Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Cream cheese gives the mousse its rich and creamy base. Softened cream cheese blends smoothly and creates a cheesecake-like texture.

Sweetened condensed milk adds sweetness and a silky consistency while enhancing the citrus flavor beautifully.

Key lime juice is the star ingredient that provides the bright and refreshing tangy flavor. Fresh key lime juice gives the best taste, though bottled key lime juice can work in a pinch.

Lime zest intensifies the citrus aroma and adds freshness throughout the mousse.

Heavy whipping cream creates the light and fluffy texture that makes this dessert feel airy and luxurious.

Powdered sugar lightly sweetens the whipped cream while helping maintain a smooth consistency.

Vanilla extract balances the tartness of the lime and adds warmth to the flavor profile.

Graham cracker crumbs create the classic key lime pie flavor. Sprinkling them between layers or on top adds delicious texture.

Unsalted butter combines with the graham cracker crumbs to create a buttery crumble topping.

Whipped cream adds a beautiful finishing touch while making the dessert look bakery-worthy.

Directions

Begin by preparing the graham cracker crumble. In a bowl, mix the graham cracker crumbs with melted butter until evenly coated. Set aside.

In a large mixing bowl, beat the softened cream cheese until smooth and creamy. Slowly add the sweetened condensed milk while continuing to mix.

Pour in the key lime juice, lime zest, and vanilla extract. Continue mixing until the filling becomes silky and fully combined.

In a separate bowl, whip the heavy cream with powdered sugar until soft peaks form. Gently fold the whipped cream into the lime mixture using a spatula. This step creates the mousse’s airy texture.

Spoon a layer of graham cracker crumble into serving glasses or dessert cups.

Add a generous layer of key lime mousse over the crumble. Repeat the layers if desired until the glasses are filled.

Top each mousse cup with whipped cream, extra lime zest, or additional graham cracker crumbs for garnish.

Cover the dessert cups and refrigerate for at least 2 hours before serving. Chilling helps the mousse set properly and enhances the refreshing citrus flavor.

Serve cold and enjoy the creamy, tangy, and refreshing dessert.
