1-First Step: Gather and prep your ingredients Set out the 5.1 oz vanilla instant pudding mix, 3 cups cold milk, bananas, whipped topping, and vanilla wafer cookies before you begin. Slice the bananas thinly so they layer neatly and do not overpower the dessert. If you want to garnish the top, slice a few extra bananas and set aside a small handful of crushed cookies. Using cold milk is important here. Instant pudding thickens best when the milk is very cold, so keep it in the refrigerator until you are ready to mix. This small step helps the filling set faster and smoother.

2-Second Step: Make the pudding filling In a large bowl, whisk the vanilla instant pudding mix with the 3 cups of cold milk. Keep whisking until the mixture starts to thicken. This usually takes just a couple of minutes, and the pudding should look smooth with no dry powder left behind. Once the pudding has thickened, fold in half of the 8 oz whipped topping. Folding means gently mixing it in with a spatula instead of stirring hard. That keeps the filling light and fluffy. The texture should look creamy and soft, which helps it spread easily between the cookie and banana layers.

3-Third Step: Build the first layer in the baking dish Grab a 9×13 baking dish and start with a layer of vanilla wafer cookies across the bottom. Try to cover the surface evenly so each spoonful has a bit of cookie in it. After the cookies, add a layer of sliced bananas. You do not need to make it perfect, but it helps to keep the banana slices in a fairly even layer. Now spoon half of the pudding mixture over the bananas and spread it gently so the layer reaches the corners. The goal is to keep the layers neat without pressing down too much. The cookies and bananas should stay in place while the pudding covers them.

4-Fourth Step: Repeat the layers Add another layer of vanilla wafer cookies, followed by another layer of banana slices. Then spoon the remaining pudding mixture on top and spread it evenly. This second round gives the dessert height and makes every bite feel balanced. At this stage, the dessert should already look rich and inviting. You will see the familiar banana pudding layers that make this recipe such a crowd favorite. If you like layered sweets, this is the same kind of easy, satisfying idea that makes no bake desserts so practical for home cooks.

5-Fifth Step: Add the topping Spread the remaining whipped topping over the pudding layer. You can smooth it flat with a spoon or create gentle swirls for a prettier look. If you want a more classic finish, keep the top clean and simple. If you want a more festive look, add a few banana slices and a sprinkle of crushed vanilla wafers on top. The topping helps seal in the moisture while the dessert chills. It also gives the finished dish a soft, fluffy look that contrasts nicely with the cookie layers underneath.

6-Final Step: Chill and serve Cover the dish and refrigerate it for at least 2 hours. If you have the time, chilling overnight works even better because the cookies soften and the flavors blend together more fully. This waiting time is what turns the dessert from a layered pudding dish into a true banana pudding recipe with that classic soft texture. Before serving, garnish with fresh banana slices and crushed cookies if you like. Serve cold, using a spoon to scoop through all the layers. The dessert serves 12, which makes it a great choice for family meals and gatherings.
