Ingredients

For the base:

  • 1 c. unsalted butter
  • 1 c. granulated sugar
  • 1/2 c. brown sugar packed
  • 1 tsp. coarse kosher sea salt
  • 2 tbsp. water
  • 1 tbsp. light corn syrup
  • 1/4 c. chopped toasted nuts pecans, almonds, cashews, macadamia nuts

For the topping:

  • 6 oz. chopped chocolate or chocolate chips milk, semisweet, bittersweet or white
  • 1/4 c. chopped toasted nuts pecans, almonds, cashews, macadamia nuts
  • pinch flaky sea salt

Instructions

  • Line a baking sheet with silicone baking mat or parchment paper, set aside.
  • In a large glass microwave-safe bowl (4 quart is best), combine the butter, sugars, salt, water, and corn syrup.
  • Microwave for 3 minutes on HIGH.
  • Stir in chopped nuts.
  • Microwave for 8-10 minutes on HIGH or until it reaches 300 degrees F on an instant read or candy thermometer - pause the microwave cooking every 2 minutes and stir and check the temperature - do NOT overcook it, or it will burn.
  • Quickly pour and spread onto a silicone lined baking sheet into an even layer about 1/8-inch thick. 
  • Add the chocolate chips on top and let rest for 3 minutes so they can melt. Using an offset spatula, gently spread the melted chocolate over top. Sprinkle on nuts and sea salt.
  • Chill until set, about an hour. Break into pieces.

Notes

-My microwave is 1000 watts. If yours is lower, you may need to cook it for slightly longer (1-2 minutes). If yours is higher you may need to cook it for a minute less.
-I would not recommend doubling the batch, but instead making two separate batches.
