Ingredients

  • 4 cups oatmeal
  • 1 cup brown sugar
  • 1/4 cup corn syrup
  • 2/3 cup melted margarine
  • 1/4 cup chunky peanut butter
  • 1 teaspoon vanilla

Instructions

  1. Mix the oatmeal, brown sugar, corn syrup, melted margarine, chunky peanut butter, and vanilla in a bowl.
  2. Pat the mixture into a greased 13-inch pan evenly.
  3. Bake at 400°F for 12 minutes, until edges are brown.
  4. Remove from oven and let cool slightly; the middle will not be set but the bars will firm up as they cool.
  5. Cut the bars while still warm and allow to cool completely in the pan before serving.

Tips & Substitutions

For added flavor and texture, consider mixing in nuts or dried fruits to the base; almonds or cranberries work well. If you prefer a vegan option, substitute the margarine with coconut oil and use a plant-based sweetener instead of brown sugar. Ensure to pack the mixture tightly in the pan for better structure. To make them chewier, slightly reduce the baking time.

Serving Suggestions

These bars make a perfect on-the-go snack or a post-workout treat. Pair them with a glass of almond milk or your favorite smoothie for a nutritious breakfast. They also complement a sweet dessert like Aunt Bessie'S Pound Cake for an indulgent afternoon treat. Cut them into smaller squares to share at gatherings or picnics.

Storage & Reheating

Store the Peanut Butter Trail Mix Bars in an airtight container at room temperature for up to a week. For longer storage, refrigerate them, where they can last for two weeks. If you want to enjoy them warm, simply microwave for a few seconds to soften before serving.

Frequently Asked Questions

Can I use rolled oats instead of instant oats for this recipe?

Yes, rolled oats can be used in place of instant oats. They will provide a heartier texture, making the bars more substantial. Just ensure to bake them a bit longer if the mixture appears too soft.

What can I substitute for corn syrup?

If you want to avoid corn syrup, honey or maple syrup can be great alternatives. Keep in mind that these substitutions may slightly alter the flavor and sweetness of the bars.

Can I freeze these bars?

Absolutely! These bars freeze well. Wrap them individually in plastic wrap or foil and store in a freezer bag. They can last for up to three months in the freezer. Thaw at room temperature or microwave for a quick snack.
