1. Preheat oven to 350°F. Spray Stoneware Fluted Pan with vegetable oil. For cake, place cake mix in Classic Batter Bowl. In Small Batter Bowl, whisk water, peanut butter and eggs until well blended. Stir peanut butter mixture into cake mix. Mix 2 minutes or until well blended.
2. Pour half of batter (about 2 cups) into prepared pan. Melt chocolate in Small Micro-Cooker® on HIGH 1 minute, stirring every 15 seconds or until melted and smooth. Stir into remaining batter. Using Small Scoop, drop chocolate batter onto batter in pan; swirl with Skinny Scraper. Bake 50-55 minutes or until Cake Tester inserted near center of cake comes out clean. Cool 15 minutes in pan. Carefully invert pan onto Stackable Cooling Rack to remove cake. Cool 30 minutes.
3. For glaze, whisk peanut butter and 2 tablespoons milk until smooth. Add powdered sugar; mix until smooth. If necessary, gradually add additional 1 tablespoon milk until glaze is of desired consistency. Drizzle glaze over cake; sprinkle nuts evenly over cake.
