1 1/2 cups chopped toasted almonds, divided
1 cup packed light brown sugar
1 cup (2 sticks) salted butter
4 bars of chocolate (such as Hershey's Bars)

1. Butter a 7x11-inch pan (or 9x12 for slightly thinner roca). Sprinkle 1 cup of toasted almonds on bottom of the pan.

2. In heavy saucepan at medium-high heat melt butter and add brown sugar. Stir until gently boiling. Reduce heat to medium or medium-low and boil 12 minutes exactly, stirring constantly.

3. Remove the mixture from heat, give it a good stir to mix up that butter and sugar one more time, and immediately pour hot mixture into pan over almonds. (see *Tips below) Place chocolate bars on top. Let them sit a minute or so until melted, then spread chocolate around carefully. Sprinkle with remaining toasted almonds and gently press them into the chocolate..

4. Cool completely, and then break apart into chunks with a sharp knife. Store in a covered container.
