Once you start eating matzo toffee, you may not be able to stop! Matzo crackers are topped with buttery caramel, chocolate and slivered almonds and then baked to perfection. —Sharalyn Zander, Jacksonville, Alabama
Line a 15x10x1-in. baking pan with foil; line the foil with parchment. Arrange crackers in pan; set aside.
In a large heavy saucepan over medium heat, melt butter. Stir in brown sugar. Bring to a boil; cook and stir for 3-4 minutes or until sugar is dissolved. Spread evenly over crackers.
Bake at 350° for 15-17 minutes (cover loosely with foil if top browns too quickly). Cool on a wire rack for 5 minutes. Meanwhile, melt chocolate chips and shortening; stir until smooth. Stir in almonds; spread over top. Cool for 1 hour.
Break into pieces. Cover and refrigerate for at least 2 hours or until set. Store in an airtight container.
