Creating Blueberry Boyfriend Bait is simple if you follow these clear steps:

1. Preheat the Oven: Set your oven to 350°F (175°C) and grease a 9-inch square baking pan.
2. Prepare the Blueberries: Rinse the blueberries and set them aside to drain.
3. Mix Dry Ingredients: In a large bowl, whisk together the flour, granulated sugar, brown sugar, baking powder, baking soda, salt, and cinnamon until well combined.
4. Combine Wet Ingredients: In another bowl, mix melted butter, eggs, vanilla extract, and milk until combined.
5. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients. Stir gently until combined but be careful not to overmix.
6. Fold in Blueberries: Carefully fold in the blueberries, ensuring they are evenly distributed throughout the batter.
7. Pour into Pan: Pour the batter into the prepared baking pan, spreading it out evenly.
8. Bake: Place in the preheated oven and bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
9. Cool: Remove from the oven and let it cool in the pan for 10-15 minutes. Then transfer to a wire rack to cool completely.
10. Dust with Powdered Sugar: Before serving, you can dust the top with powdered sugar for added sweetness and decoration.
