Adapted from Valya's Taste of Home - No Bake Graham Cracker Cake.
This recipe comes from a friend and it is simply the best cake in regards to taste and easy of preparation. Only three ingredients needed. This is a no bake / ice box type of cake which needs time in the fridge to soften up. I made this by cutting the recipe listed here in half and the photos will reflect that.
Add the whipping cream to a large mixing bowl, beat with an electric mixer until the cream thickens.
Add the sour cream and beat that in until mixed in, scraping down the sides of the bowl so it is all incorporated.
Spread some of the cream mixture on a plate or cake tray, I used a rubber spatula, and place the first layer of crackers to set them in place to make the base of the cake. (I cut the recipe in half and only used 3 crackers wide to make the base, if using the full recipe, you will want to use two rows of 4 crackers each to make a square.)
Spread some cream mixture on top of the base crackers about twice the thickness of a cracker and place more crackers on top, pressing them into place. Repeat this process making the cake as tall as you like. (I made mine with 8 layers of crackers.)
Now spread another layer on the top and clean up the sides using more cream mixture as needed to cover the cake.
For decoration, crush 2-3 crackers in a zip lock bag with a rolling pin and sprinkle the top and sides with the crumbs. Cover and place the cake in the fridge for at least 4 hours, this is to soften the crackers. Or use a variant as I did and I used colored sprinkles on the top.
To cut this cake, and these instructions come from the author of this recipe and it is highly advised to follow this or you will have a crumbly sticky mess. Fill a tall glass with hot water and place a long knife in it to get warm. Remove the knife from the water, wipe dry with a paper towel and make one downward cut and remove the knife, wipe with a paper towel and place back in the water to warm, repeat that process to cut all the servings. Serve and enjoy!
Notes
Variant: 1. Use sprinkles as desired for decoration in place of the crushed graham crackers. 2. Use cinnamon graham crackers or chocolate graham crackers in place of honey graham crackers.
