Preheat oven to 425 °F (218 °C). Line a 12-cup muffin pan with paper liners.
In a medium bowl, whisk together all dry ingredients.
In another bowl or stand mixer, beat eggs and sugar until light and fluffy (about 5 minutes).
Slowly add oil while mixing on low. Stir in lemon juice.
Add ⅓ of the dry mixture, then half the yogurt. Repeat until combined.
Fold in your mix-ins gently with a spatula.
Divide batter evenly into muffin cups. Add raw sugar topping if desired.
Bake at 425 °F for 10 minutes, then reduce heat to 375 °F (190 °C) and bake 10–15 more minutes.
Cool in pan 5 minutes, then transfer to wire rack.
