Step 1

Preheat the oven at 350°F

Step 2

In a mixing bowl, prepare the cake mix according to the box directions using the ingredients called for on the box- usually water, oil and eggs.

Step 3

Pour the cake batter into a prepared 9x13 baking dish and bake according to the box directions, usually 22-25 minutes of bake time.

Step 4

While the cake is baking, mix 1 tsp peppermint extract into the sweetened condensed milk.

Step 5

When the cake is finished baking poke about 40-50 holes in it using the back of a wooden spoon. Make the holes 2/3 of the way down (not all the way through) and about 1/2-1 inch apart.

Step 6

Evenly pour the sweetened condensed milk over the cake, ensuring the sweetened condensed milk gets into each hole. Place the cake into the fridge for 10-20 minutes to cool.

Step 7

Heat the hot fudge in the microwave 30 seconds-1 minute until the fudge is pourable.

Step 8

Pour the fudge evenly all over the cake on top of the sweetened condensed milk layer. Spread the fudge over the cake so it's an even layer. Let the cake cool completely either in the fridge or on the countertop until the fudge is set.

Step 9

When the cake is cool, mix 1/2 tsp peppermint extract with the cool whip and spread evenly over the cake.

Step 10

Garnish the top with mini chocolate chips or shaved chocolate and crushed candy canes.

Step 11

Cut into slices and enjoy!
