I've never made them with Ritz crackers instead of pretzels before. By the way, Ritz now makes a "mini" Ritz-and-peanut-butter-filling-cracker-snack.

I usually just dip the pretzels into 1 Cup each melted semi-sweet morsels and milk chocolate morsels (microwaved on high with 1 Tb. shortening) and stirred 'til smooth.

But I think I'll to the Ritz mini pb sandwich crackers instead. Mmm!
