Ingredients

  • 2 c. peanut butter
  • 1/2 c. water
  • 1 3/4 c. sugar
  • 1/2 c. Karo syrup (light)

Instructions

  1. Spread peanut butter into a nonstick skillet.
  2. Cook sugar, water, and Karo syrup together until reaching 300°F (hard crack stage).
  3. Pour the hot syrup mixture over the peanut butter and mix until well combined.
  4. Pour the mixture into a greased or parchment-lined surface and spread evenly.
  5. Cut into pieces while still warm and allow to cool completely before serving.

Tips & Substitutions

To ensure the peanut butter hard tac sets properly, use a candy thermometer to accurately measure the temperature of the syrup mixture. If you prefer a sweeter version, consider using honey instead of Karo syrup. If you want a nut-free option, replace peanut butter with sun butter for similar consistency. For added flavor, you might stir in a pinch of salt or vanilla extract before pouring over the peanut butter.

Serving Suggestions

Cut the peanut butter hard tac into bite-sized pieces for easy snacking. It pairs beautifully with a cup of hot cocoa or coffee for a delightful treat. For a fun twist, try serving it alongside sliced fruits or as part of a dessert platter with items like Soft Molasses Cake or Tylene'S Oatmeal Cookies for a sweet variety.

Storage & Reheating

Store the peanut butter hard tac in an airtight container at room temperature for up to two weeks. If the climate is humid, consider refrigerating it to prevent stickiness. To reheat, simply place it in a microwave-safe dish for a few seconds to soften slightly, making it easier to cut if it has hardened.

Frequently Asked Questions

Can I use natural peanut butter for this recipe?

Yes, you can use natural peanut butter, but keep in mind that it may have a different texture and flavor compared to conventional peanut butter. Natural varieties can be more oily, so stirring may be required to combine the oils before spreading.

What should I do if my syrup doesn't reach the hard crack stage?

If your syrup doesn't reach 300°F, it won't set properly. You can continue cooking the mixture while monitoring the temperature closely. Alternatively, if it sets too soft, you can reheat it again to reach the correct temperature, ensuring it hardens as intended.

How can I make this recipe more chocolaty?

To add a chocolaty flavor, you can mix in cocoa powder or melted chocolate with the peanut butter before pouring the syrup over it. This addition will create a delicious chocolate-peanut butter flavor combination that's hard to resist!
