers. Thaw at room temperature, then warm briefly to revive the gooey middle.
Summary of Sweet Success
Between the cake mix shortcut and the double-chill technique, these rolo cookies come out reliably fudgy outside and molten in the middle. That tiny pinch of flaky salt is the finishing move that makes people ask what your secret is.

- Baking Sheet
- Parchment Paper
- Large Mixing Bowl
- Cookie Scoop
Ingredients
- 1 box chocolate cake mix

Instructions
Double-chill prep
- Unwrap the Rolo candies and place them in the freezer for at least 30 minutes to prevent the caramel from leaking during baking.
- Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper for easy removal.
Mix the cookie base
- In a large bowl, combine the chocolate cake mix, oil, and eggs, stirring until the dough is thick, glossy, and well combined.
- Allow the dough to rest for one minute to firm up if it feels too soft to handle.
Stuff, seal, and bake
- Scoop a small portion of dough and flatten it in your hand. Place a frozen Rolo in the center and wrap the dough around it, rolling it into a smooth ball to seal the candy completely.
- Arrange the dough balls on the prepared baking sheet about 2 inches apart and bake for 8 to 10 minutes until slightly underdone.
- Let the cookies cool on the sheet for 1 minute to firm up before transferring them to a wire rack.
