Ingredients
For the Cake
- 1 box white or vanilla cake mix (plus ingredients listed on the box)
- 1 (3 oz) package raspberry gelatin mix
- 1 cup boiling water
- 1 cup cold water
For the Topping
- 1 (8 oz) container Cool Whip, thawed
- 1 (8 oz) can crushed pineapple, drained
- 1 cup fresh raspberries (plus extra for garnish)
- 1/2 cup shredded coconut (optional)
Instructions
Prepare the Cake
- Preheat your oven according to the instructions on the cake mix package. Grease a 9×13-inch baking dish to prevent sticking.
- Mix the cake batter as directed on the package and pour it into the prepared baking dish.
- Bake according to the package instructions, then let the cake cool completely before adding the gelatin mixture.
Add the Raspberry Gelatin
- In a medium bowl, dissolve the raspberry gelatin mix by stirring it into 1 cup of boiling water until completely dissolved.
- Add 1 cup of cold water to the dissolved gelatin and stir to combine.
- Using a fork or skewer, poke holes evenly across the surface of the cooled cake. Carefully pour the gelatin mixture over the cake, allowing it to soak into the holes. Refrigerate for at least 1 hour to set.
Prepare the Fluff Topping
- In a large mixing bowl, gently fold together the Cool Whip, drained crushed pineapple, fresh raspberries, and shredded coconut (if using).
- Stir until all ingredients are well combined, forming a light, creamy topping.
Assemble and Serve
- Once the cake has chilled, spread the prepared fluff topping evenly over the entire surface of the cake.
- Garnish with additional fresh raspberries if desired, adding a pop of color and freshness.
- For best results, chill the assembled cake for an additional hour before serving to allow the flavors to meld.
Serving Suggestions
This Raspberry Fluff Cake is delightful served chilled, especially on warm days. It makes an excellent addition to a dessert table, picnic, or summer potluck. For an elegant touch, try garnishing each slice with a fresh raspberry or two and a small sprig of mint. Pair it with light beverages like iced tea or sparkling water with lemon for a refreshing finish.
Storage Tips
- Refrigeration: Cover any leftover cake with plastic wrap or foil and store in the refrigerator for up to 3 days. The Cool Whip topping may start to soften, so enjoy it fresh for the best texture.
- Freezing: This cake is not ideal for freezing as the gelatin and topping may lose texture when thawed.
Helpful Notes
- Cake Mix Variations: White or vanilla cake mix works well, but for a twist, you could try a lemon cake mix to complement the fruity topping.
- Fruit Substitutions: If raspberries aren’t available, strawberries or blackberries make excellent substitutes.
- Cool Whip Alternatives: You can use homemade whipped cream instead of Cool Whip if you prefer a fresher, creamier topping.
- Adding Texture: Try sprinkling a handful of chopped nuts, like pecans or almonds, on top for added crunch.
Chef Tips
- Chef Martha Stewart: For an extra fresh flavor, she suggests adding a splash of lemon juice to the gelatin mixture, which enhances the fruity notes.
- Chef Ina Garten: To elevate presentation, Ina recommends layering slices of fresh raspberry or strawberry along the cake’s edges before serving.
- Chef Mary Berry: Advises using a light hand when folding the fluff topping ingredients to avoid deflating the whipped topping for the fluffiest texture.
