Combine oat milk, vanilla extract, eggs, and melted butter in a mixing bowl. Note: if you use cold ingredients, your butter might harden and make the mixture clumpy. This won't hurt the batter and will incorporate while mixing (in this scenario, you might see small pockets of butter pop up while cooking).

In a separate bowl, mix flour, baking powder, and salt.

Combine dry ingredients with the wet ingredients and mix until everything is combined and smooth.

Heat a pan or griddle on medium to medium-low heat. Add butter or oil to the pan to ensure the pancakes don't stick.

Using a ¼ cup measuring cup, scoop the batter onto the prepared pan or griddle. Flip after 20-30 seconds or when you begin to see bubbles forming throughout the uncooked side of the pancake. It will only need 10-20 seconds on the other side.

Plate with butter and maple syrup. Enjoy!
