Make-Ahead Oatmeal Breakfast Bars

I’m always trying to find new ideas for breakfast, it’s our least exciting meal of the day here. Typically we all just have a quick bowl of cereal. Every now and then we go wild and have some oatmeal!

So I started looking online for other recipes that we could do that don’t take too long in the morning. I came across a recipe for fruit oatmeal bars and figured we would give it a try! We were skeptical at first, but they were really good and we have made them a few times since then. They keep in the refrigerator really well so we can just grab them out in the morning, which is my kind of breakfast!

If you are using frozen fruit for this recipe, make sure it is completely thawed before cooking. You can also substitute other fruits as desired. Strawberries, blueberries, and bananas are our fruits of choice here.

One of the best parts about this breakfast is the make-ahead aspect. I like to make these bars in the evening when I have a little bit more time, then they are ready in the morning for breakfast. You can eat them cold straight from the refrigerator, or warm them in the microwave. I like to reheat mine for about 10 seconds, just enough to take the chill out, but still have a cold breakfast.

I haven’t tried it yet, but T has asked if I could pack one in his lunchbox the next time we make them. Since they are good warm or cold, I don’t see why they wouldn’t still be good by lunchtime, especially if you send a freezer pack in their lunchbox like I usually do.

Start by preheating your oven to 375 and generously spray a 9×13 pan with cooking spray. I learned the hard way the first time I made this recipe that they will stick to the edges if you don’t have enough grease in there. In a large bowl, mix your oats, brown sugar, baking powder, cinnamon, salt, half of the chocolate chips, and half of the fresh berries.

Slice both of the bananas and layer that on top of the mixture without overlapping and covering as much of the mixture as possible.

In a medium mixing bowl, whisk the milk, egg, butter, and vanilla extract. Pour the egg mixture over the berries, ensuring that the oats are evenly soaked.

Bake the oatmeal bars for about 30 minutes. Remove from the oven and sprinkle 1-2 tbsp of brown sugar over the entire dish. Bake for an additional 10 minutes or until the top of the casserole is golden brown.

Allow the bars to cool for a few minutes before cutting. Store in the refrigerator and enjoy for a few days.
