I made things easy though and used my favorite ONE INGREDIENT donut as the base! Yep. Just one ingredient...and it's not flour or yeast or anything like that. It's just refrigerated biscuit dough!
Heat oil in a deep skillet to 375 degrees. Place graham cracker crumbs in a shallow bowl.
Use a donut cutter or the lid from a 2-liter or 20 ounce bottle to cut holes in the center of each biscuit.
Fry the biscuits for 5-6 minutes, flipping over halfway through cooking, until golden brown on each side and cooked through. Drain donuts on a paper towel lined plate.
Continue frying donuts in batches until all are cooked.
As the donuts become cool enough to handle, roll them in the graham cracker crumbs. Spread a couple of teaspoons of marshmallow creme and Nutella on top of each donut.
