S’mores Brownies in Jars

This s’mores inspired dessert, S’mores Brownies in Jars, was a snap to prepare. A layer of graham cracker crust was topped with some fudgy brownie dough and baked in cute little mason jars.

Marshmallows filled the rest of the jars and were broiled to give that characteristic roasted s’mores look. You can also make these using a boxed brownie mix, which will most likely fill more than 4 jars.

S’mores Desserts

We spent many summer vacations with my in-laws up in Wisconsin. Boating, fishing, Packer worshiping were all part of our adventures up north. Come sundown, we’d get a roaring campfire going and spend the last minutes of twilight searching for the perfect marshmallow roasting sticks.

Making s’mores by squeezing a charred and gooey marshmallow and a piece of milk chocolate between two graham crackers was part of our nightly routine. But even better than traditional campfire s’mores are s’mores desserts like these layered brownies.

Is It Safe to Bake in Mason Jars?

Mason jars are made for canning, so they can tolerate temperatures. Buy a good quality canning jar to ensure they stand up to baking.

How to Store Mason Jar Desserts

Thankfully, these desserts in jars are self-sealing, so it’s easy to store the leftovers. Just screw on the caps and store them in the refrigerator for up to 3 days or the freezer for up to 3 months.  Bring to room temperature then gently warm if desired to soften the marshmallows.

What is Jarcuterie?

A new fad with the global pandemic in full swing is to serve appetizers in jars, like cheese sticks, crackers, and cured meat. It’s much safer than hovering around a cheeseboard with many hands reaching in to grab a nibble. Other ideas include veggie sticks and dip, cheese puffs, or anything on skewers! Jarcuterie is a term that comes from blending charcuterie, AKA a cheeseboard, with jars.
