Print Recipe


  • 1 Jumbo muffin pan


  • 3 cups all-purpose flour
  • 4 tsp baking powder
  • ½ tsp salt regular salt, not coarse
  • 2 large eggs room temperature
  • 1 cup cane sugar
  • ½ cup lemon-infused olive oil
  • Zest of 1 large lemon
  • ¼ cup ricotta cheese whole milk OR part-skim: See NOTES
  • ¾ cup buttermilk
  • 1 tsp vanilla extract
  • 1 cup fresh blueberries
  • Cooking spray
  • ¼ cup coarse sugar such as turbinado


  • Preheat oven to 425°F.
  • In a large bowl, whisk together the flour, baking powder and salt until blended (about 30 seconds of gently blending with a whisk or fork).
    3 cups all-purpose flour, 4 tsp baking powder, ½ tsp salt
  • In a separate medium-sized bowl, use a fork or wooden spoon to mix the eggs with the sugar. Stir until blended. Add the oil, lemon zest, ricotta cheese, buttermilk, and vanilla, and mix until incorporated.
    2 large eggs, 1 cup cane sugar, ½ cup lemon-infused olive oil, Zest of 1 large lemon, ¼ cup ricotta cheese, ¾ cup buttermilk, 1 tsp vanilla extract
  • Using your hands, or a large wooden spoon, form a well in the center of the flour mixture.
  • Add the egg/oil mixture and the blueberries into the well area you created in the flour mixture.
    1 cup fresh blueberries
  • Using the wooden spoon, fold the dry ingredients into the wet, slowly, until all pockets of flour have been incorporated. About 1 to 2 minutes. The batter will be very thick and resemble moist cookie dough.
  • Spray a large muffin pan with cooking/baking spray, including the top of the pan.
    Cooking spray
  • Use a large spoon or ice cream scooper to fill each muffin holder nearly to the brim.
  • Top each muffin with a healthy pinch of sugar crystals.
    ¼ cup coarse sugar
  • Bake for 6 minutes and then reduce oven temperature to 375°F and continue baking for 22 - 25 minutes, or until tops are lightly brown, and an inserted toothpick comes out clean.
  • Carefully remove muffins from the tin as soon as possible. If left in the pans, the bottoms will become soggy.
  • Let cool for at least 10 minutes on a rack.

Lemon olive oil can be found in many well-stocked supermarkets. Our favorite lemon oil is from Rancho Azule y Oro. They are an amazing family-run olive oil producer from California. We HIGHLY recommend them. 
For the ricotta cheese, go with whole milk ricotta to achieve muffins that are slightly more dense, but not heavy. For lighter, fluffier muffins, use part-skim ricotta. 
The muffins will stay fresh in an air-tight container with a lid for up to 5 to 6 days. They are best freshly baked, but still delicious throughout the week. 
The muffins can be frozen (fully wrapped) for up to 2 months.
