Preheat oven to 350 degrees F. Coat a bundt pan or round baking dish with cooking spray.
In four batches, stack 4 biscuits, each with sauce, pepperoni and cheese on top. Place all biscuits in a ring, filling up entire pan. Top with any remaining cheese.
Bake in the preheated oven for 40-45 minutes, or until biscuits are baked through. Serve with marinara sauce for dipping.
Notes
Replace pepperoni with sausage, bacon or Canadian bacon! Or omit the meat altogether and add extra cheese.
Other pizza toppings you could squeeze into the sliders: olives, green onions, chopped yellow onion, green peppers, jalapeno peppers or mushrooms.
Serve immediately after pulling out of the oven for optimal cheesy enjoyment!
