Dice 16 oz. strawberries (about 1 package) into tiny pieces. Set aside.
Process Nilla Wafers in a food processor until you have 2 cups of crumbles. You can also put them in a bag and roll them with a rolling pin until they’re finely crumbled. Melt 4 tbsp. butter and mix into crumbles thoroughly.
Whip 1 cup heavy whipping cream with a hand-mixer in a large mixing bowl until small peaks form. Fold in, and mix 8 oz. whipped cream cheese with 1 tbsp. vanilla extract, a 14 oz. can condensed milk (only use ⅔ if you’d like it less sweet) and ½ cup lemon juice.
Spoon about 2-3 tsp. of the crumbles into your jars or cups – enough to make your first layer, and gently pat-down.
Fill a pastry bag (or just spoon) your mouse on top of the first crumble layer. Add another crumble layer, then spoon strawberries on top. Add the mousse again, then crumbles then strawberries and you’re done!
Place your sweet little mousses in the fridge for at least 4 hours so they set nicely.
