Ingredients
8 oz cream cheese, softened to room temperature
1/3 cup granulated sugar (optional but recommended for sweetness and structure)
2 cups frozen whipped topping, thawed (such as Cool Whip)
2 cups fresh strawberries, hulled and finely diced
1/2 cup chopped pecans, plus 2 tablespoons extra for sprinkling on top
Directions
Prepare the pan: Lightly grease a 9×9-inch square glass baking dish or mist it with nonstick spray. This helps the frozen fluff release more easily when you slice it. Set aside on your counter.
Soften the cream cheese: Place the softened cream cheese in a medium mixing bowl. If it still feels a bit firm, let it sit at room temperature for another 10–15 minutes. Soft cream cheese will blend more smoothly and prevent lumps in the finished fluff.
Sweeten the cream cheese: Add the granulated sugar to the cream cheese. Using a hand mixer (or a sturdy whisk and some elbow grease), beat until the mixture is smooth, creamy, and the sugar is mostly dissolved, 1–2 minutes. Scrape down the sides of the bowl as needed.
Fold in the whipped topping: Add the thawed whipped topping to the cream cheese mixture. Using a spatula, gently fold until the mixture is evenly combined and pale pink once the berries go in—avoid overmixing, which can deflate the whipped topping and make the texture less fluffy.
Add strawberries and pecans: Gently fold in the finely diced strawberries and 1/2 cup chopped pecans until they are evenly distributed throughout the creamy mixture. You should see red berry pieces and nutty bits dotting the pale pink base.
Transfer to the dish: Scrape the strawberry fluff mixture into the prepared 9×9-inch glass dish. Use your spatula to spread it into an even layer, smoothing the top so it has a level, creamy surface.
Top with extra pecans: Sprinkle the remaining 2 tablespoons of chopped pecans evenly over the surface. This gives the top a little texture and makes the finished dessert look inviting, like a classic potluck “salad.”
Freeze until firm: Place the dish on a flat shelf in your freezer and freeze, uncovered, for at least 4 hours, or until the fluff is firm all the way through. For the cleanest slices, freeze it overnight.
Slice and serve: When you’re ready to serve, remove the dish from the freezer and let it sit at room temperature for about 10 minutes to soften just slightly. Use a sharp knife to cut the fluff into squares and a small spatula to lift them out. Serve cold, and watch the pan get practically licked clean.
