A molten lava cake you can make in the microwave, that is packed with protein and can be made in 5 mins. Recipe very slightly adapted from Cleobuttera
Every microwave is different, start by cooking it for 1 min 20 seconds, test the top (shouldn't have much water) and add more time in 10-15 second increments until done.
If you don't want to eat it in the mug, spray the mug with no-stick spray, and mix everything in a bowl instead of in the mug. Then after cooking, tip over onto a plate.
Garnish with whipped cream and berries!
