First of all you are going to need a small square pan. I think they are about 8 or 9 inches square. I bought the one below from Dollar Tree for a pack of 2. I've tried to double the recipe and it doesn't come out quite as well. If you decide to make more than 1 batch, I also recommend not reusing the pan without rinsing out all the chocolate.
3/4 cup flour
1/2 teaspoon baking soda
1/2 teaspoon salt
1/2 cup sugar ( or more if desired, for a sweeter taste)
1/3 cup Crisco shortening
2 tablespoons water
1 (6 ounce) packages chocolate chips
1 teaspoon vanilla
1/2 cup chopped walnuts
1/3-1/2 cup Jack Daniels Whiskey ( or more or less to suit taste)
1 1/2 ounces unsweetened chocolate
1/4 cup unsalted butter
2 cups powdered sugar
3 tablespoons half-and-half
1 tablespoon Jack Daniels Whiskey
1/2 teaspoon vanilla extract
When I make these, I use 1/2 cup. You could easily substitute Jack Daniel's for another liquor, be it a bourbon, whiskey or Bailey's. They would all work perfectly.
Step 1: Spray your baking pan
To get prepped for how quick this is to make, get a separate bowl and place the flour, salt & baking soda.
It is much cheaper to buy whole walnuts and break them up yourself. Prepare this ahead of time as well and place into another bowl.
