Craving Banana Pudding

Hi everybody.  Hope all is well.

My daughter is almost three months pregnant, and she was craving banana pudding.  This is no big deal right? except my daughter has a casein protein intolerance, she allergic to proteins in cows milk. Now you see my dilemma.  She has been drinking almond milk, rice milk and soy milk since she was 9 years old, so I went to the trusty Internet to find which one of these dairy alternatives would make the best banana pudding.:

I found a great recipe at silk.com  Here's the recipe:

Ingredients
1/2 cup sugar
1/3 cup cornstarch
1/2 tsp salt
3 cups Silk almond milk
3 Tbsp butter
1 tsp vanilla extract
Vanilla wafers
4 ripe bananas

Pudding
1. Whisk together sugar, cornstarch and salt in a saucepan.
2. Slowly whisk in Silk, making sure there are no lumps. Bring mixture to a boil over medium heat, whisking constantly.
3. Lower heat and simmer, whisking occasionally until mixture thickens, about 3-4 minutes.
4. Remove from the heat and whisk in margarine and vanilla. Cool.

To assemble
5. Spread a layer of vanilla wafers in a 9x9 square baking dish, top with half of the banana slices and half of the pudding.
6. Continue with another layer of vanilla wafers followed by remaining bananas and ending with remaining pudding, spreading to cover all banana slices.
7. Cover with plastic wrap and chill overnight
