Lemon Surprise Cake

Why did I call this a lemon “surprise” cake? Because it has lemon-lime soda as an ingredient! I was a bit shocked that one little can of soda can make such a wonderful difference in a cake, but it did. I can’t wait to try this with other flavors!

Traditionally speaking, this is a lemon pound cake and has been around for many generations. Our grandmothers were masters of finding ways to save money and use what they had to create beautiful and delicious desserts.

What is a Lemon Surprise Cake? 

This is actually considered a pound cake. The definition of pound cake is this: a rich cake containing a pound, or equal weights, of each chief ingredient, typically flour, butter, and sugar.  One of the original lemon pound cake recipes was: (OH MY GOSH A DOZEN EGGS?!?!) 

  • 1 pound sugar
  • 1 pound butter
  • 1 pound flour
  • 1 dozen eggs
  • 1/4 cup lemon juice
  • 1 tablespoon lemon zest

With changes in the sourcing of flours, accessibility of ingredients, quality of butter, and the addition of extracts in baking, some modifications have been made to that original recipe.

So if you want to get technical, this lemon pound cake recipe does not have equal parts of flour, butter, and sugar. However, it still maintains the rich flavor and beautiful, dense crumb that is commonly associated with a pound cake.

  1. Putting soda and cake it’s not that unusual I have a friend that has a recipe for a mayonnaise cake that is absolutely delicious and by the way it is chocolate and it has cream cheese frosting this combo makes the whole thing scrumptious.

  2. I made this recipe yesterday and it was a huge hit! I will definitely be making this again! Thank you for all of the wonderful recipes!

  3. Baked it.. an easy delicious summertime option. Be advised not to rush getting it out of the pan… I thought I oiled it snd floured it enough but it did stick… next time I will let it cool longer. I managed well having to taste test the broken part😜

  4. Could use fresh lemon juice and lemon zest instead of lemon extract? Cuz the extract taste kinda nasty to me!

  5. Horrible recipe. The icing directions are awful. I followed them as directed and I’m left with confection sugar mixed (still in powdered form)with butter not a glaze.
