Melt the 7 tbsp. of butter, white chocolate, and milk chocolate. You can use a double boiler method, or put it in the microwave for 30 second intervals mixing in between until it all mixes smoothly.
Add salt, vanilla, and sugar. Whisk until smooth.
Add the eggs and whisk until combined.
Add flour and food coloring and whisk again until combined.
Grease the ramekins and then dust with cocoa powder.
Spoon mix into the ramekin. Divide evenly into each one.
Place the Instant Pot trivet into the bottom of Instant Pot bowl. Add the cup of water to the IP bowl.
Place the ramekins on the trivet. It's ok to stack the ramekins like a pyramid if they don't all fit on one level.
Close IP and set on high pressure for 9 minutes.
Once the cooking is done wait 3 minutes and manually release the pressure. You can also quick-release the pressure as soon as it is done cooking if you want a less dense cake.
Carefully remove from IP with tongs and let cool a bit. Serve warm and enjoy!
