Coat a 9 x 13 in (3 L) baking pan with cooking spray or line with parchment paper. In a very large bowl, mix both types of cereal with cranberries, apricots, and coconut, if using.
Melt butter in a large wide saucepan
or Dutch oven set over medium-low heat. Add marshmallows and stir constantly, until melted and evenly combined, 6-10 minutes. (Prevent a sticky situation by lightly coating a wooden spoon with cooking spray or oil before stirring.)
Turn off heat, but leave saucepan on burner. Add cereal mixture and stir vigorously to combine. There's a lot to mix, so dig deep. Turn mixture into pan and, using a spatula sprayed with cooking oil, smooth the surface and press down to pack. Cool until firm, at least 2 hours. Remove from pan and cut into squares.
