Preheat oven to 375°.

Roll sausage into 18 equal balls. Place on a foil-lined baking sheet.

Bake sausage at 375° until cooked through, about 12 minutes.

While sausage is cooking, whisk together bisquick, milk, and egg.

Coat a mini muffin tin with nonstick spray. Fill each cup about halfway, then press a cooked sausage ball in the center. The batter should rise not quite to the top of the tin.

Bake at 375° for 12 minutes, until edges are browned.

Serve with warm maple syrup for dipping.
