Strawberry Blueberry Crumb Bars

Easy Strawberry Blueberry Crumb Bars Recipe from A Kitchen Addiction

My berry hoarding from a couple weeks ago is still going strong! We were just at Costco a couple days ago, and I picked up another big container of strawberries.

They are just too good to pass up!

We’ve really been enjoying eating them in breakfasts like the blueberry banana bread baked oatmeal from last week, but sometimes you just need a dessert.

And, since it’s summer, you can’t go wrong with a fruit filled crumb bar! So, strawberry blueberry crumb bars have been our new quick and easy summer dessert.

If you’ve never made crumb bars before, you really should give them a try. They are super easy to make. You basically use the same mixture for both the crust and the topping.

I just added a little coarse sugar on top to give it a bit of a crunch.

And the filling? No boiling the fruit. Just stir all the filling ingredients together, and spread it over the top.

To bring out the flavor of the fresh berries a bit more, I threw in fresh lemon zest into the crust and tossed the berries with fresh lemon juice. The tartness of the lemon balances perfectly with the sweetness of the berries.

Top with the remaining crust mixture, sprinkle with sugar, and bake. Eat them warm, eat them cold. It’s good both ways.

Though if you have some vanilla ice cream on hand, I highly recommend eating at least one of the bars warm with a scoop of ice cream!
