In a large bowl, whisk together the eggs and the butter. Then, add in the vanilla and heavy cream, whisk until combined.
In a separate bowl, add in the flour, baking soda, baking powder, sugar and salt.
Turn on the pan or skillet to medium-low heat. You don't want it super hot, the batter is thick and needs time to cook.
Combine the dry and wet ingredients until smooth and free of lumps. Add a little butter to the skillet then add about a ladle full of pancake batter to the skillet. Spread the batter out the best you can then allow the pancake to cook.
After a few minutes flip the pancake. Should be golden, allow the other side to cook. If inexperienced, use a tooth pick to test the pancake doneness once you flip it. If the toothpick comes out clean they are ready.
When the pancake is ready, remove from the heat and place on a plate then repeat the steps until all the batter is gone.
