Bread in a jar is so 2010. And cake in a jar? Hello 1908. But brownies in a jar? Now you’re speaking my language.

I figured that if bread, cake and even cookies can squeeze themselves into canning jars, then who’s to say that brownies can’t share in the confectionery claustrophobia?

This unique baking technique seems to be sweeping the food blogosphere. First it was “_____ On a Stick,” and now it’s “_____ In a Jar.” But by far the best part of baking anything in a jar is that there’s an excuse for an ice cream topper, which creates a swirl of creamy vanilla bean and fudgy chocolate, all in a convenient cup. I’d say that beats pickled anything.

The next big craze? I’d like to be the first to guess that “Frozen _____ In an Ice Cube Tray” is about to hit it big. I wish I was kidding. I do it to my pesto. Friends do it to their chicken stock. Dessert cubes are a natural progression.

  1. I was also wondering this. Did you ever find out or am I going to be left guessing the size and burning the brownies?

      1. Yes, but it’ll affect the thickness of the batter so you may have to adjust the bake time.

  2. Hi, i have a lot of gerber jars from my baby.. I was wondering if I could use them.. And also I was worried about the glass to break at that temperature in the oven.. I have never made those of desserts and they look wonderful..
    Btw I am from Ecuador, I am following you since yesterday, today I made your chocolate chip cookies recipe with cream cheese with all your tips, the cookies were delicious and perfect shape!! Thank you!!

    1. Hi there! I’m not sure if that would work or if the glass is too thin to withstand the heat. I have never tried this recipe with baby food jars so I can’t say with certainty.

  3. if i seal them, how long will they be good???? I’d like to send my husband some. but shipping might take 2 to 3 weeks… please help!!!

  4. bingo! we’re so totally thinking alike. I love Ball jars. I have made pate’ in them for appetizer. I use them as water glasses (with sliced cucumber). And I use them for dessert during picnics (see my mango-coconut custard trifle with lime syrup…in a jar: http://bit.ly/k4wH1p)

  5. Such a simple, elegant, and fun entertaining idea! Love the thought of using Mason/Ball jars. They’re relatively inexpensive, and give the recipe a rustic/chic look. Definitely making this recipe @ home!

  6. i need to find some jars so i can make these!

    and you’re totally onto something with that dessert idea :)
