Banana Protein Oat Bake

Great for breakfast, this Banana Protein Oat Bake is also a wonderful lunch or snack. It’s flavored with bananas, cinnamon, and Allulose, a sugar-free calorie-free sweetener. You can also flavor it with different flavors of protein powder, such as vanilla, chocolate, or pumpkin spice. Additionally, you have the option of adding fresh berries or chopped walnuts.

I love adding this Banana Protein Oat Bake to my brunch table.

It’s a healthy option that fills you up while still tasting like yummy normal food.

Add in some berries for color and additional sweetness, or go with a little crunch by adding walnuts.

Then again, there’s nothing stopping you from adding them both.

Making Banana Protein Oat Bake

Using a large bowl and a medium bowl, mix all the wet ingredients in the large bowl, and yes, you guessed it, mix all the dry ingredients in the medium bowl.

Add the dry ingredients to the wet and stir until mixed thoroughly.

If you want to add some chopped walnuts, berries, or both, now would be the time.

Another idea I still have to try is diced apples with the walnuts…doesn’t that sound good?

Pour the mixture into a greased 9″ x 9″ baking dish and preheat your oven to 350°.

You can also use an 8″ x 8″ dish, only bake it a little longer. The middle will be a little thicker (deeper) so it takes a bit longer in the oven, maybe 3 – 5 minutes more is all.

Before removing from the oven, take a butter knife and check the middle. If it’s still runny, leave it for another few minutes.

For this recipe I added blueberries to one half, strawberries to the other half. I wanted to see how each tasted.

The berries were added after pouring the mixture into the baking dish. I did this so I could better control where the berries went.

I sprinkled them on top, then poked them down with a spoon so they weren’t all on top.

I’m thinking this would be fun for a Fourth of July brunch, Labor Day, or Memorial Day. What do you think?

Add the blueberries in the top left corner, then stripe the strawberries from left to right to give it a flag effect.

If anyone tries this, post a picture in Pinterest so we can all see.
