Mix crust ingredients in a small bowl and press into a 13 x 9-inch pan (in EU & UK the best match is a 3L oblong pan). Place in the fridge while making the filling
Dissolve the gelatin mix in 1/2 cup boiling water; set aside to cool to room temp
Whip 1 1/2 cups of the cream, cream cheese and 1/3 cup confectioner's sugar until peaks form. Beat in the lukewarm gelatin mixture. Fold in the strawberries.
Spread filling on top of the crust.
In another bowl, beat the remaining 1 cup of heavy cream and 2 tbs confectioner's sugar until peaks form. Spread over the strawberry layer and chill at least 4 hours.
To prepare sauce, place strawberries in a food processor and process until it's smooth.
Notes
1 large tub (12 oz) may stand in for the whipped cream
