Cake: Grease and flour a 15 x 10 x 1-inch (38 cm x 26 cm x 2.54 cm) baking sheet
and line with parchment/spray oil paper. Heat oven to 375 degrees F (190 degrees
Beat egg yolks until thick and lemon-colored. Gradually beat in 1/3 cup (80 mL)
sugar and add vanilla extract.
In another bowl beat egg whites until soft peaks form. Add 1/3 cup (80 mL) sugar
and beat until stiff peaks form. Fold egg yolk mixture into egg white mixture.
Sift dry ingredients and fold into egg mixture. Spread batter into sheet pan
and bake 12 to 15 minutes, until top of cake springs back when touched. Sprinkle
towel with confectioners' sugar. When cake is done, loosen sides and bottom
with spatula and turn out onto towel. While cake is still warm, roll cake and towel
from narrow end. Let cool. Make frosting.
Frosting: Beat shortening and butter till light and fluffy. Beat in sugar. Add
milk, whip till frosting is soft. (Alternately you can use 2 cans of Prepared frosting.)
Assemble: Unroll cake; spread with approximately 1 cup frosting. Sprinkle and
cover with 1 1/2 cups of "M&M's" Chocolate Mini Baking Bits and
re-roll cake. Spread remaining frosting on top and ends of rolled cake and decorate
with remaining "M&M's" Chocolate Mini Baking Bits.
