Why Kefir is a Great Buttermilk Substitute
Both kefir and buttermilk share similar levels of acidity, which is key for activating baking soda and creating those airy bubbles that give cakes their lift. Kefir’s texture is also comparable to buttermilk, ensuring your cake stays beautifully moist. And, bonus! Kefir’s probiotics work wonders, breaking down gluten and resulting in a super tender crumb. You really won’t believe the difference it makes! If you enjoy baking with unique ingredients, you might also like my tips on baking with kefir in general.
Understanding Kefir and its Role in Baking
Kefir might seem a little mysterious, so let’s break down what it is and how it works its magic in our cakes.
What is Kefir?
Kefir is a fermented milk drink, similar to thin yogurt, with a tangy, fizzy flavor. Originating in the Caucasus Mountains, it’s made by adding “kefir grains” (cultures of bacteria and yeast) to milk, fermenting it and providing probiotics for gut health. You can find both milk kefir, which is thicker and resembles buttermilk, and water kefir, a non-dairy option. Milk kefir is perfect for baking—check out my article for other ways to use it, like replacing yogurt in cake recipes! using kefir instead of yogurt in cake.
How Kefir Reacts in Baking
Kefir’s secret weapon in baking is its acidity. See, kefir, just like buttermilk, contains lactic acid. When this lactic acid mixes with baking soda or baking powder (our leavening agents), a chemical reaction happens, creating carbon dioxide gas. Those gas bubbles are what give our cakes their light and airy texture. Kefir behaves almost identically to buttermilk in recipes because of this similar acidity level. It provides that wonderful tangy flavor and helps create a tender crumb, making it a truly excellent substitute. Honestly, my family often can’t even tell the difference!

Baking with Kefir: Tips and Tricks
I’ve learned a few things over the years about baking with kefir. Here are my top tips to ensure your cake turns out perfectly:
Choosing the Right Kefir
Kefir comes in different varieties, like whole milk, low-fat, and even non-dairy. I find whole milk kefir creates a richer, more decadent cake, but low-fat works great if you’re watching your calories. For most cakes, plain kefir is the way to go. Flavored versions can sometimes clash with the other flavors in your recipe, so I stick to plain unless I’m feeling adventurous.

Measuring and Substituting Kefir for Buttermilk
Swapping kefir for buttermilk couldn’t be easier. It’s a simple 1:1 ratio. So, if your recipe calls for 1 cup of buttermilk, you just use 1 cup of this fermented drink. Give it a gentle shake before measuring – this mixes the liquid and thicker parts together. Kefir can sometimes be a bit thicker than buttermilk, so your batter might be a tad thicker too. Don’t worry, this is totally normal! You can find more baking tips and tricks in my article on Southern cornbread.
Adjusting Recipes for Kefir
Kefir has a lovely tang, just like buttermilk, but it can sometimes be a bit more pronounced. If your recipe is really sensitive to tangy flavors, a pinch of extra sugar (maybe a tablespoon or two) can help balance it out. You can also tweak other flavorings. For instance, if you’re making a vanilla cake, a tiny bit more vanilla extract can really enhance the tang. My golden rule? Taste the batter before baking! You’ll thank me later.
Delicious Cake Recipe Using Kefir
This vanilla cake recipe is a family favorite, and it perfectly demonstrates how well kefir works as a buttermilk substitute. My kids gobble it up!
Ingredients
- 2 cups all-purpose flour
- 1 1/2 cups granulated sugar
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup (1 stick) unsalted butter, softened
- 2 large eggs
- 1 cup plain whole milk kefir (give it a good shake!)
- 1 teaspoon vanilla extract
Instructions
- Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan. I like to use parchment paper too, for easy removal.
- In a medium bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
- In a separate large bowl, cream together the softened butter and sugar until light and fluffy. My stand mixer is a lifesaver here! Beat in the eggs one at a time, then stir in the vanilla.
- Gradually add the dry ingredients to the wet ingredients, alternating with the kefir. Start and end with the dry ingredients. Mix until just combined. Don’t overmix – that’s a baking no-no!
- Pour the batter into the prepared pan and spread it out evenly.
- Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
- Let the cake cool in the pan for about 10 minutes before flipping it onto a wire rack to cool completely.

Frequently Asked Questions
Let’s tackle some common questions about kefir and buttermilk substitutes:
What is a good substitute for buttermilk when baking a cake?
No kefir on hand? No problem! Milk with a squeeze of lemon juice or vinegar works wonders. Plain yogurt or sour cream thinned with milk are also good options. Each one has its own little flavor twist, so pick what you like best.
Is it okay to use kefir in baking?
Absolutely! Kefir is a baking superstar. It adds amazing moisture and a subtle tang to cakes, muffins, pancakes – you name it! It’s so similar to buttermilk that often, no one even notices the swap. If you’re interested in learning more about using kefir in baking, take a look at my article specifically on what kefir does in baking.
Are kefir and buttermilk the same?
Nope, not quite. Buttermilk is what’s left over after churning butter. Kefir is a fermented milk drink made with those special kefir grains (cultures of bacteria and yeast). Those cultures give it its probiotic power. They’re different, but they act very similarly in baking.
What can I use if I don’t have buttermilk?
Lots of alternatives! Kefir is my favorite, but you can also mix milk with lemon juice or vinegar. Thinned-out plain yogurt or sour cream works too.
Storage and Serving Suggestions
Let’s keep that cake fresh and delicious!
Storing Your Kefir Cake
An unfrosted cake can hang out at room temperature in an airtight container for up to 3 days. Once it’s frosted, it’s best in the fridge, also in an airtight container, for up to 5 days. Want to keep it longer? Freeze it! Wrap the unfrosted layers really well in plastic wrap and then foil, or use a freezer-safe container. Frozen cake can last for 2-3 months. Just thaw it overnight in the fridge before frosting and serving.
Serving Your Cake
This cake is a crowd-pleaser, plain and simple, or dressed up with toppings. Vanilla ice cream, whipped cream, or fresh berries are all delicious choices. A glass of cold milk or a warm cup of coffee makes the perfect pairing. For a fancy touch, dust the cake with powdered sugar, arrange some fresh fruit on top, or drizzle with a simple glaze.
Conclusion
Using this fermented drink instead of buttermilk is my little secret weapon for a moist, tender, and tangy cake. Plus, it adds a healthy boost thanks to those probiotics. I really hope you give this recipe a try! Don’t stop there – experiment with kefir in other baking recipes. Muffins, pancakes, quick bread – the possibilities are endless!
