Preheat round waffle iron. Spray with no stick cooking spray. Mix all ingredients, except confectioners’ sugar and candy pieces, until blended.
Pour about 1/3 cup of the batter onto center of hot waffle iron. Close lid. Cook about 5 minutes or until no longer steaming. Carefully remove waffle. Repeat with remaining batter.
Break each waffle into 4 triangles. Layer 3 triangles on a serving plate to resemble a Christmas tree. Sprinkle with confectioners’ sugar. Use candy-coated pieces to decorate the tree as ornaments.
