SANTA'S MAGIC COCOA

Better than cookies & milk! Here's a gift idea that your kids—and even Santa—will warm up to fast!

What you'll need:
1 bag MILKY WAY® Brand Miniatures
1 STARBURST® Brand Candy Cane
1 tablespoon unsweetened cocoa
1 tablespoon brown sugar
1 small plastic bag
1 piece of thin ribbon
1 recipe card
1 large microwave-safe mug
What to do:

Combine the cocoa and the brown sugar in a small plastic bag, and tie the plastic bag with a piece of ribbon. Place the plastic bag inside a microwave-safe mug. Place the MILKY WAY® Brand Miniatures and the STARBURST® Brand Candy Cane in the mug.

Have your child write the following instructions on a recipe card and include it in the mug:

Heat a cup of milk in your microwave oven for one minute. Stir in the hot chocolate mix. Chop a MILKY WAY® Brand Miniature into small pieces and stir it into the hot chocolate. Heat the mixture for another minute, until it is hot and bubbly. Use the STARBURST® Brand Candy Cane to stir your hot chocolate. Enjoy!
