Red White and Blueberry Crumble Bars


An easy Fourth of July dessert

Here’s a red, white and blue version of a simple berry-crumble bar. I found this recipe years ago on, using blueberries. The notes said that any berry would work, so I thought why not strawberry? Better yet, why not both? You get red, white and blueberry crumble bars!

By making this half blueberry and half strawberry, you create red, white and blue all in one 9×13 pan. (I’m counting the neutral-colored crust as white here)

Some blueberry factoids

Did you know? In 2018, Oregon produced the most cultivated blueberries, recording 131 million pounds (60 million kg), an amount slightly exceeding the production by the state of Washington. In descending order of production volume for 2017, other major producers were Georgia, Michigan, New Jersey, California and North Carolina. Hammonton, New Jersey claims to be the “Blueberry Capital of the World”. Over 80% of New Jersey’s cultivated blueberries come from this town. Every year the town hosts a large festival that draws thousands of people to celebrate the fruit. Maine accounts for 10% of all blueberries grown in North America with 44,000 hectares (110,000 acres) farmed. However, Maine harvests only half of this acreage each year due to variations in pruning practices. The wild blueberry is the official fruit of Maine. (Source: Wikipedia)

How to make this patriotic dessert

Simply mix up the dough ingredients, then pat half of it into a 9×13 pan.

Strawberry and blueberry

Mix the berries with some sugar and cornstarch and then add to the pan.

Sprinkle the rest of the dough over the top before baking.

Red white and blueberry crumble bars

These Red white and blueberry crumble bars could be served warm with some vanilla ice cream to take it over the top, but I actually like these just as-is. And it totally gets full credit for the patriotic colors!
