Citrus Whipped Cream
1 cup whipping cream
2 tbsp icing sugar
1 tbsp fresh lemon zest, or more!
Whip the cream in a stand mixer or use a hand held mixer. Start on lower speed and increase till medium high. As soon as it is fully foamy, add the sugar and zest and continue on high speed till firm and spoonable. This can be made ahead of time and stored in the fridge till needed.
