Ingredients
Scale
- 4 graham crackers
- 3/4 cup rolled oats
- 1/3 cup packed light brown sugar
- 3 tablespoons all-purpose flour
- 6 tablespoons cold butter, cubed
- 1 1/2 cups heavy cream
- 1/4 cup powdered sugar
- 1 cup sweetened condensed milk
- 1/3 cup freshly squeezed key lime juice
- 1 teaspoon pure vanilla extract
- Green food coloring (optional)

Instructions
- Preheat oven to 350°F. Pulse graham crackers in food processor to fine crumbs.
- In a bowl, combine graham cracker crumbs, rolled oats, brown sugar, and flour.
- Add cold cubed butter and mix with fingers until pea-sized clumps form.
- Spread mixture evenly on baking sheet and bake 20 minutes, stirring halfway, until golden and crisp. Cool.
- In a large bowl, beat heavy cream with powdered sugar until stiff peaks form. Reserve 1 cup whipped cream for topping.
- In separate bowl, mix sweetened condensed milk, key lime juice, vanilla extract, and optional green food coloring.
- Fold condensed milk mixture gently into remaining whipped cream until combined.
- In four glasses, layer about 1/4 cup graham cracker crumble, then 2 spoonfuls mousse; repeat layers until glasses are nearly full.
- Pipe reserved whipped cream on top of mousse in each glass.
- Sprinkle remaining graham cracker crumble on top and garnish with key lime wedge.
- Refrigerate mousse until chilled and set before serving.
Notes
