Ingredients
To get started on your 5-Ingredient Peanut Butter Oatmeal Cookies, you’ll need the following ingredients:
- 1 cup peanut butter (creamy or chunky based on preference)
- 1 cup granulated sugar
- 1 egg (room temperature)
- 1 cup rolled oats
- 1 teaspoon vanilla extract (optional, but recommended)
Step-by-Step Instructions
- Preheat the Oven
Preheat your oven to 350°F (175°C). This helps to ensure your cookies bake evenly. - Mix the Ingredients
In a large mixing bowl, combine the peanut butter and granulated sugar. Mix them together until well incorporated. Next, add the egg and vanilla extract (if using), stirring until it’s smooth. Finally, fold in the rolled oats gently until combined. - Shape the Cookies
Using a tablespoon or cookie scoop, drop the cookie dough onto a baking sheet lined with parchment paper, leaving enough space between each dough ball for spreading. - Bake
Place the baking sheet in the preheated oven and bake for about 10 minutes or until the cookies are golden brown around the edges. - Cool Down
Once baked, remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.
Top Tips for Perfecting 5-Ingredient Peanut Butter Oatmeal Cookies
- Peanut Butter Choices: For a creamier texture, use creamy peanut butter, but if you love crunch and texture, go for chunky peanut butter.
- Sugar Alternatives: If you’re looking for a healthier option, you can substitute granulated sugar with coconut sugar or maple syrup, adjusting the quantities accordingly.
- Texture Control: Don’t overmix the oat dough; a little bit of mixing will ensure those chewy bits don’t overly disappear!
- Watch the Oven: Keep an eye on them while baking; due to oven variances, the cooking time might slightly differ.
Storing and Reheating Tips
To keep your 5-Ingredient Peanut Butter Oatmeal Cookies fresh, store them in an airtight container at room temperature for up to 5 days. If you’d like to enjoy them later, consider freezing them—place them in a single layer in a freezer-safe bag or container for up to 3 months. When you’re ready to enjoy a cookie, simply reheat it in the oven at 350°F (175°C) for about 5 minutes to regain that freshly baked texture.
