This S'mores Smoothie captures the nostalgic campfire treat in a creamy, drinkable form that makes mornings or snacks feel like a cozy adventure. It blends the sweetness of marshmallows, the richness of cocoa, and the comforting crunch of graham crackers all in one simple blender cup.
I first whipped this up for a lazy weekend breakfast when I craved s'mores but wanted something cool and easy. It quickly became my go-to treat for whenever I want that campfire nostalgia without the mess.

I love how the combination of frozen bananas and marshmallow fluff creates a perfectly smooth texture that reminds me of summer camping trips with family. The graham crackers bring back great memories of toasting marshmallows under the night sky.
Best Storage Practices
This smoothie is best enjoyed fresh because the marshmallow fluff can settle and the graham crackers may lose their crunch. If you need to store it put it in an airtight container in the refrigerator and consume within 24 hours. Give it a good stir before drinking.
Ingredient Swaps
Try almond milk or coconut milk for different subtle flavors. Using chocolate almond milk will deepen the cocoa taste. Add a teaspoon of nut butter to enhance creaminess and add protein. Substitute crushed digestive biscuits if you cannot find graham crackers.
Serving Pairings
Serve this smoothie alongside a small bowl of fresh berries or a handful of nuts to add some contrasting textures. It also pairs well with simple toast or cereal for a fuller breakfast. Garnishing with a few marshmallow crumbs or a pinch of cinnamon adds a little extra fun.

This smoothie brings the nostalgic campfire treat into an easy and wholesome form that anyone can enjoy at any time.
