In a small bowl, stir gelatin with cold water and let bloom for 5 minutes.
In a stand mixer fitted with the whisk attachment, whip cream until soft peaks form (about 3–4 minutes). Transfer to a bowl and refrigerate.
In the same stand mixer bowl (switch to paddle attachment), beat cream cheese until smooth, about 2–3 minutes.
Scrape down the sides, add granulated sugar, yogurt, and lemon juice. Beat until fully combined and creamy.
Microwave the bloomed gelatin for 10–15 seconds until melted. Let cool briefly. Remove whipped cream from fridge and stir approximately ¼ cup into the melted gelatin to help incorporate it smoothly.
Add this mixture to the cream cheese base and fold gently to combine. Continue to fold in the remaining whipped cream until fully blended.
Stir in ½ tsp Hedessent Cappuccino Flavour Drops and 20 drops Hedessent Vanilla Cookie Flavour Drops until well combined.
Pour into the prepared crust and smooth the top. Cover and refrigerate for at least 4 hours or overnight.
