I made these Blueberry Streusel Bars with Lemon-Cream Filling for an office birthday celebration. It was the first time I had made the recipe, but it was in my files with a note that it is one of my daughter Lisa's favorites, and I almost always like her recommendations. It also seemed like a good summer treat, pretty easy to make, and good for a group. I was a little nervous about how they would turn out, but I shouldn't have worried - everyone seemed to enjoy them.
When you make them use fresh blueberries and lemons, and make sure the blueberries are at room temperature. You can multiply the recipe as long as the pan size increases proportionately.
Great dessert for that summer barbecue!
