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.

Recipes from the Heart

When I learned that my father-in-law had metastatic lung cancer earlier this year, Kim of Cravings of a Lunatic was the first blogger friend to reach out and offer me comfort and an ear whenever I needed to talk. She watched her own father succumb to this vicious disease and knew how it ripped her heart to shreds. She approached me earlier this spring about sharing a dish for “Recipes from The Heart” to honor her dear dad.

Scroll down to see all the wonderful dishes and links, including my S’mores Brownies in Jars, to stories about how cancer has affected so many of us. And I’m certain you’ll want to enter our KitchenAid Stand Mixer giveaway, too.

Recipes from the Heart Event Details:

Today’s event is being hosted by Kim and Jen of Juanita’s Cocina. They teamed up with a group of blogger friends to help raise awareness and support for Cancer and Hospice today in memory of Kim’s dad. We encourage everyone to read the posts and share their own experiences with cancer.

We also would like to encourage everyone to donate to the Canadian Cancer Society, the American Cancer Society and also to the Canadian Hospice Palliative Care Association. Hospice was a key element during Kim’s father’s battle with cancer. They made it possible for Kim to care for him at home. So please show your support and donate if you can. You can also contact your local Hospice and donate directly to them if you wish. A little goes a long way!

  1. It’s been so sad to read about how cancer has affected you, Kim, and countless others, Liz. I hope that writing these posts have been cathartic. I know that your words are providing invaluable comfort to others who are going through it right now. I’ve known many wonderful people who were taken too soon by cancer, but I’ve been lucky enough that it hasn’t been anyone as close to me as a parent or sibling. I think this is another lovely tribute to your dear FIL and your s’mores in a jar look ooey gooey delicious!

  2. Lovely post, Liz. I love s’mores brownies & even better when you get your own jar!

  3. Brian’s mother is, amazingly, a two time lung cancer survivor. My life-long best friend, however, lost her mother to lung cancer last year. Neither of these women smoked and it strikes a sour note with me when I hear people make that assumption. Somehow lung cancer becomes the victim’s fault! Anyway, sorry to get on the soap box. I know you loved your FIL and I’m deeply sorry for your family’s loss. I think remembering him over these delicious looking treat jars would be wonderful!

  11. Our Father’s Day here is in September and I always try to zone it out because my father too died of cancer. This is a lovely event and Kim is a very special lady as are you, Liz. Your pain is still very fresh while mine is six years old but you never forget, it just gets easier.
