In the bowl of a stand mixer with the whisk attachment, pour in the cream. Start to whip, gradually going from 1-8 with your speed. You may need to put on the splash shield.
Whip past soft and hard peaks, until the butter fat separates from the buttermilk. This took me about 12-15 minutes. (This is when the splash shield will come in handy!)
Once the butter fat has separated, drain the buttermilk into a bowl or jelly jar, through a fine sieve. Reserve the buttermilk for later. It's great to use in cakes, waffles, or even pancakes!
Remove the remaining butter fat to a medium sized bowl and press with a spatula to remove any remaining buttermilk. Run (yes, for real) the butter fats under gently running, but very cold, water. Continue to fold and press until the water runs clear.
The butter will be dense, slightly yellow, and very rich.
Place the butter back into the mixer bowl with a whisk attachment. Add the vanilla extract, honey, and a pinch of salt. Whip until well mixed and aerated, about 3 minutes. Transfer to a ramekin or bowl, and cover with plastic wrap. Refrigerate until firm.
Use within 1 week.
