On a silicone baking mat, place matzo sheets side by side in a square pattern. Set aside.
In a medium saucepan over high heat, combine sugar, water, and butter. Cook until mixture registers 355° on a candy thermometer. Carefully pour mixture over matzo, spreading with a spatula to cover. Allow toffee mixture to cool and harden, approximately 10 minutes.
Meanwhile, place chocolate in a microwave-safe bowl, and microwave on high in 30-second intervals, stirring well between each interval, until melted, 1 to 1½ minutes total. Spread chocolate mixture over toffee mixture. Sprinkle evenly with almonds.
Allow mixture to cool and harden at room temperature for 2½ hours. Break brittle into bite-size pieces. Note: Brittle can be stored in an airtight container in a cool place for up to 3 days.
