• Add the white chocolate chips to a medium mixing bowl
• Melt the butter in a small bowl in the microwave (go slow or it explodes)
• Warm the cream in a small sauce pan until you see wisps of steam
• Pour the cream over the chips and let them sit for a minute
• Whisk until smooth
• Add butter and whisk until incorporated
• Refrigerate until very cold
• Whisk again to lighten the ganache when ready to use
