Preheat the oven to 350°F and line a few sheet pans with parchment paper or silicone baking mats.
Use a food processor or small food chopper to chop the pepperoni into tiny pieces.
Use a stand mixer or hand mixer to combine the cream cheese, chopped pepperoni, sausage, garlic powder, and Italian seasoning. Add the baking mix and mix to combine. Add the cheese and mix to combine.
Roll the dough into 1 1/2-inch balls and place them about 2 inches apart on the baking sheets. I like to use a cookie scoop to keep them uniform.
Bake for 20 to 25 minutes or until golden brown. Serve alongside some warm pizza sauce for dipping.
