Preheat oven to 350°F (176°C) and prepare an 8×8-inch dish or pie pan with parchment paper or grease.
Make the crust: Blend oats, almonds, salt, and sugar into a fine meal. Mix with melted coconut oil until dough-like.
Press & Bake: Press into the pan, bake for 15 minutes, then increase temperature to 375°F (190°C) and bake for 5-10 minutes until golden. Let cool.
Prepare pudding: In a saucepan, whisk cornstarch, sugar, salt, and almond milk over medium heat until thick. Remove from heat, stir in vanilla, and cool for 10 minutes.
Chill pudding: Transfer to a bowl, cover with plastic wrap touching the surface, and refrigerate for 2-3 hours.
Make coconut whip: Chill a mixing bowl in the freezer. Scoop the solid part of coconut cream, whip for 1 minute, then mix in vanilla & powdered sugar for 2-3 minutes. Chill for 30 minutes.
Combine: Once pudding is set, fold it gently into the coconut whip.
Assemble: Layer sliced bananas on the crust, then spread the pudding-coconut mixture on top.
Chill: Cover and refrigerate for at least 4 hours, preferably overnight.
Serve & Enjoy! Garnish with more whipped cream & bananas.
