01 - Preheat the oven to 350°F. Line a baking sheet with parchment paper and prepare a taco rack or position oven rack bars for shaping.
02 - Using a 3-inch round cutter, cut circles from each flour tortilla. Brush both sides of each round generously with melted butter, then dip into the cinnamon-sugar mixture until evenly coated. Drape the coated tortillas over the oven rack bars or a taco mold to form the taco shell shape. Bake for 8 to 10 minutes until golden and crisp. Allow shells to cool completely on the rack.
03 - Place the freeze-dried strawberries and golden sandwich cookies into a food processor. Pulse until the mixture reaches a crumbly texture with some small chunks remaining, being careful not to over-process into a fine powder. Transfer to a bowl and set aside.
04 - In a mixing bowl, beat the softened cream cheese, powdered sugar, and vanilla extract with an electric mixer until completely smooth and creamy. In a separate chilled bowl, whip the cold heavy cream to stiff peaks. Gently fold the whipped cream into the cream cheese mixture in two additions until fully incorporated and no streaks remain.
05 - Combine the diced fresh strawberries, granulated sugar, and lemon juice in a small bowl. Toss gently and let the mixture macerate at room temperature for 10 minutes until the strawberries release their juices and a light syrup forms.
06 - Transfer the cheesecake filling to a piping bag or use a spoon to fill each cooled taco shell, dividing the filling evenly among all 8 shells. Sprinkle the strawberry crunch topping generously over the exposed filling. Drizzle with the prepared strawberry sauce if desired.
07 - Serve the cheesecake tacos immediately for a soft, creamy texture, or refrigerate for 1 hour to allow the filling to set firmly before serving.
