Gather your ingredients
To start this delightful cookie-making adventure, you’ll need just three simple ingredients. These are not only easy to find but are likely already in your pantry!
- 2 ripe bananas: Look for bananas that are spotty and sweet — this is when they’re perfect for baking.
- 1 cup of peanut butter: You can choose creamy or crunchy based on your texture preference.
- 1 cup of old-fashioned oats: The oats add a lovely chewiness and make these cookies feel wholesome.
Once you’ve gathered these ingredients, you’re off to a great start!
Mash the ripe bananas
Now that you have your ingredients, it’s time to take those ripe bananas and mash them up. This is the part where, honestly, you can release just a little bit of stress. Grab a fork and get to work! Aim for a smooth consistency, but don’t worry if there are a few small lumps. These bananas add moisture and sweetness to your cookie dough, enhancing the flavor in the process.
Did you know that ripe bananas contain more antioxidants than their non-ripe counterparts? It’s a great excuse to enjoy bananas that might be past their prime but perfect for baking!
Combine peanut butter and bananas
In a mixing bowl, combine your mashed bananas with the peanut butter. Stir these two delicious ingredients together until you have a smooth, cohesive mixture. This step is crucial because it ensures that the flavors meld beautifully, giving your cookies that classic peanut butter-banana taste.
When combining these ingredients, you might find yourself reminiscing about Grandma’s cozy kitchen, with the tempting smell of peanut butter wafting through the air. It’s moments like these that make cooking feel warm and nostalgic.
Stir in the old-fashioned oats
Next, it’s time to add in the old-fashioned oats. Gently fold them into your peanut butter and banana mixture. Make sure the oats are evenly distributed — they will hold the cookies together and add a delightful texture.
Pro tip: If you want to jazz up your Grandma’s 3-Ingredient Peanut Butter Banana Cookies, consider adding a handful of chocolate chips, nuts, or dried fruit at this stage!
Scoop and shape the cookies
Now comes the fun part: scooping and shaping! Using a cookie scoop or a tablespoon, drop spoonfuls of dough onto a baking sheet lined with parchment paper. Leave some space between each cookie, as they will spread slightly while baking.
If you want your cookies to look extra special, you can gently flatten them with the back of a fork or your hands, giving them that classic cookie shape.
Bake to perfection
Preheat your oven to 350°F (175°C) and pop those cookies in for about 10-12 minutes. Keep an eye on them — they’re done when the edges are lightly golden and the centers look set.
Once baked, allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack. The aroma filling your kitchen is sure to have everyone asking what’s for dessert!
Enjoy these Grandma’s 3-Ingredient Peanut Butter Banana Cookies fresh or store them in an airtight container for up to a week. You might even consider making a double batch to share with friends or as a healthy snack option. So, who will you share these delightful cookies with first?
