2/3cuppineapple juice(the juice from the can of pineapple rings)
In a large bowl, mix the cake mix, oil, pineapple juice and eggs on med/high for 2 minutes.
Spray 6 (6 oz) ramekins with cooking spray. Add 1 tbsp of brown sugar to the bottom of each ramekin.
Divide the melted butter between all 6 of the sugared ramekins (just pour it into each one-no need to stir or mix it)
Over the brown sugar, place a pineapple ring and add a cherry to the center of the ring.
Pour the cake batter over the pineapples, dividing evenly between the 6 ramekins. Just fill them 3/4 of the way-I stop just below the line at the lip of each one. (There will be cake batter left over)
Add 1 cup of water to the inner pot and place the trivet inside. Stack three ramekins on the trivet and then stack the other three on top by offsetting them just a bit. Close and lock the lid, turning the steam release valve to closed.
Press Steam and then Start/Stop. (Defaults to 10 minutes on High.) When the cooking time is up, do a quick pressure release and carefully pull out the ramekins. Some of the cakes may have risen above the edge of the ramekins, but that's fine.
Cool on a cooling rack for 5-10 minutes before turning out onto a plate.
Use the extra cake mix to make another 1-2 individual cakes OR pour it into an egg bites mold and make cake bites! Cook the bites on steam for 5 minutes with 5 minutes NPR and then pop them out while still warm. Top with frosting for a sweet bite!
