📝 About This Recipe

A beloved staple of Mexican 'dulces típicos' (traditional sweets), Palanquetas are crunchy, golden peanut bars bound together by a rich caramel of piloncillo and honey. Originating from the heart of Mexico, these treats offer a perfect balance of salty, roasted nuts and deep, earthy sweetness. This recipe captures the nostalgic crunch and rustic charm found in the colorful markets of Mexico City and beyond.

🥗 Ingredients

The Nut Base

  • 3 cups Raw unsalted peanuts (skins removed for a cleaner finish)
  • 1/2 teaspoon Sea salt (to balance the sweetness)

The Caramel Binder

  • 250 grams Piloncillo (chopped or grated; can substitute with dark brown sugar)
  • 1/2 cup Granulated white sugar (helps with crystallization and structure)
  • 1/4 cup Honey (adds a floral note and prevents graininess)
  • 1/2 cup Water
  • 2 tablespoons Unsalted butter (at room temperature)
  • 1 teaspoon Vanilla extract (pure Mexican vanilla is best)
  • 1/4 teaspoon Baking soda (creates tiny air bubbles for a lighter crunch)

Preparation Essentials

  • 1 tablespoon Vegetable oil (for greasing the tray and spatula)

👨‍🍳 Instructions

  1. 1

    Preheat your oven to 350°F (175°C). Spread the raw peanuts on a large baking sheet in a single layer and toast for 8-10 minutes, shaking the tray halfway through, until they are fragrant and lightly golden. Set aside to cool.

  2. 2

    Prepare a 9x13 inch baking pan or a large marble slab by lining it with parchment paper and lightly brushing it with vegetable oil. This is crucial to prevent the sticky caramel from bonding to the surface.

  3. 3

    In a heavy-bottomed saucepan or a traditional copper 'cazo', combine the chopped piloncillo, white sugar, honey, and water over medium heat.

  4. 4

    Stir the mixture constantly with a wooden spoon until the piloncillo and sugar have completely dissolved and the liquid begins to bubble.

  5. 5

    Attach a candy thermometer to the side of the pot. Continue to simmer the syrup without stirring too much, allowing it to reach the 'hard crack' stage, which is 300°F (150°C). This usually takes 10-15 minutes.

  6. 6

    Once the temperature is reached, immediately remove the pan from the heat. Quickly stir in the butter, vanilla extract, and sea salt until well combined.

  7. 7

    Add the baking soda and stir vigorously. The mixture will foam up slightly and lighten in color; this ensures the brittle isn't too hard on your teeth.

  8. 8

    Swiftly fold in the toasted peanuts, ensuring every single nut is thoroughly coated in the amber caramel syrup.

  9. 9

    Pour the hot mixture onto your prepared baking sheet. Using a greased offset spatula or a second piece of oiled parchment paper on top, press the mixture down firmly into an even layer about 1/2 inch thick.

  10. 10

    Work quickly! While the mixture is still warm but starting to set (about 5 minutes after pouring), use a sharp, oiled knife to score the palanquetas into rectangles or squares.

  11. 11

    Allow the palanquetas to cool completely at room temperature for at least 1 hour until they are hard and brittle.

  12. 12

    Once fully set, snap the bars along the scored lines. Store them in an airtight container with parchment paper between layers to prevent sticking.

💡 Chef's Tips

Always use a candy thermometer for precision; the difference between chewy and crunchy is only a few degrees. If you cannot find piloncillo, use dark brown sugar with a tablespoon of molasses to mimic the deep flavor. Be extremely careful when working with hot sugar; keep a bowl of ice water nearby just in case of accidental splashes. Toasting the peanuts is non-negotiable—it releases the oils and provides the signature depth of flavor. If your kitchen is humid, the palanquetas may become sticky; store them in a very tight container immediately after cooling.

🍽️ Serving Suggestions

Serve alongside a steaming cup of Cafe de Olla for a truly authentic experience. Crumble leftovers over vanilla bean ice cream for a sophisticated Mexican sundae. Wrap individual bars in cellophane with a colorful ribbon for a charming homemade gift. Pair with a glass of cold milk to balance the intense sweetness and salty crunch. Include them on a dessert platter with other Mexican sweets like Ate de Membrillo and Cocadas.
