Made With The Sweetest Berries Of Summer

Blackberry Crumb Bars sound like something Ma Ingalls might have baked in her summer kitchen in the Little House On The Prairie. Can you picture happy barefoot kids swinging their berry-picking buckets as they skip onto the front porch with telltale purple stains all over their faces?

Blackberries grow on prickly bushes called brambles and ripen in mid to late summer, but depending on where in the United States you live, ripe blackberries can be found from May through September. They are the sweetest berries of summer and undoubtedly the most jewel-like and beautiful. But blackberries are more than just a pretty face!

The dark color of the glossy berries reveals they are super healthy with the highest antioxidant level of any food. They are also high in fiber and vitamins C, E, and K! They contain anthocyanins. This powerful phytonutrient protects the brain from stress and may reduce the effect of age-related conditions.

Let’s Bake Blackberry Crumb Bars With Fresh Blackberries

We will start with the buttery sweet crust. Melt the butter and whisk in the brown sugar and lemon zest.

Add flour, baking soda, salt, and cinnamon to the butter mixture until well incorporated.

Then set aside one cup of the crust mixture you will use as the topping.

Press the remaining dough evenly into an eight-inch baking dish lined with parchment paper and bake it at 350 degrees for about twelve to fifteen minutes or until it is a lovely golden brown color. Let the crust cool completely while you make the yummy blackberry filling.

Wash and dry the blackberries, cut them in half, put them in a medium mixing bowl with the flour, sugar, and lemon juice, and mix them all together. Spread the blackberry mixture evenly to the edge of the crust.

Now crumble the crust mixture you set aside over the blackberry filling and bake the bars in that 350-degree oven for about forty minutes.

Let the bars cool completely before cutting them into ten rectangular bars.

These beautiful old-fashioned blackberry crumb bars are not overly sweet and would make a wonderful treat for breakfast! They are sweet enough, though, that they make a wonderfully light dessert. I can’t imagine how delicious they would be with a scoop of lemon sherbet!

This recipe is so nostalgic and would taste best when eaten on a porch swing after supper as the fireflies are beginning to peek out! Ma Ingalls would surely agree this treat is summer perfection.
