Ingredients
- Lemon jello: provides the signature tart and sweet base try to choose a high-quality brand for the best lemon flavor
- Heavy whipping cream: brings a rich creamy texture to the mousse layer look for fresh cream with a good fat content for stable whipped peaks
- Powdered sugar: gives just enough sweetness to balance the tartness of the lemon pick finely milled sugar for a smooth result
- Water: is needed to dissolve the jello and create those perfect layers filtered water keeps flavors clean
I like to sometimes fold in a few fresh raspberries or chopped strawberries to add texture and color. Choose fruit that is ripe and firm so it holds up in the jello.
Step-by-Step Instructions
- Prepare the Lemon Jello:
- Dissolve the lemon jello in boiling water as directed on the package and stir until completely clear. Divide the mixture evenly among your individual glasses.
- Angle the Glasses for Layers:
- To create dramatic diagonal layers place each glass tilted in a muffin pan using a marshmallow or small support to hold them at an angle. Pour in the jello mixture and chill until fully set this usually takes about two hours. The angle gives the dessert an eye-catching look.
- Start the Lemon Mousse Layer:
- In a separate bowl dissolve more lemon jello in boiling water and let cool to room temperature. Do not allow it to set. This is important for a smooth mousse that blends easily.
- Whip the Cream:
- Pour heavy whipping cream into a chilled bowl. Using a hand mixer whip until soft peaks form. Add powdered sugar and continue to beat until stiff glossy peaks appear.
- Mix the Lemon Mousse:
- Slowly drizzle the cooled dissolved jello into the whipped cream while mixing on low speed. Beat just until combined and thick. Overmixing can deflate the mixture so stop as soon as it looks light and fluffy.
- Spoon Mousse Over Jello:
- Gently dollop or pipe the mousse over the firmly set jello base. Level out the tops for a neat finish.
- Chill and Garnish:
- Return the cups to the refrigerator and chill at least one more hour before serving. Add a swirl of whipped cream and a lemon slice right before serving for extra flair.

My favorite part is swirling on a generous dollop of mousse and letting my girls take charge of decorations. One birthday my youngest insisted on rainbow sprinkles on top and now it is our family tradition for these cups.
Storage Tips
Cover each jello cup with plastic wrap before refrigerating to keep them moist and fresh. If you plan to serve topped with whipped cream hold off until the last minute. These cups hold their shape beautifully for several days making them a perfect do-ahead party dessert.
Ingredient Substitutions
Feel free to swap lemon jello for any other flavor you love. Raspberry or orange bring a different color and taste. For the mousse use plant-based cream for a dairy free version and skip powdered sugar for a keto treat by using your favorite low carb sweetener.
Serving Suggestions
Dress up your jello cups for a special occasion by adding a fresh berry or little mint sprig on top. For summer barbecues serve them straight from the fridge in clear cups for a burst of sunshine after a meal.
