Decadent No-Bake Chocolate Mousse Squares

Chocolate Mousse Squares ~ The summer is rapidly approaching and we will soon be in the midst of many holidays including summer vacations, national holidays, birthdays and barbecues.

For the most part, we still have the regular family and work responsibilities, but also want to take advantage of the fabulous summer weather to host or attend a few random get-togethers with family and friends.

Chocolate Mousse Squares

I have a entertaining secret to share with you!

Next time you’re invited to a potluck, office party or are having friends for a dinner, I have the answer to the “what can I take?” or “what will we have for dessert?” questions.  Well in advance, I make a pan or two of these fabulous, no-bake Chocolate Mousse Squares and have them tucked away in the freezer, ready to impress.

The first time I had these deliciously decadent, Chocolate Mousse Squares was several years ago.  A fellow nurse and I were working the weekend shift in the Operating Room and she brought in a pan of these squares as a little dinnertime treat!

It was love at first bite!  These squares are a silky, smooth, creamy delight; once you have one, you will definitely be hooked.

Today, in advance of the holiday madness,  I am making a batch of these squares.  these are the perfect dessert for both a random potluck or an elegant holiday dinner party!

They are super easy to make and the best part, you can make them days ahead and just store them in your freezer. (NOTE – To avoid encountering the “empty pan phenomenon”,  I suggest storing these squares under tight security!)
