1. Preheat your oven to 375°F (190°C) and lightly grease a 12-cup muffin tin with non-stick spray or butter. This step is key to getting your muffins to pop out easily later on.
2. Cook the elbow macaroni according to package instructions until al dente. Drain well and set aside. I like to toss the pasta with a little olive oil to keep it from sticking while I prepare everything else.
3. In a small saucepan, melt the butter over medium heat. Once melted, whisk in the flour and cook for about 1 minute to form a roux. This little step gives your muffins that creamy texture without lumps.
4. Slowly add the milk to the roux, whisking constantly until the mixture thickens and starts to bubble gently—about 3-4 minutes. Remove from heat and stir in the Dijon mustard, garlic powder, smoked paprika, salt, and pepper.
5. In a large mixing bowl, beat the eggs lightly. Add the thickened milk mixture and stir until combined.
6. Add the cooked macaroni, chopped bacon, jalapeños, and both cheeses to the bowl. Gently fold everything together, making sure the cheese is evenly distributed throughout the macaroni.
7. Carefully spoon the mixture into the prepared muffin tin, filling each cup about three-quarters full. Don’t be shy with the filling; these muffins should be packed with cheesy goodness.
8. Bake in the preheated oven for 18-22 minutes, or until the tops are golden brown and a toothpick inserted in the center comes out clean. The aroma at this point will have your family gathering in the kitchen in no time.
9. Allow the muffins to cool in the tin for 5 minutes before gently removing. Serve warm for the best gooey, melty experience.

From personal experience, I’ve found that letting the muffins rest a few minutes really helps them set up so they don’t crumble when you take that first bite. It’s a simple step that makes a big difference in texture.
