Mix first 5 ingredients in a large bowl. Preheat a non-stick pan over medium heat.
Pour the mixture into the warm pan and let cook for about 30 seconds, then sprinkle blueberries into the batter.
Cover pan with a lid and let cook about 2 minutes. When the cake is fluffy, flip it over, cover and let cook for another 2 minutes. Check now and then to make sure it’s not burning. The pancake is done when it rises back after being pressed with the spatula.
Spread a layer of peanut butter on top and serve.
