These no-bake haystack cookies are crunchy clusters of chow mein noodles and marshmallow bits coated in melted white chocolate. Finish them with a chocolate drizzle and rainbow sprinkles, and they’re ready in 30 minutes!
Melt the white chocolate. Combine the white chocolate chips and vegetable oil in a microwave-safe bowl. Microwave in 30-second bursts, stirring well after each burst, until smooth. This can take up to 2 minutes, depending on your microwave.
Mix. Pour the melted chocolate into a large mixing bowl. Add the chow mein noodles and marshmallow bits and gently fold until evenly coated.
Scoop. Drop the mixture in roughly ½-cup mounds onto the prepared baking sheet, leaving a little space between them.
Decorate. Drizzle the haystacks with chocolate syrup and top with sprinkles.
Chill. Refrigerate for about 15 minutes, or until the chocolate coating is firm and the cookies lift easily from the parchment.
Notes
For dark chocolate haystacks, replace the white chocolate chips with 12 ounces of semisweet or dark chocolate chips and follow the same directions.
