Step 1: Melt the Chocolate - Gather a microwave-safe bowl, add semi-sweet chocolate chips and vegetable oil. Heat using 30-second intervals, stirring after each interval until fully melted and smooth, about 1-2 minutes total.

Step 2: Coat the Crackers - In a large mixing bowl, pour in the Ritz Bits peanut butter crackers. Drizzle the melted chocolate mixture over the crackers and toss gently until fully coated.

Step 3: Prepare the Coating - Combine the powdered sugar and hot chocolate mix in a zip-top bag. Add the chocolate-coated Ritz Bits, seal tightly, and shake until fully covered.

Step 4: Set the Snack - Line a baking sheet with wax paper, pour the coated Ritz Bits onto it, and break apart any clumps. Allow them to cool for 10-15 minutes until the chocolate hardens.

Step 5: Store or Serve - Once set, store in an airtight container for up to one week if not serving immediately.
