Start by mixing all of the dry ingredients together.
Then add the egg, butter, and milk and whisk it all in.
Combine it all well. Pour it into the silicone mold, you don't need to spray it because the butter is in the ingredients.
Then pour 1 1/2 cups of water into your Instant Pot.
Set the trivet in the Instant Pot.
Wrap the silicone mold up in paper towels, then wrap it in foil, and then place the silicone cup mold on top of the trivet.
Set the time for 5 minutes on high pressure. When the time is up, wait 2 minutes and then do a quick release.
