This recipe brings me back to my childhood. Around Christmas time, my mom would always break out about 100 different cookie recipes, and toffee square bars were my absolute favorite.
When we lived in Wisconsin and Michigan, my mom would pack up the completed squares in tins and leave them on the shelf in the garage. Since it was always the middle of winter when she made them, keeping the squares in the garage essentially kept them refrigerated! Even though they don’t need to be stored in the fridge, to this day I still like to keep them cold. Ah, nostalgia…and deliciousness…
- 1½ cups butter, room temperature
- 1½ cups brown sugar, packed
- 2 egg yolks
- 1 tsp vanilla
- 3 cups flour
- 1 bag chocolate chips
- chopped walnuts (optional)
- Preheat oven to 400 degrees F.
- With a mixer, cream butter and brown sugar over medium speed. Slowly add egg and vanilla.
- Gradually add flour to mix on medium-low speed. Batter should be thick/stiff.
- Spread batter evenly in 9x13 inch pan.
- Bake for 20 minutes, or until a light golden brown.
- Remove bars from oven and sprinkle the bag of chocolate chips evenly over the top. Place pan back in the oven for 2 minutes to melt the chocolate.
- Remove pan from oven and spread the melted chocolate evenly across the bars. If desired, add chopped walnut pieces. Let cool completely.
- Using a sharp knife, cut bars into squares.
