Instructions
Heat the oven and prep the pan: Arrange a rack in the middle of a regular or toaster oven and heat to 350°F. Place the butter in a mini square or round metal pie pan and place the pan on top of the toaster oven or inside the regular oven as it heats to melt. Pour the melted butter into a small heatproof bowl. Use a brush to coat the pan with the residual butter left in the pan; set aside.
