Apparently banana is a fall flavor now and honestly… we’re not mad about it. 🍌

So obviously we had to give the viral smashed date s’mores another XO spin — this time with Banana Pudding OMG and a pistachio drizzle.

Here’s how to make them:

🍌 Smash your dates
🍪 Top with graham crackers
☁️ Cover with Banana Pudding Ooey Marshmallow Goodness
🍫 Add melted chocolate
💚 Drizzle with pistachio cream
🍪 Finish with more crushed grahams

Pop them in the fridge until everything sets, break them apart, and enjoy your very gooey little treat.

Banana + chocolate + pistachio + marshmallow might have just convinced us that banana belongs in fall after all.

Are we accepting banana into the official fall flavor lineup? Yes or absolutely not? 👀

Our Chocolate Chip S’mores Dip is dangerously easy:

🍫 Melt chocolate chips in the microwave
☁️ Cover with XO Chocolate Chip Marshmallows
🔥 Pop under the broiler for 3–5 minutes until golden and gooey
🍓 Grab graham crackers, strawberries, apple slices… or honestly just a spoon

That’s it. That’s dessert.

Warm chocolate + toasted Chocolate Chip Marshmallows + approximately five minutes of effort = a VERY good little after-dinner treat.

Important question: are you dipping with a graham cracker, fruit, or going straight in with a spoon? 👀

Do you prefer it frozen or room temp?

We love our celiac community but we take other allergies just as seriously. Everyone should get to enjoy a sweet little treat.
