Whole Wheat Blender Pancakes

Place 1 cup milk and wheat berries in a blender; blend until smooth, 2 to 3 minutes.
Add remaining milk; blend for another 2 to 3 minutes. Add vegetable oil, egg, baking powder, agave, and salt; blend until incorporated, about 1 minute.

Spray a skillet or griddle with cooking spray and heat over medium-high heat. Drop batter by 1/3 cupfuls onto the griddle; dot with chocolate chips. Cook until bubbles form and the edges are dry, 3 to 4 minutes. Flip and cook until browned on the other side, 2 to 3 minutes. Repeat with remaining batter.
