Raspberry Jello Cake Ingredients
For the Cake
Large Eggs Essential for a light and airy texture; using room temperature eggs yields better results.
Granulated Sugar Sweetens the sponge cake; substitute with a sugar alternative if desired.
Vanilla Extract Adds a delightful depth of flavor; opt for pure vanilla to enhance taste.
All-Purpose Flour Provides structure to the cake; feel free to use gluten-free flour if needed.
Warm Water Helps dissolve sugar for better mixing; cold water can be used, ensuring even incorporation.
For the Mousse
Raspberry Jello The star of the mousse, providing sweetness and flavor; other flavored jellos can be swapped in for variation.
Cool Whip Works as a stabilizer for the mousse; homemade whipped cream is a great substitute for a richer taste.
For the Syrup
Granulated Sugar (for syrup) Adds moisture and sweetness; you can adjust or omit depending on your taste preference.
Lemon Juice Lends acidity to the syrup, enhancing the overall flavor; vinegar can work in a pinch.
For the Topping
Raspberry Jello (for topping) Creates a beautiful glaze over the mousse; any fruit-flavored jello can also be used.
Fresh Raspberries Adds a burst of fresh flavor and color; feel free to substitute with blueberries or strawberries if you prefer!
How to Make Raspberry Jello Cake
Prepare the Jello Mousse: Begin by dissolving raspberry jello in 1 cup of boiling water, stirring until fully dissolved. Then, add 1 cup of cold water and let it sit until it becomes syrupy and slightly thickened.
Make the Cake: Preheat your oven to 350°F (175°C). In a bowl, beat together 4 large eggs and 1 cup of granulated sugar until thick and pale. Gently fold in 1 teaspoon of vanilla extract and 1 cup of sifted all-purpose flour. Bake in a parchment-lined dish for 18-20 minutes, or until golden brown and a toothpick comes out clean.
Cool the Cake: Carefully invert the baked cake onto a wire rack to cool completely. Once cooled, brush the top of the cake with a syrup made from 1/4 cup of granulated sugar dissolved in 1/4 cup of warm water mixed with a splash of lemon juice.
Finish Mousse: In a separate bowl, beat the cooled jello mixture with 8 oz of Cool Whip until fluffy. Spread this luscious raspberry mousse over the cooled cake, then top with fresh raspberries for a pop of color.
Create Jello Topping: To finish, dissolve another package of raspberry jello in 1 cup of boiling water, let it cool slightly, and gently pour it over the mousse layer using the back of a spoon to prevent mixing. Refrigerate the cake until the jello is fully set.
Optional: Add a sprinkle of fresh mint for a refreshing garnish!
