Mudslide cookies get their name because the dough is very soft, almost like cake dough, very gooey and messy. They are yum-yum-yum!
Makes 24 large cookies
Flourless cooking spray for greasing
3/4 cup flour
1 Tbsp baking powder
1/8 tsp salt
1 Tbsp powder instant Postum (or coffee)*
1 Tbsp boiling water
1 tsp vanilla extract
7 oz unsweetened chocolate, coarsely chopped
6 oz bittersweet chocolate, coarsely chopped
8 Tbsp (1 stick) unsalted butter
7 large eggs
2 3/4 cup sugar
2 cups chopped walnuts
1 1/2 cups bittersweet chocolate chips
Preheat the oven to 350 F. Lightly spray cookie sheets with cooking spray or line with parchment paper.
Sift the flour, baking powder and salt into a bowl and set aside.
Combine the Postum and boiling water to make a paste. Blend in the vanilla extract, set aside.
Melt the chopped unsweetened chocolate, chopped bittersweet chocolate, and the butter in a double boiler over low heat or in a bowl in the microwave in 15-to 20- second intervals. Gently stir to blend.
In a stand mixer fitted with the whisk attachment, beat together the eggs, sugar, and Postum* paste mixture on high speed until light in texture and thick, 6-8 minutes. Add the chocolate mixture with the machine running on medium speed. On low speed, mix in the dry ingredients until just blended. Mix in the walnuts and chocolate chips until blended. Scrape down the bowl as needed during mixing to blend evenly.
Using a 1/4-cup measure as a scoop, fill it with dough, level it, and drop the dough onto a prepared cookie sheet, leaving 3-4 inches between the cookies.
Bake the cookies until they are cracked on top but still slightly moist, rotating the pans as necessary to bake the cookies evenly, 14 minutes. Allow the cookies to cool slightly on the baking sheet before transferring them to a wire racks to cool completely.
*In the original recipe instant coffee was used, but I don't drink coffee, so I don't have it around the house. I have used instant Postum instead of coffee in the past and it worked perfect for this recipe, the hard part is that it is no longer available; I think I bought the last jar available. I found a sight that also recommended Teeccino Caffeine-free herbal coffee, which is basically the same as Postum and it is still in stores! I am going to try cocoa power and see how that works.
