How to Make the Recipe
Now, let’s get to the fun part—making these delicious bars!
- Preheat your oven to 350°F (175°C) and grease an 8-inch square baking pan.
- In a bowl, whisk together the flour, oats, baking powder, and salt. Set this mixture aside.
- In a large mixing bowl, use an electric mixer on medium speed to beat the softened butter, granulated sugar, and brown sugar until it’s light and fluffy. This step is crucial for that perfect texture!
- Add in the egg and vanilla extract, mixing well. Then, gently fold in the mashed bananas and peanut butter until just combined.
- Reduce the mixer speed to low and gradually add the flour mixture, mixing just until combined. Be careful not to overmix!
- Transfer the batter to your prepared pan and spread it evenly. Bake for 40-45 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean.
- Allow the bars to cool in the pan before cutting them into squares. Enjoy!
Pro Tips for Making the Recipe
Here are some of my favorite tips to ensure your Peanut Butter Banana Bars turn out perfectly:
- Make sure your bananas are very ripe for the best flavor and sweetness.
- For an extra touch, consider adding chocolate chips or chopped nuts to the batter.
- If you want to make these bars even healthier, you can substitute half of the all-purpose flour with whole wheat flour.
- Keep an eye on the baking time; ovens can vary, and you don’t want to overbake them!
How to Serve
These Peanut Butter Banana Bars are incredibly versatile! Here are a few serving suggestions:
- Enjoy them as a quick breakfast on the go.
- Pair them with a cup of coffee or tea for an afternoon snack.
- Serve them warm with a scoop of vanilla ice cream for a delightful dessert.
- Cut them into smaller pieces for a fun addition to lunchboxes!
Make Ahead and Storage
These bars are perfect for meal prep! Here’s how to store them:
- Store the bars in an airtight container at room temperature for up to 3 days.
- For longer storage, you can freeze them! Just wrap each bar individually in plastic wrap and place them in a freezer-safe bag. They’ll last up to 3 months in the freezer.
- To enjoy, simply thaw at room temperature or pop them in the microwave for a few seconds.
