I'm not much of a fan of Peach and Blackberries so I'm going to try this with Apple Preserves and Cranberry Jel. My other variation thoughts are Strawberry Preserves and Orange Marmalade. Any combination would seem to work as long as the main fruit is a peserve (without fruit chunks) in it.
I received these fabulous cookies as a gift this weekend. Couldn't believe how wonderful they are. Am making them right now for my neighbor. I particularly love the browned crust around the edges. Try this fantastic recipe.
I have made these bars for several church functions. They disappear quickly. I love the sweetness from the peach and the slight tartness of the raspberry. And, the shortbread bottom melts in your mouth. Found it was easiest to make the shortbread in the food processor. So quick!
