It’s a “let’s have a big slice of cake” kinda day. Don’t you think?

Honestly, for me, it is. Because, truth time- – I had a slice for breakfast. I don’t normally do that, but, gosh, this cake is really yummy and I couldn’t resist sneaking a slice. 🤭

Ingredients Needed

  • Yellow cake mix
  • Eggs
  • Milk
  • Olive oil
  • Vanilla
  • Additional for frosting: Unsweetened cocoa powder, butter, milk & powdered sugar

Ingredients Notes

Do I Have to Use Olive Oil?

Nope. If you don’t want to use it, feel free to replace it with the same amount of melted butter or a neutral tasting oil ( ex: vegetable, sunflower, canola, etc)

No Powdered Sugar on Hand?

Make it homemade!

Recipe Notes

  • If you don’t want to make a 9 x 13 sheet cake, this batter can also make a layer cake or 24 cupcakes. See the notes in the recipe card for baking times.
  • Depending on what size cake you make, you may have leftover frosting. If that happens, store it in the refrigerator in a covered container. It will be good for about a week.
