Place all ingredients except blueberries/chocolate chips in a large bowl. Using an immersion blender, blend until smooth.

Fold in chocolate chips or blueberries.

In a small skillet over medium heat, heat a bit of oil or butter.

Use a scooper to scoop batter into skillet and cook for two minutes, until pancake holds its shape and can easily be flipped.

Flip and cook for another minute.

Repeat until batter is finished, adding oil or butter as necessary.

Serve immediately with maple syrup (optional).
