Cook the macaroni according to the package instructions until al dente. Drain and set aside.
Preheat an oven to 400°F (200°C). Grease a baking sheet with cooking spray and set it aside.
In a large saucepan, melt the butter over medium heat. Add the flour and whisk continuously for about 2 minutes until the mixture is smooth and bubbly.
Gradually pour in the milk while whisking constantly. Continue to cook and stir until the mixture thickens, usually for about 5 minutes.
Reduce the heat to low and add the shredded cheddar cheese to the sauce. Stir until the cheese has melted and the sauce is smooth. Season with salt, black pepper, garlic powder, and paprika. Mix well.
Remove the saucepan from the heat and add the cooked macaroni to the cheese sauce. Stir until the macaroni is evenly coated.
Allow the mixture to cool slightly. Then, add the beaten eggs to the macaroni mixture, stirring until well combined.
Spread the breadcrumbs on a plate or shallow dish. Take a spoonful of the macaroni mixture and shape it into a wedge using your hands. Roll the wedge in the breadcrumbs, making sure it's evenly coated. Place it on the prepared baking sheet. Repeat this process until all the macaroni mixture is used.
Lightly spray the tops of the wedges with cooking spray to help them crisp up in the oven.
Bake the mac and cheese wedges in the preheated oven for about 15 minutes, or until they are golden brown and crispy.
Remove the baking sheet from the oven and let the wedges cool for a few minutes before serving.
Serve your mac and cheese wedges warm as an appetizer or side dish.
