Make these addictive butter toffee pretzels using a simple oven-baked method. This recipe delivers the perfect balance of salty crunch and rich, buttery brown sugar coating, ready in under 30 minutes.

Ingredients

Scale
  • 1 bag (12 ounces) mini pretzels
  • 1 cup (2 sticks) unsalted butter
  • 1 cup packed light brown sugar
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon baking soda

Instructions

  1. Preheat your oven to 250 degrees Fahrenheit. Line two large baking sheets with parchment paper.
  2. Spread the mini pretzels in a single layer across the prepared baking sheets. Do not let them overlap too much.
  3. In a medium saucepan, melt the butter over medium heat.
  4. Add the brown sugar to the melted butter. Stir constantly until the mixture comes to a full boil. Let it boil for exactly one minute, stirring continuously.
  5. Remove the saucepan from the heat immediately. Stir in the vanilla extract and the baking soda. The mixture will foam up.
  6. Quickly pour the hot toffee mixture evenly over the pretzels on the baking sheets. Use a spatula to gently toss the pretzels until they are coated. Work fast before the toffee hardens.
  7. Bake for 20 minutes, stirring the pretzels gently every 5 minutes to prevent sticking and ensure even coating.
  8. Remove from the oven and immediately spread the pretzels into a single layer again. Let them cool completely on the baking sheets. They will become crisp as they cool.
  9. Break apart any large clusters once fully cooled. Store in an airtight container.

Notes

  • For an extra layer of flavor, sprinkle a pinch of flaky sea salt over the pretzels right after they come out of the oven.
  • If you want a chocolate finish, drizzle melted semi-sweet chocolate over the cooled toffee pretzels before serving.
  • These are excellent for holiday gifts; package them in cellophane bags tied with a ribbon.
