A light, airy, and velvety no-bake dessert that transforms classic chocolate sandwich cookies into a polished, chilled treat perfect for summer cookouts or easy entertaining.
Twist open each Oreo cookie and gently scrape the white filling into a large mixing bowl, keeping the chocolate wafers intact.
Place the chocolate wafers into a zip-top bag, setting aside 4 halves for garnish. Use a rolling pin to crush the remaining wafers into fine, sandy crumbs.
Spoon 2 to 3 tablespoons of the cookie crumbs into the bottom of each serving glass to create a structured base.
Whip the Mousse
Add the heavy cream and vanilla extract to the bowl with the Oreo filling. For a flavor boost, add a pinch of sea salt and 1/2 teaspoon of espresso powder, then whip until the mixture holds stiff peaks.
Using a spatula, gently fold the remaining crushed cookies into the whipped cream using broad strokes to maintain the airy volume.
Fill the Cups
Divide the mousse evenly among the prepared glasses. You can use a piping bag for a neater, bakery-style finish.
Garnish and Chill
Top each cup with a dollop of Reddi-whip and the reserved cookie pieces.
Serve immediately for a crunchy texture, or refrigerate until serving for a firmer, more set mousse.
Notes
Pro Tip: Chill your bowl and whisk attachment in the freezer for 15 minutes before whipping to help the cream trap air more efficiently.Texture Secret: If the Oreo filling is very firm, microwave it for 10 seconds before adding the cream to ensure a silky smooth mousse without lumps.Storage: These cups keep well in the refrigerator for up to 3 days. Note that the cookie crumbs will soften over time, creating a cake-like texture.Substitution Tip: For a dairy-free version, use chilled full-fat coconut cream and ensure your sandwich cookies are vegan-friendly.Nutrition information is estimated based on common ingredients and serving sizes and may vary.
