Start by cracking two eggs into a glass so you can check their freshness. Occasionally, eggs may be rotten, and you don't want to discover this after they're in your batter. Beat the eggs with a whisk.
It's crucial to pour the sugar and whisk the eggs simultaneously, and do it quickly. If sugar comes into direct contact with an egg yolk, it can accidentally cook the yolk, leading to lumps in your batter. Next, add milk and oil and mix.
Sift the flour and baking powder and incorporate them into the batter. Ensure everything is well mixed with the help of a whisk. If you spot any flour lumps. You can blend the batter until it's smooth.
Place your non-stick pan on low heat and add a few drops of oil. Spread the oil with a paper towel. Once the pan is slightly warm (not too hot), add your pancake batter, cover it with a lid, and cook for about a minute on low heat.
Now, add Nutella on top to your heart's content. Then, add more batter on top, but only cover the Nutella. Keep the lid on and check it periodically. You'll know it's time to flip it when you see bubbles forming, and it's starting to cook, but not fully. Avoid flipping it after it's fully cooked to prevent dryness.
The first pancake is usually not the prettiest. As you continue making them. They'll become more appealing. Also, there's no need to add oil to each pancake; just use the oil from the initial paper towel spread. Enjoy your Nutella-filled pancakes!
