  • cups pecans chopped
  • 7 tablespoon butter divided (see instructions)
  • cups brown sugar
  • 3 tablespoon flour
  • ¾ cup light corn syrup
  • cup evaporated milk


  • **Bowls will be hot when microwaving. Remove from microwave with hot pads.
  • In a medium microwave-safe glass bowl, microwave pecans and 3 tablespoon of butter on high for 2-4 minutes, stirring every minute. **Watch carefully to not burn - nuts should smell toasted and butter will be brown. Once cooked, set aside to cool slightly.
  • In a separate, large microwave-safe glass bowl, melt remaining 4 tablespoon butter. Add brown sugar, flour, and light corn syrup. Whisk until smooth.
  • Microwave caramel mixture on high, whisking well once every minute, until the sugar is dissolved and the sauce is smooth. This step is highly dependent on your microwave. In mine it took 6-8 minutes to become truly smooth, but it may take more or less for you. Remove the sauce once it is smooth. **Watch carefully - it will boil over if in a small bowl!
  • Add pecan mixture and evaporated milk into the smooth caramel mixture. Mix thoroughly to combine. Serve warm or store for later use (see notes for storing instructions).


Tips & Tricks
  • The most important tip for success with this recipe is to watch everything carefully. Nuts burn easily and caramel boils over easily, so don’t walk away from the microwave. 
  • Use an extra large bowl for the caramel to avoid it spilling in your microwave. The less mess the better!
  • To avoid a grainy sauce, continue microwaving and whisking it frequently until all the sugar is dissolved. Check the sauce on the back of a spoon - it’s ready when it is smooth with no (or very few) small grains of sugar left.
Storing Instructions
Store in a jar or airtight container in the fridge for 2-3 weeks. Reheat in the microwave for 30-90 seconds, stirring every 30-45 seconds. 
Freezing Instructions
Freeze in a glass jar or airtight container, leaving a bit of empty space to allow the sauce to expand. Freeze for 2-3 months. Before serving, thaw overnight in the fridge. Reheat in the microwave until warm, stirring every 30-45 seconds.
