I have a food processor that is sadly too small to make this — and many other — recipes. Fear not, it is still doable. I will give directions for both techniques.

Makes 55 to 65 1 1/2-inch wafers.
1 1/2 c. all-purpose flour
3/4 c unsweetened cocoa powder
1 c. plus 2 Tb sugar
1/4 tsp salt
1/4 tsp baking soda
14 Tb (1 3/4 sticks) unsalted butter, slightly softened
3 Tb whole milk
1 tsp pure vanilla extract
By hand: Whisk together the flour, cocoa, sugar, salt, and baking soda in a large bowl. Cut butter into about 12 chunks and add them to the bowl. Cut the butter into the dry ingredients with a pastry cutter, two knives or your fingertips until formed into crumbs. Combine the milk and vanilla in a small cup. Add to the bowl and mix thoroughly with a wooden spoon until the mixture begins to form into a ball. Transfer the dough to a large cutting board and knead a few times to make sure it is evenly blended.
In food processor: Combine the flour, cocoa, sugar, salt, and baking soda in the bowl of a food processor and pulse a few times. Cut the butter into about 12 chunks and add them to the bowl. Pulse several times to mix thoroughly. Combine the milk and vanilla in a small cup. With the processor running, add the milk mixture and continue to process until the mixture clumps around the blade or the sides of the bowl. Transfer the dough to a large bowl or a cutting board and knead a few times to make sure it is evenly blended.
Form the dough into two logs each about 8 inches long and 1 1/2 inches in diameter. Wrap the log in wax paper or foil and refrigerate until firm, at least one hour, or until needed.
Position the racks in the upper and lower thirds of the oven and preheat to 350°F. Line the baking sheets with parchment paper. Cut the logs of dough into slices a scant 1/4-inch thick or thinner. (If you slice them as thin as you can to make them extra crispy and delicate, watch the baking time carefully. It will be less.) Place slices one inch apart on the parchment paper to allow room for them to spread. Bake, rotating the baking sheet from top to bottom and back to front about halfway through baking, for a total of 12 to 15 minutes. The cookies will puff up and deflate; they are done about 1 1/2 minutes after they deflate.
Cool the cookies on the baking sheets on racks, or slide the parchment onto racks to cool completely. These cookies may be stored in an airtight container for up to two weeks or be frozen for up to two months.
Note: These cookies should crisp as they cool. If they don’t, you’re not baking them long enough, says Medrich — in which case, return them to the oven to reheat and bake a little longer, then cool again.
Much easier to eat than an entire cake, these cupcake sized treats are perfectly rich and chocolatey. The cream covered wafers soften up into a cake-like consistency when stored in the the refrigerator overnight.
As Deb at Smitten Kitchen says, the wafers are just a little too big for the average cupcake liner. Simply press down the sides a bit and you'll have no trouble. You could make the wafer a little smaller, but either way works just fine. This recipe makes about a dozen cupcakes, but this will vary depending on the size and thickness of your cookies, and the height of your stacks. Five apiece worked well for me.
1 batch of Chocolate Wafers (recipe above)
1 cup whipping cream
1 to 2 spoons of powdered sugar
1/2 teaspoon vanilla
Whip cream with a spoonful or two of powdered sugar and a dash of vanilla or any flavoring of your choice, until the whipped cream holds firm peaks. Spread about two teaspoons whipped cream between each cookie, to the edges, and stack them until you reach the height you’d like. If you spread whipped cream on top of the final cookie, you will end up with a softer lid — a good thing — though a brown cookie on top looks neater.
Set them in the fridge at least overnight or up to a day. The cookies will soften as they set, and become cake-like.
