Easy 2-Ingredient Lemon Cake (2024)

This 2-ingredient lemon cake has the perfect balance of sweet and tart. It’s also super easy to make and takes very little time.

Lemon Cake or Lemon Bars?

Since I’d never made this before, I had no idea how it would turn out. But I’m always up for an adventure in the kitchen.

In other words, I’m not afraid to fail—something I’ve done a time or two …or more.

I’ll go ahead and give you a hint. This lemon cake was a delicious success!

Now back to the cake.

I started out experimenting with the ingredients listed below and thought it would have more of a regular cake-like texture. However, it’s different and gives you a chewier bite—sort of like dessert bars.

So I had a difficult time deciding whether I should call this cake or lemon bars. Regardless of what it’s called, though, my husband and I both agree that it is absolutely delicious.

I’ve made other 2-ingredient cakes, and they’re all delicious! Not surprisingly, this apple cake has been one of the most popular. It’s super easy to make and packed with flavor.

Another delicious and easy dessert that is a showstopper is this 2-ingredient cherry chocolate cake. It’s rich and decadent, making it perfect for special occasions.

My personal favorite is this 2-ingredient peach cake since I like anything with peaches. Like the other 2-ingredient cakes, you can top it with whatever you want.

2-Ingredient Lemon Cake Ingredients

As the name implies, there are two ingredients for this dessert—lemon cake mix and a lemon-lime carbonated drink. You can use Sprite, 7-Up, or any generic drink. It doesn’t matter.

I have to use a gluten-free cake mix. However, you can use a regular one, and it will turn out the same.

Granted, the cake mix is one of the ingredients, and it takes the place of a lot of items. So I suppose you can technically say it has more than two ingredients.

But I’m still calling the cake mix an ingredient … just one ingredient. And the drink is the other.

You don’t have to add frosting or any kind of topping. But I chose to ice this with store-bought vanilla frosting and lemon zest.

How to Make 2-Ingredient Lemon Cake

This is so easy anyone can do it. All you have to do is combine the cake mix with the lemon-lime drink.

I highly recommend using a large mixing bowl because the mixture will fizz up. You don’t want it overflowing as you stir.

Since these drinks come in so many different sizes, please check the label against the printable recipe card at the bottom. That’s so you don’t use too much or too little.

After you mix the two ingredients, pour them into a 13” x 9” greased baking pan. I use nonstick cooking spray.

Bake for 30 minutes in a 350-degree oven. Then remove it and allow it to cool before adding any topping.

I like the topping I chose, but there are other things you can use. I almost used cream cheese frosting but changed my mind because I wanted the lemon flavor to stand out.

If you have whipped topping, you can cover the entire cake with it. Or you can put whipped cream on each bar as you serve it.

I also added some lemon zest. After all, lemon is good, so more lemon must be better, right?

We were very happy with how this turned out. I planned to freeze half of the cake, but we keep nibbling.

So I doubt if there will be any left in a few days. Oops!
