Preheat and Prep: Preheat your oven to 350°F (175°C). Line a 6-cup muffin tin with paper liners or spray with non-stick cooking spray.
Mix Wet Ingredients: In a medium bowl, whisk together the ricotta cheese, eggs, sugar, and honey until smooth and creamy, about 2 minutes. Stir in the vanilla extract and lemon zest.
Combine Dry Ingredients: In a separate bowl, whisk together the 1/2 cup flour, baking powder, and salt.
Fold Together: Gently fold the dry ingredients into the ricotta mixture until just combined. Don't overmix—a few lumps are fine.
Prepare Blueberries: In a small bowl, toss the blueberries with 1 tablespoon of flour to coat. This prevents them from sinking to the bottom.
Add Berries: Fold most of the blueberries into the batter, reserving a few for topping.
Fill Muffin Cups: Divide the batter evenly among the 6 muffin cups. They should be about 3/4 full. Press the reserved blueberries onto the top of each cake.
Bake: Bake for 22-25 minutes, until the tops are golden brown and a toothpick inserted in the center comes out clean.
Cool: Let the cakes cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
