Preheat the oven to 425F. Line a standard muffin pan with paper baking cups.
In a medium bowl, whisk together the dry ingredients. Set aside.
In the bowl of a stand mixer fitted with a paddle attachment, add the eggs and sugar. Beat together until the mixture is light and fluffy, about 3 minutes.
With the mixer running on low, slowly drizzle in the oil. (Do this slowly so you keep the air you mixed into the eggs/sugar.) Add the lemon juice and vanilla extract and mix.
With the mixer running on low, add ⅓ of the flour mixture followed by ½ of the yogurt. Mix until combined then add another ⅓ of the flour mixture.
Add the rest of the yogurt and mix until combined. Then add the rest of the flour and mix until incorporated. Scrape down the sides and bottom of the mixer and mix for another 15-20 seconds until the batter is totally smooth.
Stir in the chocolate chips with a rubber spatula. Using a kitchen scoop or large spoon, portion the batter evenly into the prepared muffin tin. Sprinkle the raw sugar evenly over the top of the muffins.
Bake the muffins for 10 minutes, then turn down the heat to 375F. Continue to bake for another 10-15 minutes, until the muffins are lightly browned on top and a toothpick inserted into the center comes out clean.
Let the muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely. Enjoy!
