Step 1: Prepare and bake the red velvet cake according to package directions in a 9×13 inch pan. Let cool completely.
Step 2: Crumble the cooled cake into fine crumbs in a large bowl using your hands or a fork.
Step 3: Mix cream cheese frosting into the cake crumbs until fully combined and the mixture holds together when pressed.
Step 4: Roll the mixture into 1-inch balls and place on a parchment-lined baking sheet. Chill in refrigerator for 30 minutes.
Step 5: Melt white chocolate chips with vegetable oil in a microwave-safe bowl in 30-second intervals, stirring until smooth.
Step 6: Insert a lollipop stick into each chilled cake ball, then dip into melted chocolate, tapping gently to remove excess.
Step 7: Sprinkle with red velvet crumbs if desired, then stand upright in a styrofoam block or cake pop holder to set.
