Small in size but mighty in flavor, these Chocolate Mousse Mini Oreo Cheesecakes pair a crunchy Oreo base with a silky cheesecake and a cloud-like chocolate mousse. They bake quickly, chill nicely, and make a striking dessert for parties or a weekend treat.
Why these mini Oreo cheesecakes steal the show
Mini cheesecakes are ideal when everyone wants their own portion. The combination of an Oreo cookie crust, a tangy cream cheese center, and a featherlight chocolate mousse creates layers of texture and flavor. Each bite mixes crunch, cream, and deep chocolate in a compact, elegant package.

Step-by-step: From crust to mousse
Follow these steps in order for best results. Keep an eye on textures more than exact times.
Make the Oreo crust
- Preheat oven to 350°F (175°C). Line a muffin pan with liners.
- Combine crushed Oreos with melted butter until the mix holds together.
- Press about 1 heaping tablespoon of crumbs into each liner. Bake 4–6 minutes. Let cool slightly.
Prepare the cheesecake filling
- Beat cream cheese until smooth. Add sugar and sour cream; mix on medium speed.
- Incorporate egg whites one at a time on low speed. Avoid overmixing.
- Mix in vanilla and flour until blended.
- Fill crusts nearly to the top with batter. Bake 20–25 minutes until centers are set.
- Cool on the counter, then refrigerate until fully chilled.
Create the chocolate mousse
- In a small saucepan, whisk egg yolks, powdered sugar, and 1/3 cup cream. Cook over low heat, whisking constantly, until the mixture thickens into a light custard.
- Remove from heat and stir in chopped chocolate until melted and smooth. Let cool to room temperature.
- Whip the remaining 1 1/3 cups cream to stiff peaks.
- Fold one-quarter of the whipped cream into the chocolate custard to lighten it. Gently fold in the rest until uniform.
- Stir in the crushed Oreos. If the mousse is too thick to pipe, add milk a tablespoon at a time until you reach the desired consistency.
Assemble, garnish, and store
- Pipe or spoon the chocolate mousse onto chilled cheesecakes.
- Top each mini cheesecake with a mini Oreo for an attractive finish.
- Keep finished cheesecakes refrigerated. Bring to room temperature briefly before serving for softer mousse.
- Store in an airtight container for up to 3 days.
Helpful tips and variations for better results
- Prevent curdling: whisk yolk mixture constantly while heating to avoid scrambling.
- Adjust sweetness: reduce powdered sugar in the mousse if you prefer less sweet desserts.
- No-bake option: skip baking the cheesecake layer and chill longer for a no-bake version.
- Chocolate swap: use dark chocolate for a more intense flavor.
- Make ahead: prepare mousse a day before and assemble on the serving day.
