Weight Watchers Recipe of The Day: 2-Ingredient Soda Cake
Dessert doesn't get much easier than this 2-Ingredient Weight Watchers Soda Cake, which turned out better than I expected. It calls for a box of cake mix and club soda or sparkling water.
Weight Watchers 2-Ingredient Club Soda Cake
I first learned of Diet Soda Cake years ago at a Weight Watchers meeting. I've even used the recipe to make delicious guiltless 2-ingredient cupcakes.
But I have to be careful because the artificial sweetener in diet soda can sometimes give me a headache.
So when I heard about using club soda or sparkling water instead of diet soda and thought I'd give it a try.

Weight Watchers 2-Ingredient Soda Cake Recipe Notes
I like to use Betty Crocker cupcake mix when baking cakes. They make one little layer instead of two. (I know from experience when it comes to trying to stay happy, healthy and slim, little cakes are a safer, better bet than big ones, which is why I'm also such a fan of 3-2-1 Microwave mug cake.)
If you can't find the cupcake mix you could always use just half of a regular 2-layer cake mix instead to make 1 small cake. Or use the full cake mix and 12 ounces (1-⅓ cups) of club soda or seltzer to a make 2 small cakes or one large cake in a 9x13-inch pan.
I also added a teaspoon of vanilla for good measure. Then spread the finished cooled cake with the thinnest possible layer of chocolate frosting.
This Weight Watchers club soda cake turned out sweet, moist and fluffy with a tender crumb. We didn't miss the eggs or oil a bit. But without the binding power of eggs, this cake does tend to be a bit crumbly.
I frosted my cake with the thinnest possible layer of chocolate frosting. If you're not a fan of frosting you could sprinkle on a little confectioner's sugar instead and save yourself *2 SmartPoints in the process.

Ingredients for Weight Watchers Soda Cake
Ingredients for 1 Small Cake
- ½ box cake mix
- ⅔ cup of diet soda, soda, club soda, or sparkling water

- 1 box cake mix
- 1 can (12 ounces) diet soda, soda, club soda or sparkling water
How to Make Weight Watchers Soda Cake?
Step 1: Check out the instructions on the box
Follow the directions on the box mix to preheat your oven to the proper temperature. Then, grease a cake pan with cooking spray or line muffin cups with paper liners if you want to make cupcakes.
Step 2: Make the batter
In a large mixing bowl (affiliate link), beat together the cake mix and soda for two minutes, either by hand or with an electric mixer (affiliate link).
Step 3: Bake the cake(s)
Pour the batter into the cake pan(s) or divide the batter evenly among the cupcake cups. Follow the directions on the box mix for cooking times.
Step 4: Decorate
Once the cake is cool, decorate with your favorite frosting or icing. (Or, your favorite canned frosting.) To keep calories and points low, dust with a bit of confectioners sugar. Some Weight Watchers program members like to mix cool whip and sugar free instant pudding for a light and fluffy frosting.

What Flavors Work Best to Make Weight Watchers Soda Cake?
I liked the flavor of plain yellow cake mix and plain club soda. But the options are really endless if you want to get creative with flavor combinations of cake mix and sparkling water or diet soda. The flavor of the soda or sparkling water will be stronger when you use a vanilla or yellow cake. The soda flavor is more subtle in a stronger-flavored cake such as chocolate or spice. Here are a few suggestions to get your creative juices flowing:
- Carrot cake mix + diet ginger ale
- Chocolate cake mix + diet cola
- Chocolate cake mix + diet root beer
- Devil's food cake mix + diet cherry cola
- Lemon cake + lemon-lime sparkling water or soda
- Spice cake + ginger ale or ginger beer
- Strawberry cake mix + berry flavored sparkling water or soda
- Vanilla cake + root beer
- Vanilla cake + orange soda
- Vanilla cake + grape soda

I don't like 'fake' sweeteners either and made a boxed chocolate cake with club soda last year. To make it even better, I added chopped walnuts and instant espresso coffee granules. It was a hit.
🙂
Martha McKinnon
Hi Barbara,
Love the idea of doctoring up the club soda cake with chopped walnuts and instant espresso. Yum 🙂
Barb
Thanks for posting this. I have used the cake w/diet soda in the past. I like the idea of a smaller cake and not using something with artificial sweetener since recently some family members have been getting migraines from them.
Martha McKinnon
You're welcome, Barb! I really think the club soda is a great alternative.
Brenda
I was wondering if you can use regular cake mix and still make two cakes just using 2/3 cup diet soda?Or should I double amount of soda?
Martha McKinnon
Hi Brenda,
If you want to use a whole cake mix to make 2 cakes you will want to double the amount of soda because you are doubling the amount of cake mix. You could also bake all the batter at once in a 9x13-inch pan. Just bake according the the time suggested on the box of cake mix.
Hope this helps.
Tricia
Hi Martha,
Would this work using angel food cake mix?
Thanks
Martha McKinnon
Hi Tricia, I haven't tried it with angel food cake mix. I don't think it would be necessary. I believe
that the Betty Crocker Angel Food Cake Mix only requires that you add water. Hope this helps. ~Martha
Ann
Hi Martha. I was dying for a piece of cake this morning but didn't want to make one from scratch. I remembered one of your posts saying that we can mix cake mix and seltzer. I had a lemon cake mix in the house so I just added 12 ounces of seltzer and a teaspoon of lemon extract. I baked it in a 9 x 13 pan and it's delicious. Thanks so much for sharing this along with all your other recipes.
Martha McKinnon
Hi Ann, So glad you liked it! ~Martha
