This week I’ve shared how to have a farm to table dinner in your backyard along with recipes for a salad with homemade buttermilk ranch dressing and soft boiled eggs, ginger glazed and seared carrots, potato and kohlrabi salad, rotisserie chicken, and now these 5 ingredient jam crumb bars. These bars are so delicious and versatile and will feed a crowd!

I just love desserts like that – desserts that feed a crowd. Because honestly, sometimes when there’s a whole group of people the last thing one wants to do is ‘chance it’ and try doubling or tripling a recipe without knowing what the end result will be.

And they’re beyond easy to make, only five ingredients (perfect for Five Ingredient Fridays) and can be customized to whatever jam you have on hand or want to use. If you have some fruit (another idea for what to do with leftover fruit) you most certainly can add it in. I like to use a big baking sheet – a jelly roll pan (like this 12 x 18 jelly roll cookie sheet) for baking.

Jam bars - a dessert that feeds a crowd

When I made these bars for the farm to table dinner I added some fresh strawberry slices, but that is totally optional, you really just need some good quality jam and you’re all set to go. I’ve found that the best jam for these bars is a berry jam that has a little bit of tartness to it…perhaps a berry blend or a seedless raspberry.

The flavor combination is really great – the butter and ‘crumb’ topping is the perfect texture and flavor contrast to the jam. I would say these are perfect for summer, but the truth is, these would be great for any season or occasion-birthdays, holidays, potlucks, you name it…these jam crumb bars would make a great addition (I’m thinking of making these with cranberries for Thanksgiving).

5 Ingredient Jam Crumb Bars
Prep Time 10 minutes
Cook Time 25 minutes
Total Time 35 minutes

Ingredients

  • 3 sticks butter (1 1/2 cups butter)
  • 2 cups flour
  • 1 cup oats
  • 1 cup sugar
  • 2 cups jam
  • (optional - fresh fruit-such as a pint of strawberries)

Instructions

  • Preheat oven to 375, use a little of the butter to grease a jelly roll pan.
  • In a food processor pulsate together 1 cup of the butter (cut into chunks before adding to the food processor), 1 2/3 cups flour, 2/3 cup of the sugar and 1/3 cup oats. Pulsate until combined into a mealy mixture. Press into the prepared pan.
  • Spread the jam over the prepared layer. (If adding fruit - now is when you would add it)
  • In the food processor process the remaining ingredients (1/2 cup butter, 1/3 cup flour, 1/3 cup sugar, 2/3 cup oats) until a crumbly mixture, then sprinkle over jam.
  • Bake for 25 minutes or until edges are golden brown, then remove from oven and allow to completely cool before cutting into squares (I cut big squares and got 32, but you could easily cut these into small squares for more!)

      These bars are ah-mazing! Only 5 ingredients, simple to whip together, feed a crowd AND seriously delicious?! I am SO all over this! I love how soft and scrumptious the crumb topping looks and your addition of sliced fresh strawberries (i’m taking your suggestion and adding these for sure!)! These bars just look and sound like the jam (<– pun totally intended). Cheers and thanks for sharing the YUM! 😉

        Hahaha, I totally love puns and had to stop myself from saying ‘these are my jam’ like 500 times lol! Thank you for commenting, I definitely think you’d love them with the fresh strawberries.

      Phi, these are gorgeous! I’ve loved reading these farm-to-table posts. They’ve inspired me to have a summer picnic. These bars will definitely be coming too–I have some raspberry jam that would be perfect!

        I don’t know why I never even thought of them with a cup of coffee, but you’re absolutely right, these would make an awesome coffee-cake-like dessert – they’d be great for breakfast, an afternoon snack or dessert! Thanks for the great idea, love you!

      Easy, no fuss dessert/snack. Really great work Phi!
      Indeed a fantastic crowd pleaser! We don’t have any of our homemade jam left, but we recently bought an IKEA raspberry-blueberry jam that’s really good. It seems like the obvious choice for this recipe!:)
      Thank you for another delicious treat dear!
      Lots of greetings,
      Panos and Mirella
