Preheat oven to 350 degrees F. Line a 15x10x1-inch rimmed pan with foil. Lightly spray the foil with nonstick baking spray.
Place the crackers in a single layer on the prepared pan.
In a medium saucepan, add the butter, sugar and salt. Place over medium heat and stir until butter is melted.
Let the mixture come up to a boil and let boil until light brown in color, about 7 to 9 minutes while stirring frequently.
Remove from the heat and add the vanilla. Stir until blended. It will bubble slightly when the vanilla is added.
Immediately pour the mixture evenly over crackers and spread with an angled spatula to cover the crackers.
Place the pan into the preheated oven and bake for 13 to 15 minutes until bubbly.
Place the almond bar in a microwave-safe large bowl and microwave in 30-second increments. Stir after each increment and repeat until the almond bark is completely melted and smooth.
Repeat with the candy melts, add the red and green candy melts to separate microwave-safe bowls and microwave in 30-second increments, stirring after each increment until completely melted.
Pour the almond bark over the cracker mixture and evenly spread out with the angled spatula.
Drizzle the red and green chocolate on top of the white.
Swirl the colors together with a butter knife or skewer. Don't overmix the colors otherwise you'll have brown swirls instead of Christmas swirls.
Sprinkle with festive sprinkles while the chocolate is still wet.
Let the ritz candy cool completely, about 2 hours or until chocolate is set before breaking the candy into pieces.
Store in an airtight container in a cool place.
The Wilton candy melts will become incredibly thick if they're old. You can add ½ teaspoon to 1 teaspoon of refined coconut oil or vegetable oil to thin out the candy melts. You can skip the candy melts and melt an additional 1 cup of white almond bark. Divide the almond bark into two bowls and add red candy color to one bowl until the desired color is reached and green candy color to the second bowl until the desired color is reached.
