Cathedral Glass Dessert: The WannaBe SuperHeroMom's Modified Edition

Anything made with Mini Marshmallows in the ingredients is a have to have dessert in this house.
To that yummy delicious Butterscotch stuff,to Ambrosia, to OoeyGooey Smores; and everything in between it isn't dessert without Marshmallows.. The best is when you have Peeps candy to chop up and substitute for the Marshmallows , but sadly have none at this moment. Okay so Peeps don't last long enough round here either.
I had completely forgotten about Cathedral Glass , until I saw a picture of it on Social Media. The memory of how amazing this dessert was came flooding back with the taste memory exploding on my taste bud  that I had to make it .
It is seriously no secret around here that sugar is a way of life in this household so this recipe is sweet and I mean SWEET, but oh my goodness so yummy.

Recipe
1 C. Soft butter( I used Mirage Margarine)
1C. Packed and I mean packed Brown Sugar
2 Eggs
2 C. Flour
1/2 tsp salt
1 Tbsp Cocoa powder
2Tbsp Sugar
1/2 bag of semi sweet Chocolate Chips
1/2 C. Butter( I used Mirage Margarine)
2 C. White Sugar
2 Eggs Beaten
1/2 bag of Colored Marshmallows ( I would have used a whole bag , only we had already eaten half the bag as treats)
1 C unsweetened Coconut

Heat oven to 350'
Mix 1 cup butter, the brown sugar, 2 eggs mix well, add in cocao and 2 tbsp of sugar..then add in flour and salt. Press into a greased pan , at least a 9 in one. I used my round . Bake for about 25-30 min. Bring out and let it cool while you prepare the rest.
Melt the 1/2 cup of butter and the chocolate chips over med. heat in a large sauce pan. Once melted add white sugar and 2 beaten eggs . Beat until smooth then slowly bring to just a boil to cook the eggs. Stir very often so that it doesn't burn.  Immediately once the bubbles start remove from heat and add the marshmallows and coconut . Stir till incorporated, then move to top of cake base and spread evenly. Place in fridge.
The only crappy part is the wait time, you have to let it set at least 3 hours in the fridge before you can cut it into squares.

So as you can tell from the dripping chocolate in this first photo , I couldn't wait the full 3 hours .

So delicious and so sweet. Would be more fun sharing with others instead of just me and my little one ,but hey more for us .
Enjoy!!!
