All Cake Recipe: One-Bowl Wonder With Foolproof Moisture

This one-bowl all cake recipe delivers restaurant-quality moisture without the fuss of multiple mixing steps or layering. 💛 The secret lies in a simple buttermilk substitute (vinegar + milk) that tenderizes the crumb, while vegetable oil keeps it velvety for days. I've baked this version over 50 times—it never fails to impress, even with beginners.

The magic happens in the mixing: creaming butter and sugar properly creates air pockets, while the single bowl method ensures no dry spots. No special tools required—just a standard 9x13-inch pan and 350°F oven. The recipe accommodates chocolate, vanilla, or spice variations with just a few ingredient swaps, making it versatile for any occasion.

What you'll end up with is a cake that's perfectly moist in the center, golden on top, and holds its shape beautifully. The texture stays tender for 5-7 days when stored properly, and it freezes exceptionally well for last-minute celebrations. This is the kind of cake that makes you look like a pro.

Whether you're celebrating a birthday, holiday, or just craving dessert, this foolproof method delivers consistent results every time. Let's get baking!

Ingredients for all cake

Twelve essential ingredients transform into the perfect cake with foolproof moisture every time.

The foundation of this recipe lies in its ingredient quality. Diamond Crystal baking powder is preferred for its reliable lift, though Aluminum-free brands work equally well. For the butter, European-style unsalted creates a richer crumb, but any brand will suffice if melted properly. The eggs should be at room temperature to blend seamlessly with the melted butter—cold eggs can create lumps. Whole milk adds moisture and richness, though 2% works in a pinch. For the flour, King Arthur or Gold Medal brands are ideal due to their consistent protein content, which ensures reliable gluten development without overworking the batter.

No vanilla extract? Vanilla bean paste works beautifully, though you'll need about half the amount. Short on cocoa powder? Melted dark chocolate (6 oz) can replace it in chocolate variations. The white vinegar might seem unusual, but it tenderizes the gluten for a lighter crumb—lemon juice works too at the same quantity. For spice variations, pumpkin pie spice (1 tsp) adds warmth without altering the recipe's integrity. The vegetable oil can be swapped for melted coconut oil for a dairy-free adaptation, though texture may vary slightly. All ingredients should be measured precisely using the spoon-and-level method for accurate results.

This batter should be used immediately after mixing to ensure optimal texture. For storage, cover the bowl with plastic wrap and refrigerate for up to 24 hours—though freshly mixed batter yields the best results. The cake itself keeps well at room temperature for 3 days wrapped in foil, or up to 5 days refrigerated. For longer storage, slice and freeze portions for up to 3 months. Reheat slices in a 250°F oven for 5 minutes to restore moisture. The recipe scales perfectly for larger batches—simply double all ingredients and bake in a 9x13-inch pan instead of the standard 8-inch round.

Step-by-step instructions for one-bowl all cake

This method delivers consistently moist, tender cake with minimal effort—no mixing bowls to wash.

In a large mixing bowl, combine the 2.5 cups all-purpose flour, 2 tsp baking powder, 0.5 tsp salt, 0.5 cup cocoa powder, and 1 tsp ground cinnamon. Whisk these dry ingredients together until fully incorporated—this ensures even distribution and prevents pockets of dry flour in your cake. Sift the flour first if you have time, but whisking works fine for this one-bowl approach.

In a separate bowl, whisk together the 1 cup milk, 1 tbsp white vinegar, and 0.25 cup vegetable oil. Let this mixture sit for 5 minutes—you'll see it thicken slightly as the vinegar curdles the milk. This creates a tenderizing effect that keeps your cake moist for days. The oil also adds richness that butter alone can't match in this recipe.

Add the 1 cup melted unsalted butter (cooled to 100°F) and 2 cups granulated sugar to the dry ingredients. Mix on low speed with an electric mixer for 30 seconds until the sugar begins to dissolve. The butter should be slightly cooled to prevent scrambling the eggs later—if it's too hot, the eggs will cook immediately rather than emulsify properly.

With the mixer running on low, add the 3 whole large eggs one at a time, allowing each to incorporate fully before adding the next. Scrape down the sides of the bowl with a rubber spatula to ensure even mixing. Then add the milk mixture and 2 tsp vanilla extract. Mix on medium speed for 1 minute until just combined—overmixing develops gluten and makes the cake tough.

Preheat your oven to 350°F and grease two 9-inch round cake pans (or one 9x13-inch pan) thoroughly with butter or baking spray. Divide the batter evenly between the prepared pans. Tap each pan firmly on the counter 3-4 times to remove any air bubbles that might cause uneven rising.

Bake for 25-30 minutes until a toothpick inserted in the center comes out clean. The edges should be golden brown while the top remains slightly springy to the touch. Rotate the pans halfway through baking if your oven has hot spots. For extra moisture, place the pans on a baking sheet lined with parchment paper to catch any drips.

Remove the cakes from the oven and let them cool in their pans for 10 minutes. Then transfer to a wire rack to cool completely. The key to maintaining moisture is to serve the cake at room temperature—this allows the internal structure to set properly while keeping the crumb tender. For best results, store any leftovers in an airtight container with a slice of bread to absorb excess moisture.

This cake stays wonderfully moist for up to 3 days at room temperature or 1 week refrigerated. The combination of vinegar, oil, and proper cooling technique creates that signature tender crumb that makes this recipe legendary. Cut into generous slices—this is one cake that shines when served thick.

Essential equipment for all cake

Mixing Essentials

Your stand mixer or hand mixer is non-negotiable for this recipe—I use my KitchenAid Artisan Series for its consistent torque. The flat beater attachment works best for combining ingredients without overmixing. For budget-friendly options, a hand mixer like the Black+Decker BM4500 handles the job just as well when used at medium speed. 🔥

Measuring Tools

Precision matters here, so invest in a stainless steel measuring cups set (I recommend OXO Good Grips) for dry ingredients and a liquid measuring pitcher with clear markings. For the vegetable oil and melted butter, a medicine dropper ensures exact measurements—especially important for that tenderizing effect from the oil. A digital kitchen scale (like Escali Primo) is ideal for weighing butter and flour if you prefer metric accuracy.

Baking Pans

Two 9-inch round cake pans are standard, but I also love using Wilton Perfect Results pans—they're nonstick and release cakes beautifully. For a sheet cake variation, a 9x13-inch half-sheet pan works perfectly. Always grease pans with butter or baking spray (I prefer Baker's Joy) and line with parchment paper for easy removal. Never skip the greasing—this cake sticks without proper prep!

Cooling Gear

A wire cooling rack is essential for even cooling, and I keep a large oval rack from Amazon Basics in my kitchen. For storage, airtight containers (like Rubbermaid Brilliance) preserve moisture better than plastic wrap. The bread slice trick for leftovers works best when stored in a small glass container—just pop in a slice of white bread to absorb excess moisture overnight. 💡

Optional Extras

For chocolate variations, a microplane helps grate dark chocolate quickly, while a pastry brush comes in handy for applying simple syrup glazes. A thermometer (like Thermoworks Thermapen) ensures your melted butter is at the perfect 100°F—too hot and your eggs will scramble. For spice variations, a spice grinder keeps your cinnamon and other spices fresh and potent.
