Blueberry Crumb Bars

I love blueberries – and now’s the time to stock up.  I buy them, put them on a sheet pan and freeze them individually, so they don’t end up in a big clump. I store them in the freezer and can easily get a handful for a recipe, or just to add to my oatmeal.

Here’s a recipe from for Blueberry Crumb bars, that uses fresh or frozen berries. These bars would be a great dessert to take to your July Fourth picnic or barbecue – no plate or fork needed.
