Step‑by‑Step Instructions for Banana Oatmeal Bars
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures that your Banana Oatmeal Bars will bake evenly and achieve that delightful golden-brown crust. While the oven heats up, you can gather your ingredients, making sure everything is ready for mixing.
Step 2: Mash the Bananas
In a large mixing bowl, take your ripe bananas and mash them thoroughly with a fork or potato masher until smooth. Aim for a creamy texture without any large chunks, as this will contribute to the moistness of the bars. The sweeter and more overripe the bananas, the better your bars will taste!
Step 3: Combine Ingredients
Now, add the rolled oats, honey or maple syrup, eggs, baking powder, and vanilla extract to the mashed bananas. Using a spatula or wooden spoon, mix everything together until the ingredients are evenly combined. You want a consistent batter that showcases the beautiful blend of flavors found in these Banana Oatmeal Bars.
Step 4: Prepare the Baking Dish
Grab an 8×8-inch baking dish and either grease it lightly with cooking spray or line it with parchment paper for easy removal later. Ensuring your dish is well-prepared will prevent any sticking and help the bars come out perfectly shaped once they’re baked.
Step 5: Spread the Mixture
Pour the banana oat mixture into your prepared baking dish, spreading it evenly across the bottom. Use the spatula to smooth the top, ensuring it reaches all corners of the dish. This even distribution is key for achieving an equal bake and the ideal texture for your bars.
Step 6: Bake the Bars
Place the baking dish in the preheated oven and let the bars bake for 25 to 30 minutes. Keep an eye on them as they near the end of the baking time; they should turn a lovely golden brown and feel slightly firm to the touch. A toothpick inserted in the center should come out clean, signaling they’re ready.
Step 7: Cool and Cut
Once baked to perfection, remove the dish from the oven and allow the Banana Oatmeal Bars to cool for about 10 minutes. This cooling time helps them set and makes cutting easier. Once slightly cool, transfer them to a cutting board and slice them into squares to enjoy!
