S’mores Jar Cake for One

by Erin

Love s’mores but don’t want to share? Make this single serving s’more jar cake! Also ships well as a fun treat in the mail to a loved one.

S'mores Jar Cake 1
It’s time for me to give you a dessert for Single Serving Sunday, because in all honestly leftover desserts are my downfall. Leftover entrees are dispersed throughout the week as lunches or dinner on subsequent days (even though I may get bored of it sometimes), but desserts either have to be passed out at work or frozen. There are so many more servings in a batch of cookies than a pizza! So single singer desserts are really what I should focus on more.

Jar desserts are pretty popular in the summer-time, especially for bringing to picnics because they are easy to transport and hand out as individual portions. However, most recipes make multiple single servings. But this s’mores jar cake recipe only requires one 16 oz jar. Granted you probably could say it serves 2, but do you really think you will want to share this with anyone? Let’s be honest with ourselves.

Jar cakes are also great when you want to ship a treat for someone’s birthday, which is exactly what I did. To make it prettier, I topped the jar lid with a cupcake liner – something I probably saw on Pinterest once. I thought it was really cute.

S'mores Jar Cake 2

Two years ago: Skillet Chicken with Peppers and Peanuts


Makes one 16 oz. jar cake



1/3 cup graham cracker crumbs

1 Tbsp unsalted butter, melted

Pinch salt


1/4 cup all-purpose flour

1 Tbsp cocoa powder

1/4 cup sugar

1/4 tsp salt

1/4 tsp baking soda

1 egg

2 Tbsp canola or vegetable oil

1/4 tsp vanilla extract

1/4 cup semi sweet chocolate chips, melted


4-5 large marshmallows


  1. Preheat oven to 350 degrees. Spray mason jar with non-stick spray.
  2. In a small bowl, combine butter, graham crumbs and salt. Mix until moistened. Press graham crust into jar. (I pressed the crumbs down firmly with the back of a cookie scoop.)
  3. Place flour, cocoa, sugar, salt, baking soda, egg, oil, vanilla and melted chocolate into a medium mixing bowl. Mix all ingredients until well combined.
  4. Pour batter into prepared jar, place in a small baking dish and add about enough water to cover the bottom inch and bake for 25-30 minutes or until baked through.
  5. Remove cake from the oven and press large marshmallows down on top. Heat the broiler and brown marshmallows for about 1-2 minutes, or until golden brown.

I’ve never made a jar cake, I’m so late to jump on the bandwagon! But if I did make one, it would have to be s’mores and you’re right, I wouldn’t share it with anyone :)

Jar cakes are so cute, but doing S’mores is a stroke of genius!

Even though I bring most of my dessert leftovers to lab, there are some times I just want to make something all for myself or not have to make a huge batch of it. WIN for the s’mores jar cake!
