This avocado lime mousse has become one of my favorite quick treats. It’s rich without feeling heavy, naturally creamy, and comes together in just a few minutes with simple ingredients.

If you’re following a low-carb or keto lifestyle—or simply looking for a flour-free dessert—you’ll definitely want to keep this recipe on repeat.

Ingredients

For the Mousse

• 2 ripe avocados
• 4 oz (115 g) full-fat cream cheese, softened
• 1 cup heavy whipping cream
• 2 tablespoons fresh lime juice
• 1 teaspoon lime zest
• 2–3 tablespoons powdered erythritol or your favorite low-carb sweetener
• 1 teaspoon vanilla extract
• Pinch of salt

Optional Toppings

• Whipped cream
• Extra lime zest
• Thin lime slices
• Crushed pork rinds (for a savory crunchy garnish) or crushed low-carb cookies if preferred
• Fresh mint leaves

Step-by-Step Method

Step 1: Prepare the Avocados

Cut the avocados in half, remove the pits, and scoop the flesh into a blender or food processor.

Step 2: Blend the Base

Add the cream cheese, lime juice, lime zest, sweetener, vanilla extract, and a pinch of salt. Blend until completely smooth with no lumps remaining.

Step 3: Whip the Cream

In a separate bowl, whip the heavy cream until soft peaks form. This helps create an incredibly light and fluffy texture.

Step 4: Fold Everything Together

Gently fold the whipped cream into the avocado mixture using a spatula. Take your time so the mousse stays airy.

Step 5: Assemble

Spoon or pipe the mousse into serving glasses or dessert cups. If you like the layered look, add a little garnish between layers.

Step 6: Chill

Refrigerate for at least 30–60 minutes before serving. The flavors become even better once chilled.

Step 7: Garnish

Top with whipped cream, fresh lime zest, lime slices, and your favorite crunchy topping just before serving.

• Fresh lime juice tastes much brighter than bottled juice.

• Taste before chilling and adjust the sweetness if needed.
• Chill well before serving for the best consistency.
