Tips & Substitutions
For a richer chocolate flavor, consider using dark cocoa powder instead of regular cocoa. If you don’t have buttermilk, you can substitute it with milk mixed with a tablespoon of vinegar or lemon juice. Ensure your margarine and shortening are at room temperature before melting for a smoother batter. Mixing in some chocolate chips can add extra texture and flavor.
Serving Suggestions

Frequently Asked Questions
Can I use a different type of flour for this recipe?
Yes, you can substitute all-purpose flour with cake flour for a lighter texture, or use whole wheat flour for a healthier option. Keep in mind that using whole wheat may change the flavor slightly, so adjust the sugar if necessary.
What can I do if I don’t have vegetable shortening?
If you don’t have vegetable shortening, you can replace it with an equal amount of unsalted butter or coconut oil. This will slightly alter the flavor and texture, but it will still yield a delicious cake.
How can I make this cake gluten-free?
To make this chocolate sheet cake gluten-free, simply replace the all-purpose flour with a gluten-free flour blend. Make sure the blend contains xanthan gum, or add it separately according to the package instructions to help bind the ingredients.
