In a tall measuring cup or mason jar pour 250g Milk and add 80g Einkorn Flour. Use your immersion blender to combine these two ingredients.
Next in a large saucepan, pour in 1250g Milk. Turn your heat to medium and whisk in your milk/flour mixture slowly.
Whisking your milk mixture occasionally, use your emptied container and put 100g Sugar, 1 pinch Salt, and 6 Egg Yolks into the jar and mix.
Once the milk/flour mixture is steaming, we will take out about 1 cup to temper the egg.
To temper your egg mixture, slowly pour the hot liquid in, while whisking the egg mixture.
Now slowly pour, while whisking continuously, the egg mixture back into the milk/flour mixture in the saucepan.
Keep whisking for about 20 minutes until the pudding begins to bubble and becomes thick.
Once it has reached a thick consistency, turn off your heat and stir in 1 Tbsp Vanilla Extractand 56g Butter.
Set aside and allow it to cool completely. I recommend placing it in the fridge after it has let off steam for at least 10 minutes.
While the pudding is cooling, prepare the Double Batch Homemade Whipped Cream.
Once the pudding is completely cooled, mix 3 cups into the pudding.
Next, layer cookies and banana slices on the bottom of your dish. Alternating 1/3 of the pudding mixture over cookie/banana layers until you have used it all.
Top with the second batch of homemade whipped cream evenly over the top.
Optional: sprinkle crushed up cookies over the top and place a few whole cookies around.
