    This Concord grape crisp with a peanut butter crumble topping is an ode to peanut butter and jelly and an easy dessert to bake with Concord grapes.

    What to bake with Concord grapes

    I'd made a fantastic Concord grape & rosemary focaccia, but still had the rest of a basket of Concord grapes to get through. I briefly considered baking a Concord grape pie, but I was feeling rather lazy, which is why fruit crumble desserts are so awesome. For this crumble, I thought it would be cool to transform my favourite sandwich, the classic peanut butter & jelly sandwich, into a super easy homemade treat. I am a HUGE fan of peanut butter and jelly. As a kid, I went through a phase where for breakfast, I'd make mini Eggo pb & j sandwiches, slapping thick layers of peanut butter and jam between two toasted mini Eggo waffles. Let's just say it wasn't my healthiest of phases, but they sure tasted amazing.

    Turning Concord grapes into fillings for pies and crumbles

    A Concord grape filling takes a little more time than the usual crumble fruit filling for several reasons:

    1. Concord grapes have seeds, so you can't just throw Concord grapes into any pie recipe. You've got to separate the seeds from the flesh/skin of the Concord grape, which means extra steps in any recipe with this fruit.
    2. Concord grapes are very juicy, so when you want to turn Concord grapes into a pie or crumble filling, you need to precook the filling to release the grape juice and thicken it before assembling your pies and crumbles

    The extra effort to prep Concord grape fillings is worth it here because this recipe makes a tart, jewel-toned jam layer that fits snuggly under a peanut buttery cookie topping. I like a generous amount of crumble on my fruit bakes and this peanut butter crumble topping recipe makes a double batch, enough to make this crumble and even a few cookies baked on the side for snacking on later. If you aren't a fan of peanut butter, you can always swap out this peanut butter crumble and opt for a honey oat crumble or even a chocolate crumble instead. I think a grape crumble would be great with any of these toppings.

    Peanut butter crumble topping

    You can make classic peanut butter cookies and chewy peanut butter cookies with white chocolate chunks, but peanut butter also pairs so well with many berries and fruits, so why not turn peanut butter into a peanut butter crumble topping with a few oats for added texture? You can use smooth or chunky peanut butter, but for this recipe, I opted for unsweetened peanut butter so that I could control how much sugar was going into the topping. If you use sweetened peanut butter, the results may differ.

    Equipment

    • Deep 7-in baking dish
    Need measurements in CUPSUse the button options below to switch from Metric to US measurements! It's that easy!

    Ingredients
     
     

    For Filling

    • 480 grams Concord grapes roughly 3¾ cups
    • 100 grams granulated sugar
    • 7.5 mL fresh lemon juice
    • 15 mL minute tapioca

    For the peanut butter crumble

    • 70 grams rolled oats (or large flake oats)
    • 45 grams bleached all-purpose flour
    • 50 grams light brown sugar
    • 60 grams all natural, unsweetened smooth peanut butter
    • 58 grams unsalted butter

    Instructions
     

    To make the filling

    • Rinse the grapes thoroughly and dry them.
    • Pinch grapes to push out the green flesh. Put the flesh into a medium saucepan, reserving the skins in a 7 inch round ramekin baking dish (like this one on Amazon).
    • Add sugar and lemon juice to the pan, and cook on medium-high heat to bring the mixture to a boil. Continue heating for 6 to 8 minutes, until the flesh breaks down and releases the tiny seeds.
    • Strain the mixture and push it through a sieve placed over the bowls of grape skins.
    • Let the mixture cool for 10 minutes, add the tapioca, and then let it sit for 1 hour to cool at room temperature.

    To make the peanut butter crumble

    • Preheat the oven to 350ºF.
    • Mix all the dry ingredients in a medium bowl, then work in the butter, followed by the peanut butter until the mixture resembles a coarse crumble (you can use your hands, a fork, or a pastry cutter for this step).
    • Crumble the mixture over the grape filling.
    • Bake the crumble for about 40 minutes, until the fruit filling is bubbling hot and the crumble is beginning to brown on the top.
    • Let the crumble cool about 30 minutes before serving. Serve warm or cold.

    Notes

    • For the tapioca, I used Kraft minute tapioca available on Amazon

        I did. I picked and seeded the wild grapes this fall during a vacation by the beach and then froze them. Just found them (6 months later) and chose this recipe. Seemed like the right thing on a cold, windy winter day. I did make one change to the recipe. Since my grapes were already seeded, and the prep of cooking on the stove would take time, I just mixed the frozen grapes, granulated sugar, lemon juice and tapioca (2 Tablespoons instead of 1) in the baking dish and then added the topping. Baked the same length of time and all was well.

      Can you make this in a 9 by 13 glass baking pan and line the bottom with the crumble and the top as well? How much.more ingredients would be required?

      Yuummmy!A bit sweet for me, but well balanced with the tartness of concord grapes.
      I quadrupled the recipe and froze the extra crumbles for a tasty treat through the winter.
