Step 1: Make the Dough
In a large mixing bowl, whisk together the Bisquick mix, granulated sugar, and nutmeg.
In a separate bowl, whisk the milk, egg, and vanilla extract until smooth.
Pour the wet ingredients into the dry and stir just until a soft dough forms.
Dust your work surface with a little Bisquick and turn out the dough. Gently knead a few times to bring it together.

Step 2: Roll & Cut the Donuts
Roll the dough out to about ½-inch thickness.
Use a donut cutter to cut out donut shapes. Gather scraps and repeat until all dough is used.
If you don’t have a donut cutter, use a 3-inch round cutter or glass and a 1-inch cutter to remove the centers.

Step 3: Heat the Oil
Pour vegetable oil into a heavy-bottomed pot or deep skillet to about 2 inches deep.
Heat over medium heat until it reaches 350°F (use a thermometer for best results).
Prepare a cooling rack with paper towels underneath for draining.

Step 4: Fry the Donuts
Carefully add 2–3 donuts at a time to the hot oil.
Fry for 1–2 minutes per side or until golden brown and puffed.
Use a slotted spoon or tongs to remove and place on the cooling rack. Repeat with all donuts and holes.

Step 5: Add Your Toppings
For cinnamon sugar: Mix granulated sugar and cinnamon in a bowl. Brush warm donuts with melted butter, then roll in cinnamon sugar.
For glazed donuts: Whisk powdered sugar, milk, and vanilla until smooth. Dip slightly cooled donuts into the glaze and let set on a rack.
You can also try chocolate glaze or powdered sugar for variety!
