Preparation Guide

Mixing Ingredients

To prepare no-bake peanut butter oatmeal bars, start by gathering all your ingredients, including creamy peanut butter, a sweetener like honey, and old fashioned oats. You may also add optional ingredients like vanilla extract, salt, or other add-ins like chocolate chips or dried fruits.

Begin by heating a medium saucepan over medium heat. Combine the creamy peanut butter and honey, stirring until they are well combined and have a smooth consistency. If using, you can also add in the vanilla extract and salt at this stage. Once everything is well-mixed, remove the saucepan from heat and gradually stir in the old fashioned oats. Keep stirring until all the oats are evenly coated.

Setting and Cutting

Prepare an 8-inch square baking pan by lining it with parchment paper. Transfer the peanut butter oat mixture into the lined pan, pressing it down firmly into an even layer, ensuring that it spreads uniformly across the pan.

Next, you will need to let your bars set. You can either refrigerate the pan for about 1-2 hours, or freeze it for 30 minutes to an hour. This will help the bars solidify and become easier to cut.

After the bars have set, use the edges of the parchment paper to lift the entire block out of the baking pan. With a sharp knife, cut the block into desired bar sizes or squares. You can enjoy these no-bake oatmeal peanut butter bars immediately, or store them in an airtight container. If not consuming immediately, you can refrigerate them for up to a week, or freeze them for up to a month in a freezer-safe container.

These bars make a versatile and quick breakfast option or a healthy snack throughout the day. With minimal prep time, you can easily whip up a batch for a delicious and nutritious treat. Enjoy your no-bake peanut butter oatmeal bars as they are, or get creative and add them to yogurt, granola, or a smoothie bowl.

Storage Tips

Taking proper care of your no-bake peanut butter oatmeal bars is essential to ensure they remain a delicious and convenient sweet treat. To help you store your bars effectively, we have provided some storage tips, focusing on both refrigeration and freezing.


Storing your no-bake peanut butter oatmeal bars in the fridge is a great option if you plan to enjoy them within a week. To store the bars in the fridge, follow these steps:

  1. Place the bars in an airtight container to protect them from moisture and external odors.
  2. If the bars have a chocolate drizzle, separate each layer with a piece of parchment paper or plastic wrap to prevent them from sticking together.
  3. Store the container in the refrigerator for up to 7 days for easy grab-and-go breakfasts or snacks.

Keep in mind: Storing the bars in the fridge can make them firmer than room temperature, so let them sit at room temperature for a few minutes before eating for a softer texture.


If you want to store your no-bake peanut butter oatmeal bars for a longer period, freezing them is an excellent choice. Here’s how you can freeze your bars:

  1. Wrap each bar individually in plastic wrap or place them in a resealable plastic bag to prevent freezer burn.
  2. Label the container or bag with the date and contents for future reference in your freezer.
  3. Freeze the bars for up to 3 months. To thaw, place them in the refrigerator overnight or at room temperature for a few hours.

By following these storage tips, your no-bake peanut butter oatmeal bars will be ready to savor whenever you need a quick, tasty treat or a healthy grab-and-go breakfast option.
