In medium mixing bowl, whisk together flour, sugar, baking powder and salt.

In measuring cup, combine milk and oil. Pour mixture into dry ingredients and stir until just combined. (Note: A few lumps are fine.)

Add mix-ins, if using.

Let batter rest for 10 minutes.

Grease large skillet with non-stick spray and heat over medium-high heat. If using electric griddle, turn it to 350° F.

Pour ¼ cup portions of the batter onto hot skillet and cook for 2 to 3 minutes, until golden on bottom and bubbles appear on surface. Flip and cook 1-2 minutes.

Transfer to warm oven or plate. Repeat for remaining batter.

Serve warm with raspberries and maple syrup.
