1/3 cup oilOlive oil, canola, grapeseed, and avocado oil are great options.
3egg whitesfrom whole eggs, not the carton of egg whites
6ozbox strawberry jelloI use large box of sugar-free jello for a lighter option
1cupsboiling water
1/2cupcold water
1cupcold milkYou can use low-fat milk to lighten it up
3.4ozpuddingcheesecake, vanilla, and white chocolate are great options. I used sugar-free to reduce calories and sugar
1tspvanilla extract
confectioners sugar to tasteI leave it out completely
8ozfrozen non-dairy whipped topping thawed, you can also use a cup of heavy whipping cream
Instructions
Combine the oil, egg whites, cake mix, and amount of water as directed on the box and mix until combined.
Pour into a 9x13 baking pan sprayed with baking cooking spray and bake according to package directions (since this can vary slightly per mix)
Allow the cake to cool to room temperature.
While cake is cooling, mix the jello with the boiling water until dissolved and add the 1/2 cup of cold water.
Prick holes in the cake with a large skewer or fork every two inches being careful not to go all the way to the bottom. Pour jello mixture over the cake.
Refrigerate uncovered overnight, or at least two hours.
In the bowl of an electric mixer, use a whisk attachment to mix the last 5 ingredients until smooth and fluffy. Spread on the chilled cake. Refrigerate until served. Store in the refrigerator and garnish with fresh strawberries, if desired.
Notes
Wait until the jello powder is fully dissolved in the boiling water before adding the cool water.
You can also add a tablespoon of the jello powder to your frosting for a subtle fruity flavor and a hint of color.
Sneak a layer of fresh strawberries or strawberry pie filling on top of the cake before layering on the frosting.
