Combine the heavy cream and lavender in a small pot. Cover it with a lid, and bring the cream to a simmer. Don’t allow the cream to boil or simmer heavily. Once it reaches a simmer, take the pot off the heat, leave the lid on, and let the cream steep for 10 minutes.
Step 2
After steeping, strain the cream into a bowl. Set the infused heavy cream, covered, in the refrigerator for about 20 minutes, or until the cream is completely cold.
Step 3
Meanwhile, melt the butter in a microwave. Then, combine it with the remaining ingredients with a whisk or in a mixer with a whip attachment. Set this cream cheese mixture aside in a large bowl.
Step 4
Once the heavy cream is cold, place it in a clean mixing bowl with a whip attachment. Whip the heavy cream until you get medium-stiff peaks. Then, fold it into the cream cheese mixture.
Step 5
Serve the lavender vanilla mousse immediately in small serving cups. Enjoy!
