Made from scratch and packed with fruit, whole-grain oats, and bright citrus notes, these muffins are both satisfying and flavorful. The oatmeal adds texture and heartiness while the banana and lemon brighten the batter. A light cinnamon-sugar sprinkle on top gives a touch of sweetness and a little crunch.

These muffins are great for busy mornings or an easy snack. A batch baked over the weekend will typically keep on the counter for up to three days. In hotter or more humid climates, store them in the refrigerator for up to five days to maintain freshness.

How to Freeze Blueberry Oatmeal Muffins

Cool muffins completely to room temperature before freezing. For best quality, place them in an airtight freezer bag and press out excess air, or use a rigid plastic container to protect the tops from being crushed. For both protection and minimal air exposure, you can set muffins in a container and then slip the container into a freezer bag.

Variations and Add-Ins

Blueberry muffins are highly adaptable. Add lemon zest for brightness, mash in an extra banana for sweetness and moisture, fold in chopped nuts for crunch, or increase oats for more whole-grain texture. A crumb topping or a light cinnamon-sugar sprinkle adds texture and a touch of sweetness.

Step-by-Step Method

1. Preheat the oven to 400°F. Prepare muffin tins with grease or liners.

2. Toss measured blueberries with 2 tablespoons of flour to coat; this helps prevent them from sinking in the batter.

3. In a mixing bowl, combine remaining flour, sugar, baking powder, salt, and old-fashioned oats. Slice cold butter into small pieces and cut it into the dry mix with a pastry cutter or fork until the butter pieces are the size of peas.

4. Stir in the mashed banana and lemon zest, then fold in the floured blueberries gently so they stay intact.
