Preheat Oven: Set oven to 350°F (175°C).
Arrange Cones: Place flat-bottom cones upright in a muffin tin to keep them steady.
Mix Batter: Prepare cupcake batter following the box or recipe instructions.
Fill Cones: Spoon batter into each cone, filling about two-thirds full. Do not overfill.
Bake: Place muffin tin in oven and bake for 18–22 minutes, or until a toothpick comes out clean.
Cool: Let cones cool completely on a wire rack before frosting.
Frost: Use a piping bag (or zip bag with corner cut) to swirl frosting on top, making it look like soft-serve ice cream.
Decorate: Add sprinkles, mini chocolate chips, or drizzle chocolate sauce for extra flair.
Serve & Enjoy: Best served the same day while cones are crisp and fresh.
