Use a cookie scoop to transfer the dough onto a parchment-lined baking sheet. Bake in a preheated 425 °F oven for 10 minutes then lower the heat to 350 ° and bake for another 15 minutes.
Remove from oven and use the tip of a sharp knife to poke a hole in the side of the cream puffs to release the steam and open up enough space to spoon in the filling.
Once the cream puffs are completely cooled then spoon the pudding into the cream puffs. Sprinkle the cream puffs with powdered sugar right before serving.
