Ingredients

  • 2/3 cup butter or margarine
  • 1/4 cup peanut butter
  • 1 cup packed brown sugar
  • 1/4 cup light corn syrup
  • 1/4 teaspoon vanilla
  • 4 cups quick-cooking oats
  • 1 cup milk chocolate chips
  • 1/2 cup butterscotch chips

Instructions

  1. In a mixing bowl, combine the butter, 1/4 cup peanut butter, brown sugar, corn syrup, and vanilla; gradually add the oats. Press into a 13 x 9 inch baking pan.
  2. Bake at 400°F for 12 to 14 minutes or until edges are golden brown.
  3. Cool on wire rack for 5 minutes.
  4. Meanwhile, melt the chocolate chips and 1/3 cup peanut butter in the microwave for 1 minute.
  5. Stir until blended and spread over warm bars.
  6. Cool completely and refrigerate for 2 to 3 hours before cutting.

Tips & Substitutions

For a nuttier flavor, consider using crunchy peanut butter instead of creamy. If you're looking to reduce sugar, you can substitute half of the brown sugar with unsweetened applesauce. Adding a pinch of salt can enhance the sweetness. If you don't have quick-cooking oats, you can blend regular oats slightly for a similar texture. These bars are also great with some dried fruit mixed in.

Serving Suggestions

These peanut butter oat bars make a delightful snack on their own, but they pair beautifully with a glass of cold milk or a hot cup of coffee. For a fun twist, serve them alongside Chocolate Puffs for dessert. They also work well as a portable breakfast option or a post-workout treat, satisfying your sweet cravings healthily.

Storage & Reheating

Store leftover peanut butter oat bars in an airtight container at room temperature for up to a week. For longer freshness, refrigerate them for up to two weeks. To enjoy them warm, you can microwave individual bars for about 10-15 seconds, or until just warm, enhancing their rich flavors.

Frequently Asked Questions

Can I use other types of nut butter?

Yes, feel free to experiment with other nut butters like almond or cashew butter. Each will impart a different flavor to the bars. Just keep in mind that the consistency might vary slightly, so adjust the amount based on your preference.

What can I substitute for chocolate chips?

If you want to avoid chocolate, try using dried fruits such as cranberries or raisins for added sweetness and texture. You could also use chopped nuts, which will complement the peanut butter nicely.

Can I freeze these bars?

Absolutely! Once cut, wrap the bars individually in plastic wrap or foil, then place them in an airtight container or freezer bag. They can be frozen for up to three months. Just thaw them in the refrigerator overnight for a quick snack.
