Creating your Snowman Sheet Cake can be a delightful journey! Follow these simple steps to make your cake:

1. Preheat the Oven: Set your oven to 350°F (175°C). Grease and flour a 9×13 inch sheet cake pan.
2. Mix Dry Ingredients: In a large bowl, sift together the flour, granulated sugar, cocoa powder, baking powder, and salt.
3. Combine Wet Ingredients: In another bowl, whisk together the milk, vegetable oil, eggs, and vanilla extract until smooth.
4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, mixing until just combined and no lumps remain.
5. Pour Batter: Pour the batter into the prepared sheet cake pan, spreading it evenly.
6. Bake: Place the pan in the preheated oven and bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.
7. Cool the Cake: Remove from the oven and let the cake cool in the pan for about 30 minutes. Then, transfer it to a wire rack to cool completely.
8. Prepare the Frosting: In a mixing bowl, combine powdered sugar and whipped cream until you achieve a fluffy frosting consistency.
9. Frost the Cake: Once the cake is completely cooled, spread the whipped frosting evenly over the top.
10. Decorate the Snowman: Use candy pieces to design the snowman’s face and buttons. Create the eyes and buttons with black icing, and use orange candy for the carrot nose.
11. Add Final Touches: If desired, sprinkle some coconut flakes around the snowman to mimic snow.
