Mix together the flour, sugar, baking powder and salt in a bowl.
Add in egg, milk, butter and vanilla extract.
Mix the ingredient together until just combined (don’t worry if there are a few lumps).
Spray or lightly oil two silicon molds and divide the mixture equally into the molds until they are about two-thirds of the way full.
Add a few berries into the mixture, if you are using them.
Cover the silicone tray with the tray cover and then cover it with foil around the edges so no condensation can seep into the breakfast bites.
Add 1 1/2 cups of water to the Instant Pot and stack the silicon molds on the trivet and add to the Instant Pot.
Cover Instant Pot with lid, seal, and set on Pressure Cook or Manual on High for 8 mins and cook until done.
Allow for a Natural Pressure Release for 2-3 mins then perform a quick pressure release to release the rest of the pressure.
Remove the trays, discard foil and open.
Tip the trays over and gently tap the bottom of the mold to remove the bites.
Serve warm with maple syrup and extra berries.
