Preheat the oven to 350 degrees F. Line a sheet pan with parchment paper.
Add the butter to a small pot and place over medium heat. Melt the butter and cook until the milk solids start to turn golden brown and release a toasty and nutty aroma, 3 to 5 minutes. Set aside.
In a large bowl, combine the animal crackers, rainbow crackers, pretzel crackers, graham crackers and Cheddar crackers. Add the brown butter and toss to coat all the crackers. Transfer to the prepared sheet pan.
Bake until the crackers absorb the brown butter mixture, 4 to 5 minutes. You don’t want the crackers to brown. Let cool to room temperature. Add the diced apricots and mix to combine.
