Why You Must Make

  • There are 3 luscious layers:  a buttery dark brown sugar crust, a smooth rich, chocolate ganache, and a holiday topping of your choice (I like festive M&Ms, chopped Heath bars, or toasted pecans).
  • They are super easy to make!
  • Changing the colors of the M&Ms makes them perfect for any occasion! 
  • Or you can go half and half with the toppings as I did. I went with  Heath bars to give a double dose of toffee flavor on half of the bars. Being the considerate wife that I am, I sprinkled holiday-colored M & M’s over the other half. As hard as it is to believe, Bill does not like toffee. Crazy man.

Tips for Holiday Baking

  • I know it seems early to be sharing holiday cookie recipes, but if you’re anything like me, the season will creep up on you, and then panic will set in. So go ahead and start collecting recipes early. These bars and all the tasty recipes from my blogger friends are delicious options. My family goes nuts for anything chocolate, so these toffee squares were a hit!
  • Then you’ll just need to set aside an afternoon to bake.
  • Make sure your pantry is stocked with the basics, flour, sugar, brown sugar, vanilla, baking soda, baking powder, and a variety of chocolate.
  • I love to share tins of various cookies and candies with my neighbors at Christmas. Even though I make some old favorites over and over, I’m always on the hunt for new inspiration.
  • PRO-Tip: Did you know you can make dark brown sugar out of regular brown sugar by adding a tablespoon of molasses to the latter? It’s an easy trick when you don’t have dark brown sugar on hand.

Frequently Asked Questions

What is Toffee?

Toffee or Toffy is a candy made by cooking sugar, water (or cream), and often butter to the molten hot temperature of 260-310°. The temperature will vary depending on if a chewy or crisp toffee is desired. It’s often topped with nuts, chocolate, or both.

Why is Toffee So Hard to Make?

The process of candy-making can be daunting. Using an accurate candy thermometer and a good recipe is key since there are a number of ways that toffee can fail. But once you’ve been successful, making toffee will be worth the effort!
The procedure cannot be rushed. With patience, mastering English toffee can be achieved! Making toffee bars is an easy way to get similar flavors without the pressure!

PRO-Tip: To make cutting bars easier, chill thoroughly, then use a sharp knife to score, then cut into squares. These are trickier than some to cut because of the chunks of candy.
