Welcome to an easy new way to enjoy apple pie. Powered by convenient store-bought piecrusts and packed with two types of apples and a warm melange of cozy spices, this streusel-topped pie is a fall dream. But walnuts are what makes this recipe twist extra special. With their classic buttery richness and just a hint of toasty bitterness, they provide a sturdy flavor backbone to hold up to the sweetness and balance the tartness of the filling. It slices best at room temperature, so try to make yourself wait if you can bear it. Although it is delicious with a scoop of Black Walnut Ice Cream melting into the streusel.
