How to make carrot oat muffins
Here you’ll find instructions and step-by-step photos showing how to make this recipe. The full recipe, including ingredients, is given below.
Step 1: Preheat oven to 425°F. Grease 14 standard (2½-inch) muffin cups with nonstick cooking spray.

Step 10: Remove to a wire rack to finish cooling.

Recipe Tips!
- It’s important to properly measure the flours. Too much flour will give you dry or heavy muffins. Weighing the flour is the most accurate way to measure it, or you can sift or stir it to break it up, lightly spoon into a measuring cup, and level.
- Add-ins: Feel free to mix in 1/4-1/2 cup of chopped nuts or raisins.

Recipe FAQs
You can! Carrot oat muffins freeze well. Just bake the muffins as-directed and then let them cool to room temperature on a wire cooling rack. Wrap the muffins tightly in plastic wrap and place them in a freezer-safe container. Freeze for up to 3 months.
I haven’t used only whole wheat flour in this recipe. Whole wheat flour usually makes for heavier, denser baked goods, so using a half-and-half blend of all-purpose flour and whole-wheat flour helps to lighten up the muffins.

Storage
Store any leftover carrot oat muffins in an airtight container at room temperature. The muffins will keep for up to 3 days when properly stored.

Can I use all all-purpose flour. If so, do you think I would use 1 1/2 cups of all purpose or would I have to change the amount? I hate to have to buy whole wheat flour for only 3/4 cup.
Kate says
I haven’t tried using all all-purpose flour, but I would guess that it would work out just fine.
