Chocolate Swirl Zucchini Sheet Cake Recipes

Steps:

• Preheat oven to 350 degrees F (175 degrees C). Spray a sheet cake pan with cooking spray. Sift together the flour, cocoa powder, baking soda, and salt.
• In a mixing bowl, beat together 3 cups of sugar with canola oil with an electric mixer on low speed until the mixture is smooth; add 3 eggs one at a time, and beat again to combine. Beat in zucchini and vanilla until well combined. Beat the flour mixture into the sugar mixture by fourths, alternating with 1/4 cup of buttermilk after every portion of flour mixture. Mix the batter for 1 minute on medium-high speed, and pour the batter into the prepared baking pan.
• In a bowl, mix together the cream cheese and 1/4 cup of sugar until thoroughly combined, then mix in 1 egg until the cream cheese mixture is smooth. Spoon dollops of the cream cheese here and there over the cake batter, and swirl the cream cheese mixture through the batter with a table knife to make a marbled effect. Sprinkle the milk chocolate and semisweet chocolate chips over the cake.
• Bake in the preheated oven until a toothpick inserted into the chocolate portion of the center of the cake comes out with moist crumbs, 25 to 30 minutes. Cool on a rack.

Steps:

• In a large bowl, combine sugar and oil. Add eggs, one at a time, beating well after each addition. Combine flour, cocoa, baking soda, baking powder and salt; gradually add to the egg mixture alternately with the milk. Stir in the zucchini and extract. Pour into a greased 15x10x1-in. baking pan. Bake at 375° for 25 minutes or until cake tests done. While cake is baking, combine all frosting ingredients. Mix until smooth. Spread frosting over cake while hot. Cool on wire rack.

Steps:

• Cake: Preheat oven to 350 degrees. Butter a 10-by-15-inch jelly-roll pan. Line bottom with parchment, leaving a 2-inch overhang on 2 sides; butter parchment.
• Whisk together flour, cocoa, granulated sugar, baking powder, baking soda, and salt. In another bowl, whisk together eggs, butter, and vanilla. Stir egg mixture into flour mixture until batter loosens, about 1 minute. Stir in zucchini and chocolate (batter will be quite thick). Spread evenly into prepared pan; smooth top with a spatula. Bake until a tester inserted into cake comes out clean, 28 to 30 minutes. Transfer to a wire rack; let cool completely. Remove from pan.
• Frosting: Beat butter on medium-high speed until smooth, 2 minutes. Add cream cheese; beat to combine. Reduce speed to medium-low and add confectioners' sugar, 1/2 cup at a time, beating until thickened. Beat in vanilla. Spread frosting over cake, scatter with zucchini blossoms, and serve. Cake can be refrigerated (without blossoms) up to 8 hours.

Steps:

• Cream butter and sugar together until light and fluffy.
• Add eggs, beating in one at a time.
• Sift over flour and baking powder and fold into butter mixture.
• Divide the mixture in half. Place one half in a separate bowl and mix in vanilla. Sift cocoa over other half of mixture and fold inches.
• Place alternate tablespoon of mixture into a baking paper-lined 20cm cake tin.
• Swirl the mixtures together with wooden skewer.
• Bake at 180 C for 35 - 40 minutes or until cake springs back when lightly touched.
• Cool cake a little. Turn out onto a cake rack and ice when cold.
• Icing: Melt butter and chocolate over a low heat, stir in icing sugar.
• Add water and mix to combine. Spread over cake when cool.
• If you wish to decorate the cake, use a potato peeler and peel white chocolate into curls and sprinkle over icing.
