it's extremely simple to make & is great for gift-giving. photo below in case you need 'em.
saltines (I use the generic version)
2 sticks butter
1 cup light brown sugar
a bag chocolate chips (I use semi-sweet)
crushed nuts (I like pecans or walnuts)
preheat oven to 350
melt butter & sugar on low in a small pot on the stove until completely blended.
cover a raised-edged cookie sheet with aluminum foil (I used a silpat mat instead).
completely line the cookie sheet with saltine crackers.
pour blended butter & sugar mixture over crackers.
bake at 350 degrees for 7 minutes.
remove from oven. sprinkle chocolate chips over toffee.
put back in the oven for 2 minutes to help melt the chocolate.
remove from the oven & carefully spread the melted chocolate chips with a spatula.
sprinkle some chopped nuts over the toffee.
let cool & then put in refrigerator until hard (do not freeze).
once toffee is hard, remove from foil & break apart.
store in an airtight container in the fridge. I promise it won't last that long, though.
