Ingredients

  • 1/2 cup margarine
  • 1/2 cup Crisco
  • 1/3 cup peanut butter
  • 1 1/2 cups flour
  • 1/2 teaspoon vanilla
  • 3/4 cup peanuts
  • 2 cups sugar
  • 1 cup water

  2. Blend well at low speed until mixture is combined.
  3. Set aside.
  4. In a 1/2-quart saucepan, cook sugar and water to the hard-boil stage (250°F) or until syrup forms a ball when dropped in very cold water.
  5. Pour the hot syrup slowly over the butter and flour mixture.
  6. Stir until thickened and well blended.
  7. Pour the mixture into a buttered 11 x 7-inch pan.

Tips & Substitutions

For a richer flavor, consider using natural peanut butter instead of regular, and feel free to substitute half of the margarine with coconut oil for a tropical twist. If you prefer crunchier bars, add an extra 1/4 cup of chopped peanuts. Make sure to monitor the syrup closely as it cooks to avoid burning, as this can affect the texture of the bars.

Serving Suggestions

Cut the bars into squares or rectangles for easy serving. They pair beautifully with a glass of cold milk or a warm cup of coffee. For a delightful dessert spread, consider serving them alongside the Best Sweet Potato Casserole or Fudge Stripe Fruit Salad for a sweet contrast. These bars also make a great addition to lunchboxes or as a quick snack on the go.

Storage & Reheating

Store the no bake peanut bars in an airtight container at room temperature for up to one week. For longer storage, you can refrigerate them, which will help them stay fresh for up to two weeks. If you want to enjoy them chilled, simply take them out of the fridge about 10 minutes before serving to soften slightly.

Frequently Asked Questions

Can I use butter instead of margarine in this recipe?

Yes, you can substitute butter for margarine in this recipe for a more traditional flavor. Keep in mind that using butter may slightly alter the texture, but it will still yield delicious results.

How can I make these bars healthier?

To make these bars healthier, consider reducing the sugar by half and adding honey or maple syrup as a natural sweetener. You can also use whole wheat flour instead of all-purpose flour for added fiber and nutrients.

What can I do if the syrup doesn’t reach the hard-boil stage?

If your syrup doesn’t reach the hard-boil stage, it may not set properly. Try cooking it for a few more minutes and ensure it reaches 250°F, or test it by dropping a small amount into cold water to see if it forms a ball.
