The addition of yogurt makes all the difference

Adding yogurt to these Oatmeal Muffins helps make them tender, flavorful, and nutritious. siggi’s simple ingredient skyr yogurt, which is similar to the thickness of Greek yogurt, is the secret ingredient in these delicious Blueberry Oatmeal Muffins. We love to use siggi’s yogurt because it is made with simple ingredients and a lot less sugar than most yogurts. Not only does adding siggi’s simple ingredient skyr vanilla yogurt make the texture of these muffins extra tender and deliciously moist, it also helps to boost the overall protein content and creates a lighter muffin, making a single muffin the perfect addition to a nutritious breakfast or healthy snack.

siggi’s is versatile and nutritious substitution in a variety of recipes, not just in these muffins!

The thicker texture and protein in siggi’s yogurts makes it the perfect ingredient in many types of recipes. Here are some of our favorite ways to swap and substitute with siggi’s simple ingredient skyr yogurt:

1 tablespoon sour cream = 1 tablespoon siggi’s plain yogurt1 tablespoon of mayo = 1 tablespoon siggi’s plain yogurt1 cup oil = 3/4 cup siggi’s plain yogurt1 cup cream cheese = 1/2 cup siggi’s plain yogurt + 1/2 cup cream cheese1 cup buttermilk = 2/3 cup siggi’s plain yogurt + 1/3 cup milk 1 cup butter = 1/2 cup siggi’s plain yogurt + 1/2 cup butter

How to store Blueberry Oatmeal Muffins

Store the baked and cooled muffins in an airtight container in the fridge for up to 5 days. We recommend reheating for 15-30 seconds in the microwave. You can freeze the baked muffins for longer storage, up to 3 months.

Can I use Frozen Blueberries in Muffins

Yes, with most recipes that call for fresh fruit, you can substitute frozen fruit, and these muffins are no exception. If using frozen berries, there’s no need to thaw them. We recommend adding the frozen blueberries directly to the batter and folding them in very gently.

Can you use mashed banana instead of applesauce in this recipe

Yes, you sure can. Mashed banana can almost always be used as a substitute for applesauce in baked good recipes. So, if you don’t have applesauce on hand or you want to turn this recipe into a Banana Blueberry Oatmeal Muffins, then simply substitute 1 mashed banana (about a 1/2 cup) for the applesauce in this recipe.
