How to Make Key Lime Dessert Squares

  1. Preheat oven to 350°F (175°C).
  2. **Prepare the Pecan Crust:** Spread 1 cup of pecans evenly in a shallow baking pan.
  3. Bake for 5-7 minutes, or until lightly browned. Remove from oven and let cool slightly.
  4. In a large bowl, combine the cooled pecans, 1 box (15.25 oz) Duncan Hines Deluxe White Cake Mix, and 1/2 cup (1 stick) melted unsalted butter.
  5. Stir until crumbly and well combined. Press the mixture firmly into the bottom of an ungreased 13x9 inch baking pan.
  6. **Make the Key Lime Filling:** In a medium bowl, whisk together 2 large egg yolks, 1 (14 oz) can reduced-fat sweetened condensed milk, 1/2 cup Key lime juice (about 4-5 limes), and a few drops of yellow food coloring (optional) until smooth.
  7. Pour the key lime filling evenly over the pecan crust.
  8. Bake at 350°F (175°C) for 15-20 minutes, or until the filling is set. The edges will be slightly set, and the center will still jiggle slightly.
  9. Let cool completely on a wire rack for at least 15 minutes.
  10. Refrigerate for at least 2 hours, or until completely chilled.
  11. **Serve:** Cut into squares, top with dollops of reduced-fat whipped topping and lime slices (optional), and enjoy!
