Rainbow Truffles

Ingredients:

1 pkg white cake mix, plus ingredients on back of box

1 small box sugar free/fat free vanilla instant pudding mix
1/3 can vanilla frosting
1 pkg white chocolate (or white almond bark)
Rainbow sprinkles
Red, golden yellow, lemon yellow, kelly green, royal blue and violet Wilton gel food coloring

Directions:

1. Preheat your oven to 350 degrees F. Line a muffin tin with 12 paper liners. First, prepare your cake mix according to package directions, stirring dry pudding mix into the batter to combine. Divide the batter evenly among six small bowls. Tint each bowl a different color of the rainbow to the intensity of your choice. I made my colors bright, but pastels would be cute, too!
2. Divide the colored batter into the muffin cups–2 muffin cups per one color–and bake about 13-15 minutes or when a toothpick inserted in the center comes out with light crumbs. Allow to cool completely.

3. Once cooled, crumble the cake by color into six separate bowls. Add about one Tablespoon or so of vanilla frosting to each bowl and mix with a spoon until combined.

4. To make the balls, take a small pinch of red crumbs, followed by orange, yellow, green, blue and purple. Once each color is in the palm of your hand, gently roll them into a tight ball. Place on a foil-lined baking sheet and repeat until all the crumbs are gone. Allow to harden several hours in the freezer.

5. Once chilled, melt the white chocolate. Once melted and smooth, dip each truffle one at a time into the melted chocolate with a toothpick, turning it gently to coat. Allow excess to drip off, then carefully release the coated cake ball back onto the baking sheet. Immediately sprinkle with rainbow sprinkles and repeat until finished. Allow chocolate to harden, then store airtight up to 2 days.
