  6. Step 6: Bake for 8 to 10 minutes, or until a toothpick inserted into the center of a muffin comes out clean.

Make-Ahead and Storage Tips

These muffins are fantastic for meal prepping or packing in advance. You can store them in an airtight container at room temperature for 2–3 days or pop them in the fridge for up to a week. For longer storage, freeze them in a single layer on a baking sheet, then transfer to a freezer-safe bag or container. When you're ready to enjoy, just thaw at room temperature or microwave for a few seconds. They’re perfect to make in batches and grab on the go!
