Ingredients

  • 1 cup sugar
  • 3/4 cup rolled oats
  • 4 tablespoons peanut butter
  • 1/4 teaspoon salt
  • 1/2 teaspoon baking soda

Instructions

  1. Combine oats, peanut butter, salt, and baking soda in a bowl.
  2. Put sugar in a heavy skillet over moderate heat.
  3. Stir constantly with a wooden spoon until the sugar melts and turns a caramel brown color.
  4. Remove from heat and quickly add the peanut butter, oats, salt, and baking soda.
  5. Pour the mixture into a well-greased baking sheet.
  6. Spread with a spatula into thin pieces and let cool before breaking into pieces.

Tips & Substitutions

For a chewier texture, consider reducing the baking soda slightly. If you want a nut-free version, substitute the peanut butter with sunflower seed butter. Ensure you stir the sugar constantly to prevent burning, and use a heavy skillet for even heat distribution. You can add a pinch of cinnamon for an extra flavor twist.

Serving Suggestions

Peanut Butter Oat Brittle makes a delightful snack on its own or can be crumbled over yogurt for a crunchy topping. It pairs beautifully with a warm cup of tea or coffee. You can also serve it alongside fresh fruit or a creamy Dip For Sliced Apples for a fun dessert platter.

Storage & Reheating

Store the cooled brittle in an airtight container at room temperature for up to two weeks. To keep it fresh and prevent sticking, you can layer pieces between sheets of parchment paper. If it becomes too hard, you can microwave it for a few seconds to soften slightly before enjoying.

Frequently Asked Questions

Can I use a different type of nut butter?

Yes, you can substitute peanut butter with almond butter, cashew butter, or any nut butter of your choice. Just keep in mind that the flavor and texture may vary slightly depending on the nut butter used.

What should I do if my sugar hardens before mixing?

If the sugar hardens, you can gently reheat it over low heat until it softens again. Be careful not to burn it; stir constantly to achieve a smooth caramel consistency before adding the other ingredients.

Can I add other ingredients for variation?

Absolutely! Feel free to mix in some chopped nuts, dried fruits, or chocolate chips for added flavor and texture. Just be sure to adjust the quantity of oats if you add more ingredients to maintain the right balance.
