Pour heavy cream into the bowl of a stand mixer {or into a large bowl if using a hand mixer} beat until whipped and the peaks hold their shape. Scoop into a small bowl and set aside.
Add powdered sugar and, starting on low, mix until completely incorporated and smooth. Add vanilla extract and Meyer lemon zest and juice. Beat until fully incorporated.
Spoon the mixture into a serving dish and refrigerate for an hour or so to let the flavors marry. Before serving, remove from refrigerator and let it sit for 15-20 minutes so it softens a bit.
