01 - Preheat your oven to 350°F (175°C). Line a rimmed baking sheet, approximately 10x15 inches, with parchment paper or aluminum foil. Fold up the edges to create a slight border.
02 - In a single layer, arrange the salted saltine crackers to fully cover the bottom of the prepared baking sheet. Break crackers as needed to fill any gaps.
03 - In a medium saucepan, combine the unsalted butter and packed light brown sugar. Place over medium heat and stir constantly until the butter is melted and the sugar is dissolved. Bring the mixture to a boil and continue to cook for 3 minutes, stirring, until it thickens to a caramel consistency.
04 - Carefully and evenly pour the hot toffee mixture over the layer of saltine crackers. Use a spatula to spread the toffee to the edges, ensuring all crackers are coated.
05 - Place the baking sheet in the preheated oven and bake for 7–8 minutes, or until the toffee is bubbling.
06 - Remove the baking sheet from the oven. Immediately sprinkle the chocolate chips evenly over the hot toffee. Allow the chocolate to sit for 2–3 minutes to soften, then use an offset spatula or knife to spread the melted chocolate smoothly over the entire surface.
07 - While the chocolate is still soft, evenly distribute the chopped dried cherries, and maraschino cherries and toasted almonds if you are using them, over the chocolate layer. Gently press the toppings into the chocolate to help them adhere. Finish with a light sprinkling of flaky sea salt.
08 - Allow the confection to cool at room temperature for approximately 30 minutes. Then, transfer the baking sheet to the refrigerator for at least 30 minutes, or until the chocolate has fully set and hardened.
09 - Once firm, lift the entire sheet from the pan using the parchment or foil. Break the confection into desired pieces. Store in an airtight container in the refrigerator for up to one week.
