Ingredients

- Butter: I use Organic Valley Salted Butter, but you can use your favorite. It's melted in this recipe, which is nice because you can use it straight from the fridge.
- Light Brown Sugar: I use my homemade light brown sugar, but store bought also works.
- Dutch Cocoa Powder: I use organic Dutch cocoa powder which provides rich chocolate flavor to these bars.
- Strawberry Jam: I'm filling these with Organic Strawberry Jam With Fresh or Frozen Berries, you can use homemade or store bought in this strawberry bar recipe.
- Cornstarch: I add organic cornstarch mixed into the jam. This ensures that the jam solidifies in the oven as it cooks, preventing it from running out.

Baker's Tips for Chocolate Strawberry Crumb Bars
- Always use a digital food scale for the best results.
- I use melted butter in this recipe, which makes it super easy! You can melt the butter any way you like, whether you prefer stovetop or microwave.
- I use Dutch cocoa powder in this recipe as it’s sweeter and it’s my preferred cocoa for baking. If you only have natural cocoa powder, that will work, they may not be as sweet. But, if you prefer that, then natural cocoa powder is fine to use.
- This recipe for Chocolate Strawberry Crumb Bars uses strawberry jam. But if you want to switch it up, you totally can! You can use raspberry, blackberry, or blueberry – these would all be delicious with chocolate!
- The cornstarch is used to help thicken the jam so it won't leak out when the bars are cut. So, that's why it's a crucial part of this recipe. If you are avoiding corn, try Irish moss powder, potato starch, or tapioca starch in its place.
- This is a great recipe to bake ahead of time as they will stay good just out on the counter for a few days. So, if you need to bake dessert ahead of a party, this recipe is an awesome option!
- High Altitude — Bake the crust at 350°F for 12 minutes. Fill and add topping per the instructions, then bake again for 25 to 28 minutes, or until the topping is golden brown and dry.
How to Make Chocolate Strawberry Crumb Bars

- To make the crust and topping: In a medium bowl, add the flour, cocoa powder, cane sugar, and light brown sugar.

- Whisk together.

- Add in the melted butter and stir to combine completely.

- Reserve ½ cup for the topping and set aside.

- Using your hands, or a measuring cup, press the remaining crust into the bottom of the pan evenly.

- Bake the crust in the preheated oven for 15 minutes.

- To make the filling: In a small bowl, add the strawberry jam and cornstarch and stir together until combined.

- When the crust is done baking, remove from the oven. Add the strawberry filling on top.

- And sprinkle the remaining crumb topping on top.

- Return to the oven and bake for another 27 to 30 minutes, or until the topping looks dry. Allow to cool in the pan completely.

- To make the glaze: In a small bowl, add the powdered sugar and water and whisk until you have a smooth glaze.

- Drizzle the glaze over the top of the bars.

- Cut into 9 bars.
Recipe FAQ's
Crumb bars are a shortbread base so they are buttery and crisp. This is why we don't use baking soda or baking powder as these are a denser cookie bar. The combination of the dense shortbread crust, jammy filling and crumbly mixture on top makes these so delicious!
Yes! You can use raspberry, blueberry, or any other flavor you think would be delicious with chocolate!
Yes! All of my recipes have a simple high altitude adjustment in the Notes at the bottom of the recipe. So, if you are baking above 5,000 feet the be sure to check that note.
If you didn't partially bake the crust, the bars can be soggy. If you also don't put cornstarch in the jam, it can cause the bars to become soggy as the cornstarch solidifies the filling. So, don't skip the cornstarch. If you are avoiding corn or don't want to use cornstarch, use tapioca, arrowroot or potato starch in its place.
If you skipped the cornstarch, this will happen. This is important to solidify the filling. If you don't want to use cornstarch, use tapioca, arrowroot or potato starch instead.
Under baking. Crumb bars should be crispy, so ensure you are baking until done.
When the crumble topping looks dry and crispy.
If you don't let them cool completely, they will crumble when slicing. Make sure to let bars cool all the way before cutting.
Crumb bars are made up of a shortbread crust and crumble topping. Both of which need to be kept in a cool dry place to retain the buttery, crisp texture. So these are best stored out on the counter. Don't put these in a tupperware or cake dome as it could make them soggy or mushy.
Because the jam is baked, I don't usually store these in the fridge as we usually eat them within a couple days! If you are going to keep them longer than a few days, I recommend keeping in the fridge.
