Don’t let appearances deceive you when you’re making this recipe. The center cooks first in a microwave, while the top may appear slightly undercooked. Make sure to check with a tester so you don’t under- or overcook the banana bread. You may need to adjust the cooking time, depending on the wattage of your microwave.
