Pour the semi-sweet and dark chocolate chips into a medium microwave-safe bowl, (I like glass bowls) and heat the chocolate chips in 30-second intervals until the chocolate is melted, stirring after each heating. (I know this is tedious, but it sure beats burning your chocolate that ends up in the trash.)
Once melted, allow the chocolate to cool for about 2 or 3 minutes. Add the chopped nuts, cranberries and noodles to the melted chocolate.
Using a silicone spatula, gently fold these ingredients together to thoroughly combine.
Lay out about a two-foot long sheet of wax paper on your counter or tabletop to place the haystacks, giving them time to cool and set up.
Using a spoon (I used a regular soup spoon), scoop out about a golfball-size amount of the haystack mixture and using your finger, slide it off the spoon and onto the wax paper. You may need to use your fingers or your spoon to gather the haystacks together if they’re falling apart. You want to have a mound shape.
While the chocolate is still “wet,” sprinkle a pinch of white chocolate chips on top of each stack.
Scoop the rest of the mixture onto the wax paper, following steps 5 and 6, spacing about an inch apart. (You just want a little space so they’re not touching and attaching to each other when they cool.) Continue sprinkling white chocolate chips as you lay each of them out.
Allow the haystacks to cool at room temperature for about 2 hours, or you can pop them in the fridge for about 20 minutes.
Once the chocolate is set, you can serve them or place in an air-tight container. They are fine at room temperature or kept refrigerated.
