Setup: Begin by preheating your oven to 350°F. Line a baking sheet with parchment paper to prevent sticking.
Layering the Base: Evenly spread the oyster crackers on the lined baking sheet.
Making the Caramel: In a saucepan, melt the butter over medium heat. Add brown sugar, vanilla, and cinnamon, and stir until the mixture dissolves. Allow this mixture to boil while you continue stirring. After 2-3 minutes, the caramel should thicken slightly and become a lighter shade.
Coating the Crackers: Remove the caramel from heat and quickly pour it over the oyster crackers. Gently mix until all the crackers are coated with the caramel goodness.
Baking: Sprinkle the coated crackers with salt. Bake them in the preheated oven for about 7-9 minutes. Keep a close eye on them to ensure the caramel does not burn.
Cooling and Storing: Once baked, let the crackers cool. They’ll become even crunchier as they cool. After cooling, break them into small clusters and store in an airtight container to maintain freshness
