Directions

Variations

You can easily customize these oatmeal breakfast bars to suit different tastes and dietary needs.

Swap blueberries with raspberries, chopped strawberries, or diced apples for a different fruit flavor. Add chopped nuts such as walnuts, pecans, or almonds for extra crunch and healthy fats. For a slightly sweeter treat, mix in a handful of dark chocolate chips.

To make the bars gluten-free, replace the whole wheat flour with a gluten-free flour blend and ensure the oats are certified gluten-free. You can also replace the egg with a flax egg if you prefer an egg-free version.

Storage/Reheating

Store the blueberry oatmeal bars in an airtight container in the refrigerator for up to 5 days. They also freeze very well, making them ideal for meal prep.

To freeze, wrap individual bars in parchment paper and store them in a freezer-safe container or bag for up to 3 months. When ready to eat, thaw overnight in the refrigerator or warm briefly in the microwave for about 15–20 seconds.
