Ingredients

  • Canola Oil: I use organic canola oil because it's the most neutral oil. But, if you are avoiding seed oils, use olive oil or avocado oil.
  • Buttermilk: You can use store bought or you can also make your own with my Organic Buttermilk Recipe.
  • Cake Flour: I use my Homemade Organic Cake Flour, but store bought also works.
  • Vanilla Bean: I use Lafaza Organic Ground Vanilla Bean for a really good depth of flavor that's much different than just vanilla extract. But, you can use vanilla extract if you prefer.
  • Vanilla Extract: I use Simply Organic Vanilla Extract in the frosting.
  • Sprinkles: I use India Tree Nature’s Colors White Sprinkles for naturally colored sprinkles. These are totally optional.

Baker's Tips for Vanilla Buttermilk Sheet Cake with Vanilla Frosting

  • Always use a scale for the best results.
  • You can use a hand mixer or stand mixer for this recipe, whatever you prefer.
  • If you're using a hand mixer for the batter, you should add in the flour in thirds. This will ensure that it doesn't fly everywhere!
  • You can use canola oil or extra virgin olive oil. I've tested this with both! Olive oil will make this cake seed oil free, if you also remove the sprinkles.
  • Gluten Free — Replace the cake flour with 425 grams (heaping 2 ⅔ cups) gluten free flour blend.
  • Be sure to store this cake in an airtight container in the fridge because the icing has heavy whipping cream.

Recipe FAQ's

What if I don't have buttermilk?

If you don’t have buttermilk you can easily make your own at home with two simple ingredients – milk and a lemon! Try my Organic Buttermilk Recipe recipe. But, if you don’t have a lemon, you can always just use regular milk in its place, it just won’t have that signature buttermilk flavor but it will still make a delicious simple vanilla sheet cake recipe!

Can I make this sheet cake ahead of time?

Yes, if you need to make this Vanilla Buttermilk Sheet Sheet Cake in advance, you can do that. I would recommend making the cake and leaving it in the pan and frosting it in the pan. The pan combined with the icing on top (so long as you go to the edges) will help seal the cake in and it won’t dry out. Store it in the fridge and then pull it out about 30 minutes before serving.

How do you store sheet cake?

Cakes are moist and fluffy, so storing them in an airtight container is best. If you have a cake dome, that also is the best way to store them! Because the icing has heavy whipping cream, make sure to store in the fridge.
