Put the butter in a small bowl and melt it by microwave or stove. Allow it to cool off.
Combine the oats and the water/milk together in a medium bowl. Set it aside for 10 minutes. During this time, gather all other ingredients and equipment.
Add the butter, sugar, vanilla, and eggs to your oat bowl. Stir until everything is well combined.
Mix all remaining ingredients (flour, baking powder, salt, and cinnamon/nutmeg) in with the wet ingredients. If it helps, try mixing the dry ingredients in a separate bowl or add them in one at a time. Mix everything together until you have a well-combined batter.
Heat a skillet over a stove at medium heat. Lubricate the skillet with a bit of butter and drop some batter in to form a pancake that is 4 inches in diameter.
Once the bottom of your pancake appears cooked and golden-brown, flip the pancake over with a spatula. The time it takes to cook varies depending on the temperature. Be sure to set your stove to medium-low heat over time to prevent burning the pancake.
Once your flipped-over pancake appears golden-brown on the bottom, remove it and serve it on dish.
Repeat steps 5-7 until the pancake batter is finished. Serve with some whipped cream or maple syrup if you prefer.
