Preheat oven to 200° F. Line two large rimmed baking trays with parchment paper. Spray lightly with non-stick spray.
Over medium heat add the butter to a medium sized sauce pan. Stir in the brown sugar, corn syrup, brown sugar and salt.
Occasionally stir and watch the butter mixture to start to bubble. Start timer for 5 minutes and continue to stir.
Once the mixture has boiled for 5 minutes, remove from heat and stir in the baking soda. You will see a reaction as the toffee will thicken.
Working quickly pour the toffee over the pretzels while stirring to coat as evenly as possible.
Spread over 2 baking sheets and place in preheated oven. Sprinkle half of the Healthy Bits over the pretzels. Bake for 1 hour, stirring every 15 minutes. This will help evenly coat the pretzels with the toffee.
Remove from oven and sprinkle the remaining Health Bits over the pretzels. Break up any large clumps. Allow to cool for an hour at room temperature.
Do not store until completely cooled. Store in an airtight container.
