Base layer:
12 chocolate-cream sandwich cookies, crushed
2 tablespoons butter, melted
Main layer:
16 chocolate-cream sandwich cookies
1 1/2 cups malted balls
8 ounces non-dairy whipped topping, thawed OR 3 cups sweetened whipped cream
1 1/2 quarts chocolate ice cream, very slightly softened
Malted Chocolate Sauce (optional, but a very good idea):
1/3 cup unsweetened cocoa powder (natural or Dutch-processed)
1 tablespoon cornstarch
1/3 cup plain malted milk powder
1/4 cup packed brown sugar
1/3 cup milk
1/4 cup corn syrup
1 teaspoon vanilla extract
For the base layer: preheat over to 350 degrees and lightly coat with nonstick cooking spray the bottom of a 9-inch springform pan OR a 9-inch cake pan with the highest sides you can round up. Toss together the 12 crushed cookies and the melted butter and press into the bottom of the prepared pan. Bake for 5 minutes, then cool completely.
For the main layer: break 16 cookies in half and throw them into the work bowl of a food processor, along with your malt balls. Process like crazy (you may have to add in some pulse action) until you have very fine (and highly addictive) malt-flavored cookie crumbs. Reserve about 1/4 cup for garnish. Spread 1/2 of the ice cream evenly over the cooled base layer. Top with 1/2 of the whipped topping or whipped cream. Sprinkle evenly with 1/2 of the malted cookie crumbs. Repeat layers with remaining ice cream, whipped cream/whipped topping, and malted cookie crumbs. Press plastic wrap directly onto the surface of the cake, then wrap the entire pan in foil and freeze several hours at least, or up to several weeks. Cut into wedges to serve, drizzled with hot fudge sauce or plain chocolate sauce or warm Malted Chocolate Sauce and sprinkled with reserved cookie crumbs. Makes approximately 8-10 servings.
For the Malted Chocolate Sauce: in a small saucepan, whisk together the cocoa, cornstarch, malted milk powder, and brown sugar. Add the milk and whisk well, then whisk in the corn syrup. Set the pan over medium heat and stir while bringing it to a full boil. Lower the heat slightly and cook, whisking constantly, about one minute longer, until the sauce thickens and generously coats the back of a spoon. Remove from heat and stir in vanilla. Cool, then refrigerate in a covered jar. Makes about 3/4 cup.
