Recipe Tips for Success
- Do not over-bake them, or they will turn out dry. So keep an eye on them after 20 minutes in the oven. All ovens vary; the baking time is an estimate.
- These muffins are not overly sweet, but loaded with enough blueberries, and the crumble and/or lemon icing (whichever one you choose) will give the additional sweetness needed.

Directions To Make Blueberry Lemon Oat Muffins:
As a reminder, our full recipe card is located at the bottom. But first, let’s run through our easy-to-follow steps so you can understand what’s involved before you begin.
1. Preheat oven to 375 degrees F (190.6C). Arrange the racks in the oven so that one is in the center.
2. In one large mixing bowl, beat or whisk oil, eggs, and sugar until the sugar is creamy smooth and not lumpy. Then whisk in vanilla, milk, baking powder, baking soda, salt, lemon zest, and lemon juice.
3. Whisk in the flour, one cup at a time. Use a wooden spoon or spatula to stir in the old-fashioned oats, and then the blueberries.

4. Divide the mixture into 12-muffin paper liners.
5. Then TURN DOWN the oven temperature to 350 degrees F (176.7°C). (see my notes below)…

6. BAKE on the center rack (at 350 degrees), for 25 to 30 minutes. Remove from the oven and allow them to cool on a wire rack. Store in a sealed container.
How to get Higher Tops on these muffins?
- For higher tops with these muffins, it’s best to preheat your oven to 375 degrees F (190.6C °C), while whipping up the batter for them.
- Then, reduce the oven temperature to 350 degrees F (176.7 °C) before you bake them.
- Next, place the muffin pan on the center rack in your oven. This will give them an extra jump-start to make them bake higher in appearance.
What’s the difference between a Muffin and a Cupcake?
- Muffin: is considered a breakfast item, like a mini quick bread and it’s usually topped with a crumble. It can be simple or made with additional ingredients, such as fruits, nuts, and even vegetables.
- The Cupcake: is considered a dessert. It is a “mini cake” usually topped with a sweet frosting.
Storing and Freezing
Muffins can be stored at room temperature, lightly covered, or kept in a cake plate with glass cover. These muffins are easy to freeze, too. Be sure they cool completely before storing and freezing. Transfer the muffins in an air-tight container, then freeze. They will stay fresh for up to 2 months. Then allow them to thaw on your counter before serving them.
