Pastries cut into bar-shaped pieces never really go out of style. When one food magazine writes a story about bars, every other food magazine fires back with its own take on these simple-yet-delicious bites of happiness. With a handful of recipes for crusts and toppings, you can easily make bar cookies completely interchangeable.
If you find a crust that you like, let’s say a shortbread crust, play around with the topping. Perhaps make a pecan, Key lime or lemon filling, or even a fudgy brownie bar, with an oatmeal brown butter crust.
