First, prepare your cookie dough filling: In the bowl of a stand mixer, beat together the butter, peanut butter, brown sugar & white sugar with the paddle attachment until smooth and creamy, about 2 minutes. Add in the vanilla and milk and beat to combine. Lastly, add in the flour until a soft dough has formed.
Line two baking sheets with foil and spread the crackers in an even layer among both sheets. Using a teaspoon measuring spoon, spoon the cookie dough in a log-shape onto one of the crackers; gently top with another cracker, creating a sandwich. Repeat with the remaining cookie dough and crackers until all crackers are made into sandwiches.
Briefly allow the sandwiches to set in the freezer, for about 15 minutes. Meanwhile, melt the Chocolate CandiQuik according to package directions or until smooth and melted. Dip each sandwich into the Chocolate CandiQuik, allowing the excess to drip off of the fork. Return to the baking sheet and repeat with remaining sandwiches. Once the chocolate has set, melt the Vanilla CandiQuik. Place the Vanilla CQ in a baggy, seal out the air and snip off a corner. Pipe stitching onto each football, then allow the stitching to set.
Store leftovers airtight in the freezer and allow to come to room temperature before serving.
