Okay so I’ve been testing out some wild ‘minimal ingredient’ recipes lately and stumbled upon this 2-ingredient strawberry cake. And let me tell you, it’s legit. Like, shockingly good for how ridiculously simple it is. I’ve made it three times this week already. If you think baking is hard or you’re always short on time, this is your jam. Seriously, just two things from the grocery store and you’re basically a baker.

What You Actually Need (No, Really, Just Two Things)
This is the part where you might think I’m kidding, but I’m not. You need one box of strawberry cake mix – I usually grab Duncan Hines from Walmart because it’s like $1.50. The other ingredient? Carbonated water. Yep. Plain seltzer water works best. I’ve tried sparkling cider once and it was… interesting, but plain seltzer is the way to go for a pure strawberry flavor. You’re looking at less than $3 total if you don’t have seltzer already. That’s insane value. This whole recipe is a total win for a lazy Tuesday night.

The Cake Mix Choice Matters
Stick with a classic strawberry cake mix. Avoid ones with pudding in the mix or super fancy flavors. The goal here is simplicity and letting that strawberry flavor shine. Duncan Hines or Betty Crocker are usually reliable for consistent results.
Mixing It Up: The ‘No Mess, No Stress’ Method
Alright, here’s the deal. You dump the entire box of cake mix into a bowl. Then, you start adding the seltzer water. This is the crucial part: you don’t add all the liquid at once. You add it gradually, mixing as you go. The box usually calls for like 1 cup of water, but with seltzer, you’ll probably need less. Aim for a thick batter, like the consistency of pancake batter. Too thin and it’ll be dense and weird. Too thick and it won’t bake properly. It’s a little bit of an art, but you’ll get it. It takes like 5 minutes, tops.
Seltzer vs. Other Liquids
Carbonation is key here. The bubbles in the seltzer help create a lighter, fluffier cake texture without any eggs or oil. Don’t use flat water or milk; it just won’t work the same way.
Baking This Magical Two-Ingredient Wonder
Preheat your oven to 350°F (175°C). Grease and flour a standard 8×8 inch baking pan or a 9-inch round pan. Pour your batter in. Now, the baking time. This is where it varies a bit because of the seltzer. It usually takes between 25-35 minutes. You gotta check it with a toothpick. If it comes out clean, you’re golden. If there’s wet batter, give it a few more minutes. Mine usually takes about 30 minutes. Don’t overbake it, or it’ll get dry real fast. Seriously, set a timer and check early.
Pan Prep is Non-Negotiable
Even though there’s no oil or eggs, you still need to properly grease and flour your pan. Trust me, you don’t want this sticking. A quick spray of baking spray and a dusting of flour is all you need.
Serving Suggestions: Keep It Simple, Silly!
This cake is honestly delicious on its own. Warm, slightly sweet, with that hint of strawberry. But if you want to get fancy (and who doesn’t sometimes?), a dusting of powdered sugar is classic. Or, and this is my favorite, a dollop of whipped cream and some fresh strawberries from Trader Joe’s (they have the best ones in May!). You could even do a simple glaze with powdered sugar and a splash of milk. It’s so forgiving, you can really do whatever you want. Or just eat it straight from the pan, I won’t tell.
Frosting Fanatics Rejoice
You can totally use a store-bought frosting if you want. A vanilla or cream cheese frosting pairs really well. Just make sure the cake is completely cool first, otherwise, you’ll have a melty mess.
⭐ Pro Tips
- Use Diamond Crystal kosher salt for better flavor control in any frosting you make (if you go that route).
- Buy store-brand seltzer water from a place like Costco or Sam’s Club if you make this often; it’s way cheaper in bulk.
- Beginners often add too much seltzer, resulting in a gummy cake. Start with less and add more only if needed.
