1 stick unsalted Butter, room-temperature, softened
2-3T REAL Maple Syrup, room temperature
zest of 1 Orange
Using paddle attachment, whip the butter until fluffy, scraping down sides of bowl as needed. With mixer on low, gradually drizzle in the syrup. Add zest, then increase speed to medium and whip for another minute or so.
You can also just whip it by hand, which sounds both kinky and exhausting.
