These buttermilk oatmeal raisin muffins are a delightful treat for breakfast or a snack. They are moist, flavorful, and packed with the goodness of oatmeal and raisins. The buttermilk adds a tangy richness that perfectly complements the sweetness of the brown sugar.
If you don't usually have buttermilk in your fridge, you might need to pick some up at the supermarket. It's a key ingredient that adds a unique tang and moisture to the muffins. Additionally, make sure you have oatmeal and raisins on hand, as these are essential for the texture and flavor of the muffins.

Baking powder: Helps the muffins rise and become fluffy.
Baking soda: Works with the buttermilk to leaven the muffins.

Suggested Side Dishes
Alternative Ingredients
oatmeal - Substitute with quinoa flakes: Quinoa flakes provide a similar texture and are also gluten-free, making them a good alternative for those with gluten sensitivities.
buttermilk - Substitute with milk and lemon juice: Mix 1 cup of milk with 1 tablespoon of lemon juice or vinegar and let it sit for 5-10 minutes. This mixture mimics the acidity and thickness of buttermilk.
raisins - Substitute with dried cranberries: Dried cranberries offer a similar chewy texture and sweetness, adding a slight tartness that complements the muffin flavor.
all-purpose flour - Substitute with whole wheat flour: Whole wheat flour adds more fiber and nutrients, though it may make the muffins slightly denser.
brown sugar - Substitute with coconut sugar: Coconut sugar has a lower glycemic index and provides a similar caramel-like flavor to brown sugar.
baking powder - Substitute with baking soda and cream of tartar: Use ¼ teaspoon of baking soda and ½ teaspoon of cream of tartar for every teaspoon of baking powder needed.
baking soda - Substitute with baking powder: Use 3 teaspoons of baking powder for every teaspoon of baking soda, but omit any acidic ingredients like buttermilk.
salt - Substitute with sea salt: Sea salt can be used in the same quantity and provides a slightly different mineral content and flavor.
egg - Substitute with flaxseed meal and water: Mix 1 tablespoon of flaxseed meal with 3 tablespoons of water and let it sit for a few minutes to thicken. This mixture acts as a binding agent similar to eggs.
vegetable oil - Substitute with applesauce: Unsweetened applesauce can replace vegetable oil to reduce fat content while keeping the muffins moist.
vanilla extract - Substitute with almond extract: Almond extract provides a different but complementary flavor profile, adding a nutty undertone to the muffins.

How to Store or Freeze These Muffins
Allow the buttermilk oatmeal raisin muffins to cool completely on a wire rack before storing. This prevents condensation from forming inside the storage container, which can make the muffins soggy.
For short-term storage, place the muffins in an airtight container. Line the bottom of the container with a paper towel, arrange the muffins in a single layer, and place another paper towel on top before sealing. This helps absorb any excess moisture.
Store the container at room temperature for up to 2 days. If you need to keep them fresh for a longer period, consider refrigerating them. In the fridge, they can last up to a week.
To freeze the muffins, first wrap each muffin individually in plastic wrap or aluminum foil. This prevents freezer burn and helps maintain their texture.
Place the wrapped muffins in a resealable freezer bag or an airtight container. Label the bag or container with the date to keep track of how long they've been stored.
Freeze the muffins for up to 3 months. When you're ready to enjoy them, thaw the muffins at room temperature or reheat them directly from the freezer.
To reheat, preheat your oven to 350°F (175°C). Place the muffins on a baking sheet and heat for about 10 minutes, or until warmed through. Alternatively, you can microwave them on a microwave-safe plate for about 20-30 seconds.
If you prefer a crispier texture, you can also toast the muffins in a toaster oven. Slice them in half and toast until the edges are golden brown.
For an extra touch of flavor, consider spreading a bit of butter or cream cheese on the warm muffins before serving.
How to Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the buttermilk oatmeal raisin muffins on a baking sheet and cover them loosely with aluminum foil to prevent drying out. Heat for about 10 minutes or until warmed through. This method helps maintain the muffins' original texture.
Microwave Method: Place a muffin on a microwave-safe plate. To keep it moist, you can place a small cup of water in the microwave alongside the muffin. Heat on medium power for 20-30 seconds. Check if it's warm enough; if not, continue heating in 10-second intervals.
Toaster Oven Method: Preheat your toaster oven to 350°F (175°C). Place the muffins directly on the rack or on a baking sheet. Heat for about 5-7 minutes. This method gives a slightly crisp exterior while keeping the inside moist.
Steaming Method: If you want to retain maximum moisture, you can steam the muffins. Place them in a steamer basket over boiling water and cover. Steam for about 5 minutes. This method is great for keeping the muffins soft and moist.
Air Fryer Method: Preheat your air fryer to 320°F (160°C). Place the muffins in the basket, ensuring they are not touching each other. Heat for about 3-5 minutes. This method is quick and gives a slightly crispy exterior.
Stovetop Method: If you don't have access to an oven or microwave, you can use a stovetop. Place the muffins in a skillet over low heat. Cover the skillet with a lid to trap the heat and moisture. Heat for about 5 minutes, flipping halfway through to ensure even warming.
