Rocky Road Snack cake
3/4 cup all-purpose flour
1/4 cup soy flour
3/4 cup unsweetened cocoa
3/4 teaspoon baking powder
1/2 teaspoon salt
1 1/4 cups sugar
1 cup cubed reduced-fat firm tofu (about 6 ounces)
1/2 cup vanilla-flavored low-fat soy milk
1/4 cup butter, softened
1 cup miniature marshmallows, divided
1/3 cup chopped walnuts, divided
Cooking spray

Preheat oven to 375°.
Lightly spoon flours into dry measuring cups, and level with a knife. Combine flours, cocoa, baking powder, and salt in a large bowl.

Combine sugar, tofu, soy milk, and butter in a food processor or blender, and process until smooth. Add to flour mixture, stirring just until moist. Stir in 2/3 cup marshmallows and 1/4 cup walnuts.

Spread the batter into a 9-inch square baking pan coated with cooking spray. Sprinkle with the remaining marshmallows and walnuts. Bake at 375° for 25 minutes or until a wooden pick inserted in center comes out clean. Cool in pan on a wire rack 5 minutes. Cut into squares.
