Follow the instructions on the white cake mix package to prepare the batter.
Pour the batter evenly into a 9×13-inch baking pan and bake as directed on the package.
Step 2: Cool the Cake
Allow the baked cake to cool at room temperature for about 30 minutes.
Step 3: Create Perforations
Once the cake is cooled, use the end of a wooden spoon or a meat fork to make evenly spaced perforations across the surface.
Ensure the perforations penetrate halfway through the depth of the cake.
Step 4: Prepare and Apply the Gelatin
In a separate bowl, combine the raspberry-flavored gelatin with 2 cups of hot water. Stir until completely dissolved.
Pour the gelatin mixture evenly over the cake, ensuring it seeps into the perforations.
Step 5: Apply Raspberry Preserves
Warm the raspberry preserves in the microwave for about 30 seconds, or until spreadable.
Spread the warmed preserves evenly over the gelatin-layered cake.
Step 6: Add Whipped Topping
