Nothing says summer quite like a tart key lime pie. This mousse is every bit as refreshing, with a fluffy texture and a crispy oat crumble we could eat on its own. Key limes are more tart than traditional limes; they’re worth finding for this mousse. The sweet and tart combo hit all of the right notes for a quintessential summer dessert.

Directions

1. Step 1Preheat oven to 350°. In a food processor, pulse graham crackers into fine crumbs. In a medium bowl, combine crushed graham crackers, oats, brown sugar, and flour. Add butter and use your hands to cut into mixture until pea-sized and mixture starts to hold together. Spread mixture into an even layer on a baking sheet. Bake until golden and crisp, about 20 minutes, stirring halfway through. Let cool.
2. Step 2Make mousse: In a large bowl, using a hand mixer (or in the bowl of a stand mixer fitted with the whisk attachment), beat cream and powdered sugar into stiff peaks. Remove about 1 cup of whipped cream to reserve for topping.
3. Step 3In a medium bowl, combine condensed milk, lime juice, vanilla, and a small drop of food coloring, if using. Add to bowl of whipped cream. Gently fold in until just combined.
4. Step 4Assemble: Add about ¼ cup of crumble to the bottom of 4 glasses. Top with two large spoonfuls of mousse, then repeat with another layer of crumble and mousse.
5. Step 5Place reserved whipped cream in a piping bag fitted with a large closed star tip, and pipe onto mousse. Top with any remaining crumble and a lime wedge in each glass.
6. Step 6Keep refrigerated until ready to serve.
