Preheat oven to 350 degrees F. Spray two rimmed baking sheets with cooking spray.

In a large mixing bowl, add 1 pound breakfast sausage (uncooked), 2 to 3 finely diced jalapenos, 1 pound shredded sharp cheddar cheese, 2 1/2 cups Bisquick baking mix, and 2 tablespoons milk.

Use an electric mixer on low to medium speed to combine the ingredients until evenly mixed, scraping the bowl as needed. (You can mix with a sturdy wooden spoon, but it will require more effort.)

Shape the mixture into balls a little smaller than a golf ball. Use a small cookie scoop if you have one, or form by hand. Place the balls on the prepared baking sheets in a single layer, spaced evenly.

Bake in the preheated oven for 20 to 24 minutes, until the tops are golden brown and the sausage is cooked through.

Let the sausage balls rest a few minutes on the baking sheets, then serve warm. Offer ranch or blue cheese dressing for dipping, if desired.
