Make the best sweet and salty snack with this simple recipe for homemade butter toffee pretzels. Achieve a shatteringly crisp texture perfect for parties, holidays, or edible gifts.

Ingredients

Scale
  • 1 bag (16 ounces) mini pretzel twists
  • 1 cup (2 sticks) unsalted butter
  • 1 cup packed light brown sugar
  • 1 teaspoon vanilla extract
  • 1 teaspoon baking soda

Instructions

  1. Preheat your oven to 250 degrees Fahrenheit. Line two large baking sheets with parchment paper. Spread the mini pretzel twists in a single layer on the prepared sheets.
  2. In a medium saucepan, combine the butter and brown sugar. Heat over medium heat, stirring constantly until the butter is melted and the sugar is completely dissolved. Bring the mixture to a full, rolling boil. Let it boil for exactly one minute without stirring.
  3. Remove the saucepan from the heat immediately. Stir in the vanilla extract. Then, quickly stir in the baking soda. The mixture will foam up significantly.
  4. Working quickly, pour the hot toffee mixture evenly over the pretzels on both baking sheets. Use a spatula to gently toss the pretzels until they are fully coated.
  5. Bake the coated pretzels for 15 minutes. Remove the sheets from the oven and gently stir the pretzels to ensure even coating and baking. Return them to the oven and bake for another 15 minutes.
  6. Remove the pretzels from the oven. Let them cool completely on the baking sheets without touching them. As they cool, the toffee coating will harden and become crisp.
  7. Once fully cooled and hard, break apart any large clusters. Store in an airtight container.

Notes

  • For extra flavor, substitute half of the butter with salted butter.
  • If you want a glossy finish, you can sprinkle a small amount of sea salt over the pretzels immediately after removing them from the oven.
  • This recipe works best with mini pretzel twists for maximum coating surface area.
