Prep the pan: Line a rimmed baking sheet with parchment paper. For thicker bark, use a quarter sheet.
For thinner bark, use a half sheet.
Soften the cream cheese: Let it sit at room temperature 20–30 minutes. This ensures a smooth, lump-free base.
Beat the base: In a bowl, beat cream cheese with powdered sugar, vanilla, and a pinch of salt until silky and smooth, about 1–2 minutes.
Lighten it up: Add Greek yogurt or sour cream and mix until fully combined. Pour in heavy cream and beat until the mixture is thick, fluffy, and spreadable.
It should hold soft peaks.
Spread: Dollop the mixture onto the parchment and spread into an even layer about 1/4 to 1/3 inch thick. Thicker layers yield a creamier bite; thinner layers freeze snappier.
Add toppings: Sprinkle crushed graham crackers over the surface. Add berries and any extras like mini chips or nuts.
Press gently so they adhere.
Optional swirl: Warm a spoonful of jam in the microwave until loose, then drizzle and swirl lightly with a toothpick.
Freeze: Place the sheet flat in the freezer for 2–3 hours, or until very firm.
Break and serve: Lift the parchment onto a cutting board. Use your hands to break into bark pieces, or use a sharp knife for cleaner shards.
Enjoy: Serve immediately, or return pieces to the freezer until you’re ready to eat.
