01 - Preheat the oven to 350°F. Line a baking sheet with parchment paper if desired.
02 - Using a 3-inch round cutter, cut circles from each flour tortilla. Brush both sides of each circle generously with melted butter, then dip into the cinnamon-sugar mixture, coating evenly. Drape the coated tortilla rounds over the bars of an oven rack or a taco-shaped baking mold. 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 several times until the mixture reaches a crumbly texture with small visible pieces, stopping before it becomes 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, folding 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 sit at room temperature for 10 minutes until the strawberries release their juices and form a light syrup.
06 - Transfer the cheesecake filling to a piping bag or use a spoon to fill each cooled taco shell generously. Sprinkle the strawberry crunch topping over the filling, pressing gently so the crumbs adhere. Drizzle with the optional strawberry sauce if desired.
07 - Serve the tacos immediately for a soft, creamy texture, or refrigerate for 1 hour to allow the filling to firm up for a more structured bite.
