Heat 1 tablespoon of the butter and 1/4 cup of the honey in a large nonstick skillet over medium heat. Stir to combine. Add 6 of the muffin halves to the skillet, cut-side down. Cook, without turning, until golden and crisp, 3 to 5 minutes. Transfer to a plate. Repeat with the remaining butter, honey, and muffins. Let cool.

In a large bowl, beat the cream and sugar with an electric mixer until soft peaks form. Place 4 muffin halves on individual plates, cut-side up, and top with some of the whipped cream and peaches. Add a second muffin half to each stack and top with the remaining whipped cream and peaches. Sandwich with the remaining muffin halves.
