Make no mistake, these are mammoth cookies – thick chunks of oaty goodness sandwiched together with a creamy white chocolate and peanut butter filling.
They were so chunky that I did reconsider making them single layer and spreading the filling over the top instead, but my kids set me straight and said they were perfect as they are! This is probably because the cookies themselves are not overly sweet, making them a nice contrast to the rich filling.
The measurements below made four heart cookie sandwiches (so that’s 8 cookies in total). You could easily roll them out a little thinner, make them a touch smaller or forego the double cookie sandwich completely and just have the filling on top.
