Strawberry Bars

My Strawberry Bars are such a fun treat to bring to friends and family! They have a buttery shortbread crust, strawberry jam filling, and a homemade oat topping that turns golden and crisp in the oven. Serve them at brunch, pack them in a lunchbox, or just enjoy them with coffee in the afternoon.

I've been making these jam bars over and over again since early spring. The minute the weather starts warming up I start craving fruity desserts! Pineapple upside-down cake, lemon meringue pie, peach cobbler... you name it, I just can't get enough!

And these bars are no different. There's just something about the contrast of buttery, crumbly shortbread and sweet strawberries! It calls to me. Give these a try, and you'll see what I mean.

Here's Why You'll Love This Recipe

  • You only need basic pantry ingredients for these strawberry bars, and they take about an hour to make.
  • The shortbread crust is rich and buttery, and the crumb topping adds a nice texture to the bars.
  • The strawberry jam layer makes the bars sweet and fruity, and you do not need to cook fresh berries.
  • These bars work well for breakfast, brunch, dessert, or as a snack.
  • You can easily customize them with other jams, citrus zest, nuts, or spices.

Ingredients You'll Need

The recipe card at the bottom of the post contains the full list with all of the amounts. Refer to that when you're cooking.

For the Shortbread Crust

  • All-purpose flour: Gives the crust structure and helps create that classic tender shortbread texture.
  • Powdered sugar: Sweetens the crust while keeping it soft and delicate.
  • Kosher salt: Balances the sweetness and brings out the buttery flavor.
  • Unsalted butter: Use cold butter so it can be cut into the dry ingredients, creating a crumbly mixture that bakes into a rich shortbread base.

For the Strawberry Filling

  • Strawberry jam: This is the sweet, fruity center of the bars. Use your favorite store-bought or homemade jam. Add more if you want a thicker layer of fruit.

For the Crumb Topping

  • Unsalted butter: Melted butter helps the crumb topping come together quickly and adds rich flavor.
  • All-purpose flour: Forms the base of the crumble and helps the topping bake up tender and crumbly.
  • Granulated sugar: Sweetens the topping and helps it turn a light golden color.
  • Old-fashioned oats: Add texture and a rustic, chewy bite. Avoid instant oats, which can become too soft.
  • Lemon zest: This brightens the strawberry flavor and adds freshness.
  • Kosher salt: Keeps the topping from tasting too sweet.
  • Powdered sugar: Optional, but a dusting on top makes the bars look nice.

Step 1: Make the Shortbread Crust

Preheat your oven to 350 degrees F.

Lightly mist a 9x9-inch baking pan with non-stick spray, then line it with parchment paper. Leave a little overhang on the sides so the bars are easy to lift out later.

In a large bowl, stir together the flour, powdered sugar, and salt.

Add the cold butter and cut it in until the pieces are about the size of peas. The mixture will look crumbly but should hold together a bit when pressed.

Make sure your butter is COLD. This way the shortbread will come out so, so tender.

I use a pastry blender to cut in. It's great for making just about any kind of pastry. Besides shortbread, I also use it for pie crust, biscuits, scones, puff pastry... even for croissants, if you can believe it.

If you don't have one, here's a link: Pastry Blender. Only a few dollars, and you'll definitely get a lot of use out of it if you like to bake.

Or, you can use 2 knives, or just rub the butter in with your fingertips.

Transfer the crust mixture to the prepared pan and press it into an even layer.

Par-bake the crust for about 20 minutes.

Step 2: Add the Strawberry Filling

Spread the strawberry jam in a thin, even layer over the partially baked crust.

If you really want to dazzle, try using homemade strawberry jam. You only need 3 simple ingredients, and it tastes like nothing else! Check out my old standby recipe: Strawberry Jam. I've been making it every summer for years!

But store-bought works great. And it doesn't have to be strawberry! Use any kind of jam you like.

Here are a few ideas:

It is fine if the crust is still hot when you add the jam.

Use a small spatula or the back of a spoon to gently spread the jam, taking care not to break the shortbread layer.

Step 3: Make the Crumb Topping

This topping is just a variation on my Basic Streusel Recipe.

In a bowl, stir together the melted butter, flour, granulated sugar, oats, lemon zest, and salt.

Mix with a fork until the topping looks crumbly.

Step 4: Bake

Bake for 30 to 40 minutes, until the topping starts to turn golden.

Let the bars cool completely before cutting. This helps the jam set and makes it easier to get neat squares.

If you like, dust the bars with powdered sugar.

Helpful Tips and Tricks

  • Use cold butter for the shortbread crust. It helps make the crust tender and crumbly.
  • Do not skip the par-bake. It keeps the bottom crust from becoming soggy under the jam.
  • Let the bars cool before cutting. If the jam is still warm, it will be too soft and messy.
  • Line your pan with parchment paper so you can lift out the bars before slicing.
  • Use a sharp knife and wipe it clean between cuts for neat squares.

Easy Recipe Variations

  • You can use raspberry, blueberry, apricot, blackberry, or peach jam instead of strawberry.
  • Add a pinch of cinnamon to the crumb topping for extra warmth.
  • Mix in chopped pecans, walnuts, or almonds to the topping for more crunch.
  • Try orange zest instead of lemon zest for a sweeter citrus flavor.
  • For more fruit texture, add a thin layer of sliced strawberries over the jam.

Recipe FAQ

Can these be made gluten-free?

I have not tested it a gluten-free version myself, so I can't guarantee the results, but if you'd like to try making a gluten-free version, use a gluten-free flour blend that subs 1:1 for regular flour.

Here are a few good options:

I'd love to hear about your results! Drop a comment below; I'm sure it will be helpful to other readers.

And if you'd like to make this dairy-free and vegan, use a dairy-free butter product that subs 1:1 for regular dairy.

Can you use fresh strawberries?

I've tried adding fresh sliced strawberries to the filling, and while it looks gorgeous and tastes incredible, it will make the bars a little soggy. Personally, I would leave them out.

But if you absolutely must, use them sparingly, and err on the side of slightly overbaking to help evaporate out some of the excess moisture.

Can this recipe be made in a different sized pan?

If you need to feed a crowd, double this recipe and it can be made in a 9x13 pan.

I will also add that the bars you see in the images and videos here are pretty large, at about 3-inches square. And that is reflected in the nutritional info. It looks great but personally, I can only eat about half a bar in one sitting.

How do you store this recipe?

These keep really well at room temperature, for quite a while! Just keep them in a zip-top bag and they should be good for at least a week!

Or you can freeze them. They should last for a few months in the freezer. Thaw them at room temperature or in the microwave for about a minute or two on a low setting.

  1. This is just such a great recipe. I can remember when I was young that my mom would make similar bar to this and they would not last any amount of time in our house. I have some really great strawberry jam just begging to turn into these squares, and yes, they will be made into a 9x13 inch pan!

    1. Yes, that should work! But keep a close eye on them as they bake. The bake time may need to be adjusted. Good luck!
