This blissful s’mores cinnamon roll cake is super delicious and calls for five simple ingredients. Serve this fantastic dessert for any occasion!

This s’more cake has all the wonderful open flame flavor of traditional s’mores, but texturally it is a blend of a cinnamon roll and a skillet cookie. It combines the best elements of all these desserts into one delicious treat! Serve this ooey gooey cake with a scoop of vanilla ice cream.

Ingredients

2 tubes of cinnamon roll dough with icing included
Graham crackers
Chocolate bars, about 5
Miniature marshmallows (you’ll need roughly 1 1/2-1 3/4 cups)
Unsalted Butter
10″ cast-iron skillet (seasoned, of course!)

Wood recommendations: Use lighter flavored pellets like maple, cherry, or apple.

How to make a s’mores cinnamon roll cake:

Remove the individual cinnamon roll dough discs from the first tube, and stack them one on top of the other. Press the stack down onto a lightly floured surface with the palm of your hand. Turn the dough over.
Using your rolling pin, roll the dough into a uniform shape, about 8″ in diameter. This process will take some elbow grease, so don’t give up!
Grease your cast-iron skillet well with non-stick cooking spray or brush with vegetable oil.
Lay the first layer of rolled-out dough in the skillet. Brush with a little melted butter, top with crushed graham crackers, chopped chocolate, and mini marshmallows.

Second Layer of s’mores cake:

Roll out the second tube of dough as instructed above. However, this time, score the dough halfway through with a sharp knife. Be careful not to cut all the way through.
Brush with butter, top with graham cracker crumbs, and then carefully wedge some of the marshmallows and chocolate into the scored bits of dough. Set aside.

Grill set-up and baking:

Preheat your grill to 325 degrees F.
Once it is fully heated, place the skillet onto the grill grates. Close the lid, and cook for 40-45 minutes. Check on it after 35 minutes to see how it is progressing.
The cake is done once the dough is golden brown, no longer moist in the center, and stiff to the touch. The marshmallows on top will appear toasted, and the chocolate will melt a little.

Serving pellet grill s’mores cake:

Remove the s’mores cake from the grill, and let it rest for 15 minutes. Using a large spatula, carefully remove the cake from the pan and set it onto a clean cutting board.
Drizzle with warmed icing (included in the tube), cut into 6-8 equal portions, and serve with a scoop of vanilla ice cream, and some additional crumbled graham crackers and chopped chocolate on top.
Serve this delicious cake at cookouts, parties, birthdays, holiday gatherings, Sunday dinners, and on Halloween!

Leftovers:

Store the leftover s’mores cake in an airtight container in the refrigerator for up to 3 days after preparation. Reheat in the microwave for 20-30 seconds before eating.
