Measure Ingredients – Pre-measure all ingredients. Unwrap caramels and keep them on parchment paper to prevent sticking.
Make Popcorn – Heat coconut oil in the Whirly Pop on medium. Add popcorn kernels once melted. Turn the crank until popping slows, then remove from heat. Pour onto a parchment-lined sheet and remove unpopped kernels. Transfer to a bowl.
Preheat Oven – Set oven to 200°F.
Make Caramel – Melt butter in a large stockpot over medium heat. Add brown sugar and stir until combined. Quickly add Werther’s caramels, stirring to prevent burning. Scrape the pan bottom regularly.
Add Baking Soda – Once caramels are melted, add baking soda. Stir until it dissolves and becomes puffy (about 30 seconds). Remove from heat immediately.
Coat Popcorn – Quickly stir popcorn into the caramel mixture until evenly coated. Spread on a parchment-lined baking sheet.
Bake – Bake at 200°F for 12-15 minutes, turning every 6 minutes to avoid burning.
Cool and Serve – Let popcorn rest on the sheet for 1 hour uncovered. Break up clusters if needed. Serve once crisp.
Notes
Work quickly when mixing caramel to prevent burning.Ensure popcorn is fully cooled before storing to maintain crispiness.Use a deep stockpot to allow space for stirring without spilling.Prepping caramels ahead of time makes the process smoother.
