Strawberry Jam Bars

Strawberry jam bars are all about that unbeatable combo of buttery shortbread cookie dough and sweet-tart strawberry jam. This simple dessert never disappoints!

strawberry jam bars are like a portable strawberry crumble!

I love the versatility of a shortbread crumble bar, I’ve made them with raw fresh fruit, cooked fresh fruit, fruit curd, and all sorts of jams and preserves. This one’s all about the sweet taste of summer berries, complemented by a very lightly spiced, brown sugar and oat shortbread crumble. There’s no frills here, no fuss, just a comforting, portable little bar perfect for tucking into a lunchbox, working lunches, long flights, and picnics.

the star of these cookie bars is a homemade strawberry jam

But the beauty of this recipe is that it will work with any kind of jam you have — just make sure you love the flavor because it’s the main driver of this recipe.

  • Strawberry jams tend to be on the sweet side, which will make a nice sweet crumble bar that’s kid friendly. If you’re looking for a little bit more of a sophisticated taste, try a tarter jam, or even a marmalade which has a nice balance of sweet and bitter flavors.
  • If you have a jam you’d like to use that you feel is a bit too sweet, try mixing in a tablespoon or so of lemon juice before using it in this recipe. The kick of tartness really helps wake up the flavors.

the easiest way to make a shortbread crumble

I love to use my food processor to make shortbread dough — it’s so easy, quick, and virtually mess-free. Here’s how to do it:

  • Add your flour, sugar, and any other dry ingredients like spices, etc., to the bowl of the food processor. Pulse briefly to combine.
  • Add your room temperature butter, cut into chunks, and continue to pulse until the dough just comes together, like you see in the photo above. That’s it!

jam bar faqs

Can I use fresh fruit instead of jam?

Yes, you can use fruit like berries or peaches and use instead of the jam. Small berries can be used whole, larger berries and fruit like peaches need to be chopped or sliced.

How should I store jam bars?

These can be stored, loosely covered, on the counter. The crumble tends to soften as it sits, so sometimes I won’t cover them at all if it’s just overnight.

Can I add nuts to the crumble topping?

Yes, just fold in sliced almonds, chopped walnuts, or whatever you like. You can use them in place of the oats.

Can I use dark brown sugar?

Yes, you’ll get a nice boost of flavor with dark brown sugar.

Can I use a gluten free baking mix in place of the flour?

I’ve made my shortbread with a good gf baking mix and it does work, but be aware that the texture will be quite soft. (I like King Arthur Flour’s gf measure for measure flour.)

Would whole wheat flour work?

Yes, you can do all whole wheat, white whole wheat (my choice) or half whole wheat and half white flour.

Cook’s notes

  • If you don’t have a 7×11 pan you can use a 9 inch square baking pan or a round 9 inch tart pan.
