bags white chocolate chips (I like Ghiradelli)
bags bittersweet (or semisweet) chocolate chips (I like Ghiradelli)
cups Rice Krispies
Place 3/4ths of the white chocolate chips in a glass or metal bowl. Place over a pan of simmering water and stir until melted. Remove from heat and stir in the remaining white chocolate chips until melted. (If the chocolate is too thick, stir in some Crisco...about 1 TBSP). Stir in the Rice Krispies. Spread onto a cookie sheet, lined with parchment paper. (An offset spatula works great.) Melt the bittersweet chocolate using the same method. (You shouldn't need the Crisco here.) Using an offset spatula, gently spread over the white chocolate. Sprinkle on the conversation hearts and sprinkles. Let set up until hardened. Break into pieces.
