Sieve the dry ingredients into a medium sized mixing bowl.
Add the eggs and oil to a large measuring jug with a spout and whisk to combine.
Stir the milk and vanilla extract into the egg mixture.
Break up the drained ricotta with a fork (keep it chunky) and add to the egg mixture.
Pour the egg mixture into to the bowl of dry ingredients and gently mix to combine. The mixture will be thick and lumpy from to the ricotta, this will help make the pancakes thick and fluffy. To ensure light pancakes do not over mix.
Cover and set aside for 20 minutes. I know this is a drag if you're hungry but this step is important if you want the pancakes to rise well. Make yourself a cup of coffee. Clean out those forgotten tupperwares in the fridge. Have a shower. Time will go quickly.
Brush a skillet pan with oil and heat on a medium setting. Wait until the skillet is hot enough and sizzling.
Pour 1/4 cup or two large spoons of batter into the hot skillet. Dot several fresh blueberries into the batter.
Flip after several minutes - the edges will start to round out, the bottom will be golden-brown and several small bubbles will be present around the rim of the pancake. Try not to agitate after flipping.
Fry the other side for several minutes until golden brown and cooked through.
Serve with a knob of butter and a drizzle of maple syrup or honey.
