Feel free to add in nuts for some crunch - we like toasted pecans or walnuts.
You can also make this recipe with peanut butter chips, white chocolate chips, or butterscotch chips.
For a s'mores variation, add in 1/2 cup of dehydrated marshmallows.
These bars are thick and chewy and almost spongy, not dense and gooey like traditional chocolate chip cookie bars.
For best results, use a baking pan with squared-off edges as opposed to rounded ones.
This recipe can be doubled and baked in a 9x13-inch baking pan.
Using finer graham cracker crumbs will allow for more rise in the dough and lead to a thick and chewy, and almost spongy texture. If your crumbs are more roughly crushed, like in the process photos, you'll get more dense and gooey bars like traditional chocolate chip cookie bars. Both are delicious, it really depends on your personal preference.
