All ingredients ready? Let's begin!
In a large mixing bowl add the all-purpose flour, sugar and yeast and combine.
Add one egg and mix together.
Add warm milk, the warm milk activates the yeast better. Mix everything together with a whisk or electric mixer.
Cover with a plastic wrap and set aside for 1 hour. This will let the batter rise.
In an hour the batter should have doubled in size. If it hasn’t, cover the batter again and let it rest some more. Keep it in a warm place.
Heat the Poffertjes pan and spray with oil or dab each cup with butter.
Spoon a little of the batter into each cavity. Let it cook for a minute or two.
Once the top starts bubbling or forming little holes, flip it over with the skewer or chopsticks gently.
Let it cook on other side for about 1-2 minutes. Repeat for all the Poffertjes.
Remove from the pan, add a small slab of butter on top and sprinkle with powdered sugar.
