The sweet, buttery flavours of these popular tarts combined with salty crackers and creamy chocolate make an addictive, utterly delicious treat that’s perfect for holiday candy making and gifting.
Preheat oven to 400ºF. Line bottom of a 17×11-inch rimmed baking sheet with parchment paper and arrange crackers in one layer on sheet (you may need to break some to fit), set aside.
In a medium saucepan over medium heat, combine butter, brown sugar, maple syrup and salt, stirring occasionally until the mixture comes to a boil. Boil for 8 minutes without stirring. Remove from heat and stir in vanilla. Carefully pour mixture immediately over crackers (it does need to completely cover the crackers as the mixture will spread in the oven).
Bake until butter and sugar mixture has spread over crackers and is bubbling, about 6 minutes. Remove from oven (rearrange crackers using a butter knife quickly if they shift at all during baking) and immediately sprinkle evenly to cover with chocolate chips; let stand 3 minutes, allowing chocolate to melt. Using an offset spatula or the back of a spoon, spread chocolate evenly over cracker mixture and sprinkle with pecans. Cool for 20 minutes at room temperature before transferring to the refrigerator to chill for at least 45 minutes, or until completely chilled through.
Once mixture has cooled completely, break into rustic pieces. Serve. Store covered at room temperature.
