Creamy garlic butter pasta

Ingredients
10 oz dry pasta
3 Tbsp butter
4 large garlic cloves, minced
2 Tbsp flour
2/3 cup whole milk
salt & pepper

Instructions
Cook the pasta according to directions.
While the pasta is cooking, make the sauce.
Melt the butter in a saucepan over medium heat. Add the garlic and cook, stirring, for 1-2 minutes. It should be simmering.

After 1-2 minutes, transfer the butter/garlic to a blender, and blend until smooth. Return to the saucepan over medium heat and add the flour.
Whisk constantly, mixing the flour and butter together, for one minute. Slowly, whisking quickly, add the milk. Bring to a simmer and cook (stirring) until thickened.
When the pasta is done, mix in the sauce. Add salt and pepper as needed.
