The marshmallow mixture starts out loose and glossy, then turns into a dough you can shape once the powdered sugar is worked in. Pecan Log Roll gets its chewy center from marshmallow creme rather than a cooked sugar syrup, so there’s no thermometer stage to manage. Each slice has a soft vanilla middle, a thin caramel layer, and pecans pressed all around.
I shape the dough into two logs and chill them before coating. That short rest firms the nougat so it’s easier to handle under the offset spatula, and the caramel has a steady surface to cling to. Once the coating sets, the logs cut into neat rounds with a clear stripe of caramel between the nougat and pecans.
Kitchen Note
Keep the caramel bowl over the gently simmering water while you coat the logs. It stays smooth and spreadable, so you’re not fighting a thickening layer halfway through.
Save Pecan Log Roll for your next candy tray: chewy vanilla nougat, a soft caramel coat, and pecans in every bite.
Why the Nougat Needs a Stiff Dough Before It Ever Sees Caramel
The center has to hold its shape before the caramel goes on. Marshmallow creme and butter start out soft, and powdered sugar is what turns them into a workable nougat. Add it gradually, stirring in half-cup portions, so you can stop when the dough is stiff instead of overshooting into a dry, crumbly mixture.
When the dough is ready, it should come together smoothly after a brief knead and feel firm enough to shape into a log. A loose, sticky mixture will flatten when you spread caramel over it; a dry one is harder to press into an even cylinder. The short knead brings the mixture together, while the refrigerator rest firms the shaped logs without changing the chewy character of the center. That balance is what gives each slice a clean, even cross-section.
What Gives These Logs Their Chewy Center and Crisp Pecan Coat
- Marshmallow creme — This gives the nougat its soft, stretchy texture and blends readily with softened butter. Regular marshmallows aren’t a direct swap here; their shape and consistency make it harder to get the same smooth dough.
- Powdered sugar — Its fine texture helps the dough come together without the graininess granulated sugar would leave. Keep it nearby as you mix, but work it in gradually so the nougat doesn’t turn dry.
- Soft caramels and heavy cream — Individually wrapped soft caramels melt into a coating that firms up around the logs. The cream loosens the melted candy so it spreads; caramel sauce is too fluid to make the same shell.
- Finely chopped pecans — Small pieces cling more evenly than large chunks and make the logs easier to slice. Fresh-tasting pecans matter because their nutty flavor is front and center; chop them finely and spread them in a shallow dish before you begin coating.
- Butter and vanilla — Softened butter blends smoothly into the marshmallow creme, while vanilla gives the center its familiar candy-shop note. If you use salted butter, leave out the kosher salt so the nougat doesn’t become too salty.
Shape, Chill, and Coat the Logs Without Losing Their Edges
Stir the Marshmallow Base Smooth
Combine the marshmallow creme, softened butter, vanilla, and kosher salt in a large bowl. Stir until the mixture looks even and glossy, with no streaks of butter remaining. If the butter is still firm, it’s harder to blend smoothly into the creme. The mixture will be soft at this stage; the powdered sugar gives it structure next.
Work the Sugar Into a Firm Nougat
Stir in powdered sugar a half cup at a time, letting each addition disappear before adding more. The dough will thicken gradually, then become stiff enough to pull together. Knead briefly until it feels smooth rather than sticky. Stop once it holds together; extended kneading isn’t needed.
Shape and Chill Two Even Logs
Divide the dough in half and shape each piece into an 8-inch log. Set them on a parchment-lined baking sheet, leaving room to lift and turn each one when you coat it. Refrigerate for 30 minutes, until the logs feel firm. If they still bend easily when lifted, give them a little longer to chill before coating.
Melt the Caramels Gently
Set a heatproof bowl over a small saucepan of gently simmering water, then add the unwrapped caramels and heavy cream. Stir for 5 to 8 minutes, until the mixture is smooth and spreadable. Keep the water at a gentle simmer rather than a hard boil. A harsh boil can make the bowl awkward to handle and the caramel harder to control.
Press on the Pecans and Let the Coating Set
Spread the finely chopped pecans in a shallow dish. Coat one chilled log on all sides with caramel using an offset spatula, then roll it through the pecans and press them in gently; repeat with the second log. Refrigerate the coated logs for 30 minutes, until the caramel is set. Slice each log into 12 pieces for 24 servings.
Two Easy Ways to Change the Pecan Log Roll
Make a dairy-free batch
Use dairy-free marshmallow creme, unsalted vegan butter, dairy-free soft caramels, and canned coconut cream in place of the corresponding ingredients, keeping the amounts the same. The coconut cream can add a faint coconut note, and different dairy-free caramels may set a little softer, so chill the coated logs until firm before slicing.
Trade pecans for toasted coconut
Use cooled, toasted shredded coconut in place of the chopped pecans and press it onto the caramel as you roll each log. The coating will be sweeter and lighter, with a softer bite than the nutty pecan crust.
Storage and Reheating
- Refrigerator: Store the logs or slices in an airtight container for up to 1 week. The pecans may lose a little crunch as they sit.
- Freezer: Wrap the logs tightly and freeze for up to 2 months. Thaw them in the refrigerator before slicing.
- Reheating: No reheating is needed. Serve the slices chilled or let them rest at room temperature until they’re easier to bite; don’t microwave them, since the caramel can heat unevenly.
