### Instructions:

**Step 1: Cook the Pasta**
Bring a large pot of salted water to a boil. Cook macaroni until just al dente (about 1 minute less than package directions). Drain and set aside.

**Step 2: Make the Roux**
In a large saucepan, melt butter over medium heat. Whisk in flour and cook for 2-3 minutes, stirring constantly, until it turns light golden and bubbly.

**Step 3: Add Milk and Cream**
Slowly whisk in milk and cream, a little at a time, ensuring no lumps. Continue whisking until sauce thickens, about 5-7 minutes.

**Step 4: Season and Add Cheese**
Remove sauce from heat. Stir in mustard, garlic powder, salt, and pepper. Gradually add shredded cheeses, stirring until melted and smooth.

**Step 5: Combine Pasta and Cheese Sauce**
Add cooked pasta to cheese sauce, stirring gently to coat every piece.

**Step 6: Prepare for Baking**
Preheat oven to 350°F (175°C). Transfer mac and cheese to a greased baking dish.

**Step 7: Add Breadcrumb Topping (Optional)**
Toss breadcrumbs with olive oil or melted butter. Sprinkle evenly over the top.

**Step 8: Bake**
Bake for 25-30 minutes or until top is golden brown and bubbly.
