Place all ingredients in a high powdered blender, like the Vitamix, and blend on high until mixture becomes a batter.
Stir in 1/4 cup chocolate chips. Place batter in a 7 in spring form pan, and sprinkle the top with remaining 2 tbsp chocolate chips.
Cover pan with a paper towel then place foil over top.
Add 1.5 cups of water to your Instant Pot. Set your pan on top of the trivot and place inside of the pressure cooker.
Place lid on the pot and make sure the vent valve is in the SEALING position. Then select the MANUAL/PRESSURE COOK function, HIGH PRESSURE. Use the +/- arrows to select 60 minutes.
When the time is up let the pot naturally vent the pressure for 10 minutes. When the display panel reads 10, open the pressure valve.
Remove cake and allow it to cool for a couple minutes
