Plop the batter into twelve muffin cups and using wet fingers smooth the tops a bit. I like to add 2 or 3 extra blueberries to the muffin tops.
Once cool enough to handle, scoop the flesh out of the squash and transfer it to a food processor. Process until smooth.
Place a pot of water over high heat for the pasta. Once at a boil, add some salt and the pasta, and cook to al dente according to package directions. Drain the cooked pasta and return it to the pot it was cooked in.
While the pasta water is heating up, place a small skillet over medium-high heat with the butter. Once melted, add the flour and cook about a minute. Whisk in the milk and cook until the liquids come up to a bubble and the sauce thickens, 2-3 minutes. Add the squash puree, nutmeg, cinnamon and sage, and season with salt and pepper to taste.
Add the sauce to the pot with the reserved cooked pasta and toss to coat. Turn everything out into a baking dish and sprinkle the top with cheeses. Transfer to the oven and bake until the cheese is brown and bubbly, 10-15 minutes.
