In a large bowl, beat the milk, nut butter, oil and vanilla until well blended. In a separate bowl, combine 1/4 cup sugar, flour and baking powder. Gradually beat into milk mixture until well blended. Mixture will be thick. Using a spatula, spread/press into a slow cooker coated with cooking spray.
In a medium bowl, combine cocoa and remaining sugar; stir in boiling water. Pour into slow cooker on top of the cake mixture - do NOT stir.
Cover and cook on high until a toothpick inserted in the center comes out clean, about 2 hours. Cake will be cooked in most areas but fudgy in others. Serve warm, with ice cream if desired.
