In a large bowl, combine dry ingredients. Add the milk and eggs and mix ingredients together until smooth.
Using nonstick cooking spray, grease the bottom and sides of your instant pot. Don't skimp on this step if you want the pancake to come out like an actual pancake ;)
Seal lid and set to low pressure. Cook for 45 minutes, or until the cake is springy to the touch and not at all wet.
Let the pancake set for 10 minutes or more. Use a spatula to remove pancake from pot. Serve with butter and maple syrup.
