Preheat your oven to 350°F (175°C). This ensures your Salted Caramel Mini Crackers bake evenly.
Line your large baking sheet with parchment paper. Arrange the mini saltine crackers in a single layer, covering the entire surface of the sheet.
In a medium saucepan over medium heat, melt the butter. Once melted, stir in the brown sugar, vanilla extract, and ground cinnamon. Bring the mixture to a gentle boil, stirring constantly for about 3–4 minutes, or until the caramel thickens and becomes bubbly.
Carefully pour the hot caramel mixture over the arranged saltine crackers, using a spatula to spread it evenly. Make sure every cracker is covered for maximum flavor.
Place the baking sheet in the preheated oven and bake for 10 minutes. Keep a close eye on them to ensure the caramel doesn’t burn.
Remove the baking sheet from the oven and immediately sprinkle coarse salt over the hot caramel. The salt will stick nicely and enhance the flavor.
Allow the crackers to cool completely on the baking sheet. Once cooled, break them apart into pieces. Enjoy your Salted Caramel Mini Crackers!
