Step 1

Follow preparation directions on the boxes. Grease 2- 9x13 pans and bake at 325 for 30-35 minutes. Set aside until completely cooled.

Step 2

Place chocolate in a double boiler at a low simmer. Stir chocolate until melted. Turn off the heat and let stand.

Step 3

Beat the cream over ice until it forms soft peaks. OR I put my Kitchen Aid bowl in the freezer for 20 minutes then removed the bowl from the freezer and added the cream and whisked using my Kitchen Aid until it formed soft peaks.

Step 4

Set aside and hold at room temperature.

Step 5

With a mixer, whip egg whites to soft peaks. Gradually add the sugar and continue whipping until firm.

Step 6

Using a whisk, fold in the egg whites all at once to the chocolate.

Step 7

When the whites are almost completely incorporated, fold in the whipped cream.

Step 8

Cover the mousse and refrigerate for approximately 1 hour or until set.

Step 9

Using a mixer whip cream and vanilla until it forms soft peaks, add sugar and whisk until stiff peaks are formed. Chill in the refrigerator until ready to use.

Step 10

Mix brown sugar and cocoa powder in a small bowl. Set aside.

Step 11

In a medium saucepan, cook butter and milk until it starts to bubble (about 5 min on medium heat).

Step 12

Add cocoa mixture. Stirring constantly with a wooden spoon, cook for 2 minutes until smooth.

Step 13

Remove from heat and stir in vanilla.

Step 14

Let sit for at least 5 minutes. It will thicken.

Step 15

Store covered in refrigerator for up to 1 week.

Step 16

Reheat for 10 seconds in microwave before using.

Step 17

Layer the following in a 9x13 serving pan. These usually are just for serving, they allow for higher edges allowing you to add several layers. If you don’t have one I have used a small roasting pan before too or a regular 9x13 but just be careful on not overfilling, may need to omit top brownie layer.

Step 18

Trim off all the edges from the brownies in both 9x13 pans, just 1/4 of an inch and less. This just takes away the crunchy edges you get with brownies.

Step 19

Lay down the first layer in your 9x13 serving pan.

Step 20

Top with all of the dark chocolate mousse.

Step 21

Then add the next layer of brownie gently on top of the mousse.

Step 22

Top with whipped cream.

Step 23

Cover and place in the refrigerator for 1 hour or more until serving.

Step 24

Cut a piece then top with chocolate shaving and drizzle with room temp hot fudge.
