First, measure out all your ingredients into small dishes you can pour into the Bowl of Candy because the Candy will begin to harden quickly, you'll need the ingredients ready to go to follow the recipe, and won't have time to get them together after you start.  DO NOT SKIP THIS STEP!

In a Microwave safe medium size bowl, add the Sugar, and Corn Syrup, and stir together.  Place in the Microwave for 6 minutes, on HIGH, stirring halfway through, at 3 minutes.  Line a Cookie sheet with Parchment Paper, and set it aside.   Remove from the Microwave, add the Butter, and Microwave for 1 minute. Remove Bowl, stir in Mini Pretzels, salt, and Vanilla, and Microwave for 15 seconds.

Remove Bowl, and stir in Baking Soda - the mixture will be light and foamy.  Quickly, pour the Brittle out onto the Parchment Paper lined Cookie sheet, and spread out into a thin layer with spoons, or forks - you'll need two utensils to spread the Brittle.  Let the Brittle cool for about 30 minutes, and make sure the Brittle is set, or hard to the touch.

Melt the White Chocolate in the Microwave, and stir until smooth.  Add a few drops of the Green Food Coloring Gel, and stir until blended.  Add more if needed to achieve the green color   Using a Fork, or small spoon, drizzle the melted Chocolate over the Brittle, leaving enough space for the Brittle to show through the chocolate.

Add the Red Grinch Hearts, pressing them slightly into the Green chocolate.  Allow about an hour for the Chocolate to completely harden, and all ingredients to cool completely.   When Brittle is cool, Break it into pieces.  Serve, and Enjoy!
