Jumbo Muffin Keys to Success

Find the Ripest Bananas You can Find

Ripe bananas have much more flavor. Adjust the flour if you have to. Because bananas differ in their moistness as they ripen, you may have to add a couple of tablespoons of flour.

We also like to add extra banana flavor to add an extra punch. The banana flavor really makes these muffins pop, and they’re absolutely scrumptious.

Adjust the Cooking Time and Temperature

Start out with a hot oven. Preheat the oven to 400 degrees and then reduce the temperature as directed. The initial hot oven creates a burst of steam that helps lift the muffins and create a crispier top.

Check the cooking time. This is the same recipe as for standard-sized muffins except that the baking times are different. Because you turn the temperature down for the jumbo muffins, times are only an estimate and reflect the time required in our oven. Other ovens may retain heat as ours does.
