Step 1

Line a 15 1/2 x 10 1/2 jelly roll pan with heavy duty aluminum foil. Spray it generously with nonstick baking spray.

Step 2

Add saltine crackers to foil. I used almost 60 crackers which is a little more than a sleeve.

Step 3

In a small sauce pan, add light brown sugar and butter. Constantly stir mixture over medium-low heat (4 on the knob). Once butter is melted, set a timer and allow mixture to gently boil for 3 minutes. You will want to constantly stir it even when it is gently bubbling.

Step 4

Once mixture turns into thick toffee, spread it over the crackers. Place pan in a 325° Fahrenheit oven and bake for 9 minutes.

Step 5

After toffee is done baking, remove from the oven and place it on top of the stove. Sprinkle on 2 cups of chocolate chips and spread using a rubber spatula.

Step 6

Once chocolate is evenly spread, add 1 cup of white chocolate morsels evenly as well as the M&Ms, and holiday sprinkles.

Step 7

Add entire baking sheet to the freezer and freeze until hardened, about 15 minutes. If you have no room in the freezer, chill in the fridge for about 45 minutes.

Step 8

Once everything is hardened, crack the bars using a knife or your hands.
