Oatmeal Blueberry Muffins are wonderful to wake up with or to enjoy as a late night sweet treat! No matter what time of day you sneak a bite, you’re going to love these homemade muffins that are perfectly fluffy, slightly sweet, and loaded with bursting blueberries.
Homemade muffins are SO much better that the store-bought junk! Even the muffins from my grocery store’s bakery don’t quite hit the spot like I want them to. When I have a serious muffin craving, it’s homemade or nothing for me! Luckily, I have recipes like this one in my back pocket and ready to go.
Although they are made from scratch, these oatmeal blueberry muffins are pretty quick and easy to make. The ingredients here are simple and fuss-free, and you likely already have the majority (if not all of them) in your kitchen right now.
These muffins are an incredible to start your day off oh so right. They’re great for munching on when you need an quick on the go breakfast, or for when you want to take your time and savor your early morning with a touch of sweetness. Oh, and I eat them all the time for an after dinner dessert, too!
What You’ll Need
- Oats – For the best consistency, use old-fashioned rolled oats.
- Milk – Hot whole milk works best.
- Flour – All-purpose flour gives the muffins the best structure.
- Baking Powder and Baking Soda – These two things are NOT the same! Be sure to measure them both out with care, as they could each make or break the consistency of your muffins in different ways.
- Cinnamon – This adds a nice touch of warmth.
- Butter – Unsalted, melted, and slightly cooled.
- Sour Cream – Make sure it’s full fat! You can also opt for plain Greek yogurt as well.
- Eggs – They’ll need to be at room temperature.
- Vanilla Extract – Use pure extract, not imitation.
- Sugar – Just use plain white granulated sugar, nothing fancy.
- Brown Sugar – To make your own, simply combine one cup of white sugar with one tablespoon of molasses. Voila!
- Blueberries – They can be fresh or frozen.
How to Make Oatmeal Blueberry Muffins
Scroll to the bottom of this post for more detailed instructions.
Prep the oats. Combine the oats and hot milk. Let sit for about 15-20 minutes.
Make the batter. In one bowl, combine all of the dry ingredients except for the sugar. In another, combine the white and brown sugar with eggs. Add the wet ingredients to the egg mixture. Combine the wet and dry ingredients before folding in the blueberries and oats.
Bake. Divide the batter evenly into your prepared muffin pan and bake at 425°F for 6-7 minutes. Reduce the heat to 350°F and bake for another 12-15 minutes.
Cool. Allow the muffins to cool in the pan for 5 minutes, then transfer to a wire cooling rack.
How long will oatmeal blueberry muffins stay fresh? In an airtight container at room temperature, these muffins will stay fresh for about 2-3 days. In the fridge, they’ll last for up to 5 days. They also freeze well for up to 3 months!
Why do I have to start baking at a high heat? The initial higher heat of 425°F creates a burst of steam that lifts the batter perfectly. That way, your muffins will end up tall.
How to Serve Oatmeal Blueberry Muffins
Personally, I think these muffins are best when they’re still warm. Sometimes I zap mine in the muffin for about 30 seconds or so!
