First, measure out all your ingredients into small dishes. If you skip this skep, the candy will be begin to harden too quickly. 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 half way through, at 3 minutes. 

Line a Cookie sheet with Parchment Paper, and set aside.  

Remove from the Microwave, and add the Butter, and Microwave for 1 minute.

Remove bowl from the microwave, and 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 into pieces. 

Serve and Enjoy!
