It is a layered mousse whipped with cream, and a fluffy textured and crispy oat crumble. The best time to eat is in summer.
Ingredients
- FOR THE CRUMBLE
- 4 graham crackers
- 3/4 c. rolled oats
- 1/3 c. packed light brown sugar
- 3 tbsp. all-purpose flour
- 6 tbsp. cold butter, cubed
- FOR THE MOUSSE
- 1 1/2 c. heavy cream
- 1/4 c. powdered sugar
- 1 c. sweetened condensed milk
- 1/3 c. freshly squeezed key lime juice
- 1 tsp. pure vanilla extract
- Green food coloring (optional)
- Key lime wedges, for garnish
Instructions
Steps:
1. Preheat 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. Make 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. In 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. Assemble: 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. Place 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. Keep refrigerated until ready to serve.
