Preheat your oven to 325°F (163°C) and prepare your silicone molds by spraying them with nonstick spray.

In a large mixing bowl, combine the cake mix, water, oil, and eggs. Mix until smooth and well combined.

Fill each cavity of the prepared molds halfway with the cake batter.

Bake in the preheated oven for 10 to 15 minutes until lightly golden and a toothpick inserted comes out clean.

Remove from the oven and cool completely on a wire rack, waiting at least 15-20 minutes before removing from molds.

Melt white chocolate chips in a microwave-safe bowl, heating in short bursts and stirring frequently until smooth.

Sprinkle Funfetti Halloween Sprinkles into the bottom of each mold and layer with melted chocolate to create a base.

Press each cooled cake into the chocolate layer, ensuring they sit evenly atop the sprinkles.

Cover the molds with plastic wrap and freeze for at least 2 hours.

Once frozen, invert the molds to release the mini cakes and enjoy your spooky treats!
