Blackberry lemon crumble bars make the perfect dessert to bring to any potluck or barbecue this season.  Simply because you can serve them chilled or at room temperature.  But they taste their best at room temperature.

Oh, and no need for a fork or spoon either when serving these bars – only a napkin will do!

Crumble bars recipes like this one are very simple to make and require only a few ingredients such as: butter, sugar, baking powder, flour, salt, egg, one large lemon and of course, fresh blackberries.  It uses the same buttery crumble mixture for both the crust and the topping, making this dessert a quick and easy 2-step recipe.

OK…  then – lets get started!!

For this recipe, I bought two 6-ounce containers of blackberries and only used 1 and half, which is about 2.5 cups.

I usually use my pastry cutter to make the crumbs, but if you don’t have one you – no worries, you can use your hands to make the crumble mixture as I have done here.

How to make these easy Blackberry Lemon Crumble Bars!

First, slice blackberries in half or into thirds and toss them into a small bowl.  This will allow their juices to come through and give these blackberry bars even more depth of flavor.

Then mix blackberries with lemon juice, some sugar and cornstarch and set them aside.

Meanwhile, in a large mixing bowl, make the crumble mixture.  Then pat about half the crumbs on the bottom of your baking dish.

Next, pour the blackberry mixture on top of the crust in an even layer.  Then top with the remaining crumbs on top of the blackberries (photo is not shown).  Then bake for about 25 to 30 minutes or so.

A Cook’s Tips and Notes:

  • We recommend to put on an apron when cutting the blackberries, to prevent staining your clothing.

  • What if we don’t have cornstarch?  You can substitute with flour instead, this will help thicken the berries mixture.

  • Can I use salted butter instead of unsalted?  Yes, but omit the 4th ingredient (1/4 tsp. salt) from the recipe.

  • What if we don’t have vanilla extract?  Don’t worry I have made these bars without it, and it’s fine.

  • Always allow this dessert to cool completely before cutting into bars.  If too warm, they will fall apart.


We love crumble bars, don’t you?

We hope you’ll try our other flavors!   Lemon Blueberry Crumble Bars, and our Raspberry Lemon Crumble Bars -they too are scrumptiously delicious!
