Preheat your oven to 350°F (175°C) and prepare a 9-inch round cake pan by greasing it with butter or oil and dusting it with flour, or line it with parchment paper.
In a large mixing bowl, combine the plain Greek yogurt, granulated sugar, and vegetable oil, whisking until smooth.
Add the room temperature eggs, lemon zest, and freshly squeezed lemon juice to the yogurt mixture, whisking until creamy and fully combined.
In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt until evenly distributed.
Slowly add the dry mixture to the wet ingredients, folding them together gently until just combined.
Carefully fold in the fresh blueberries, ensuring they are evenly spread throughout the batter.
Transfer the batter into the prepared cake pan, spreading it evenly.
Bake in the preheated oven for 35 to 40 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
Dust the cooled cake with powdered sugar and garnish with additional fresh blueberries before serving.
Notes
Dust with powdered sugar and garnish with fresh blueberries for presentation.
