Preheat oven to 350°F (175°C). Grease an 8-inch round cake pan or line it with parchment paper.
In a large bowl, blend the cottage cheese, eggs, honey, and vanilla extract until smooth.
Stir in baking powder, salt, cinnamon, and gently fold in the fresh blueberries until evenly distributed.
Pour the batter into the prepared cake pan and bake for 25-30 minutes, or until a toothpick inserted comes out clean.
Allow the cake to cool in the pan for a few minutes before transferring to a wire rack to cool completely.
