Ingredients for all in one cake

Eight simple ingredients transform your kitchen into a bakery with minimal effort and zero stress.

The flour is your foundation—King Arthur or Gold Medal brands work best for that tender crumb. Grab a 5-pound bag from Walmart or Target if you're baking often, but a single container works too. Butter matters here—Land O'Lakes or Plugrá are reliable, but never use margarine. Room temperature is key: let it sit out for 30 minutes before measuring. The eggs? Cage-free from the grocery store are fine, but if you're feeling fancy, Pasture-Raised from the farmers market add extra richness. The vanilla extract should smell potent—Nestlé or McCormick are solid choices, but avoid imitation vanilla.

No baking powder? Baking soda plus cream of tartar works (use 1.5 tsp baking soda + 0.5 tsp cream of tartar). Short on milk? Eggnog or heavy cream adds decadence, but almond milk works in a pinch. The sugar can be swapped for coconut sugar or brown sugar—just know it'll change the color slightly. Need to make this gluten-free? Bob's Red Mill 1:1 Gluten-Free Flour Blend replaces the all-purpose flour perfectly. And if you're wondering about the salt: Diamond Crystal kosher salt measures perfectly, but regular table salt works if you cut the amount by half.

Store your flour in an airtight container for up to 6 months, butter in the fridge for 3 months (or freeze for 6 months), and vanilla extract in a cool, dark place for 2 years. The milk should be used within 5 days once opened. For extra convenience, pre-measure your dry ingredients in a ziplock bag—just dump them into your bowl when ready. This batter keeps in the fridge for 24 hours before baking, so you can prep ahead for busy mornings. And if you're making layers? Divide the batter evenly between pans before baking.

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

Here's how to create a flawless cake with just one bowl and minimal effort.

Start by sifting the 2.5 cups all-purpose flour directly into your mixing bowl. This aerates the flour and prevents lumps in your batter. I like to use a fine-mesh sieve for this step—it ensures an even distribution of baking powder throughout the flour.

In a separate small bowl, whisk together the 2 tsp baking powder and 0.5 tsp salt. This pre-mixing prevents clumping when you combine everything later. While you're at it, measure out the 1.5 cups granulated sugar and set it aside with the 1 tbsp vanilla extract and 1 cup milk—having everything prepped means no mid-recipe scrambling.

In your mixing bowl with the sifted flour, add the 1 cup softened unsalted butter and 1.5 cups granulated sugar. Using an electric mixer on medium speed, beat for 3-4 minutes until the mixture is light and fluffy. You'll see it nearly double in volume and become pale in color—this incorporates air that will help your cake rise beautifully.

Here's the thing—I always check the butter consistency before starting. It should be soft enough to leave a slight indentation when pressed, but not greasy. If it's too hard, let it sit at room temperature for 10-15 minutes before proceeding. The right temperature ensures proper emulsification with the sugar.

Add the 3 whole large eggs, one at a time, mixing on low speed for 30 seconds after each addition. This gradual incorporation prevents the eggs from scrambling. After all eggs are added, increase the speed to medium and mix for another 1 minute until the mixture is smooth and creamy.

Now stir in the 1 tbsp vanilla extract using a spatula. I like to scrape the sides of the bowl to ensure all the flour is fully incorporated. The batter should be thick but pourable—if it looks too stiff, you can add 1-2 tablespoons of the milk to loosen it slightly. This is your last chance to adjust consistency before baking.

Pour in the 1 cup milk and mix on low speed for 30-45 seconds until just combined. Be careful not to overmix—you should still see some flour streaks. The batter will be thick but should hold its shape when spooned.

While the batter rests for 5 minutes, preheat your oven to 350°F and grease an 8-inch round cake pan or 9x13-inch baking dish with butter or nonstick spray. Line the bottom with parchment paper for easy removal. I always use parchment because it prevents sticking and makes cleanup a breeze.

Pour the batter into your prepared pan and smooth the top with a spatula. Bake in the preheated oven for 30-35 minutes (for an 8-inch cake) or 35-40 minutes (for a 9x13-inch cake) until a toothpick inserted in the center comes out clean. The edges should be golden brown, but don't overbake—the cake will continue cooking slightly as it cools.

I know it's tempting to check early, but resist! The cake needs the full time to develop proper structure. When it's done, remove from the oven and let it cool in the pan for 10 minutes, then transfer to a wire rack to cool completely. This resting period prevents cracking as the cake cools. Serve warm or at room temperature for the best texture.

Creative variations of this all in one cake

Classic Vanilla Twist

Start with the base recipe but infuse the batter with 1 tsp lemon zest and 1 tbsp lemon juice for a bright, citrusy twist. The acidity enhances the vanilla flavor while keeping the cake moist. I love adding ½ cup white chocolate chips to the batter for pockets of decadence—just fold them in after mixing the wet ingredients. 🌸

Chocolate Lover's Version

Swap ½ cup of the all-purpose flour for ½ cup unsweetened cocoa powder and reduce the milk to ½ cup. Add ½ cup semi-sweet chocolate chunks or chocolate hazelnut spread for a Nutella-inspired treat. For extra richness, replace 2 tbsp of the butter with 2 tbsp melted dark chocolate. This version tastes like a cross between a brownie and cake!

Spiced Chai Cake

Transform your cake into a cozy chai-inspired dessert by adding 1 tsp ground cinnamon, ½ tsp ground cardamom, ¼ tsp ground ginger, and ¼ tsp ground cloves to the dry ingredients. For warmth, fold in ½ cup chopped toasted pecans or walnuts after mixing. Serve with a dollop of whipped cream and a sprinkle of cinnamon sugar for an aromatic treat.

Fruit-Infused Layers

For a fruity twist, fold in 1 cup mixed berries (like raspberries or blueberries) or diced peaches into half the batter before dividing it into two pans. Bake as directed, then layer with whipped cream or Greek yogurt and fresh fruit. You can also use 1 cup of canned pineapple chunks (drained) for a tropical vibe—just toss them in 1 tbsp flour before folding into the batter.

Gluten-Free Adaptation

Replace the 2.5 cups all-purpose flour with 2.5 cups Bob’s Red Mill 1:1 Gluten-Free Flour Blend and add 1 tbsp xanthan gum to the dry ingredients. For extra moisture, increase the milk to 1.25 cups. This version holds up beautifully for layer cakes or cupcakes. Pair it with a dairy-free frosting made from coconut cream and maple syrup for a fully inclusive treat.

Seasonal Holiday Cake

Celebrate the holidays by adding ½ cup crushed peppermint candies (for Christmas) or ½ cup chopped candied ginger (for winter). For a festive touch, swirl in red and green sprinkles or edible gold dust after baking. You can also make a spiced rum version by replacing ½ cup of the milk with ½ cup spiced rum—just bake immediately to avoid alcohol evaporation. 🎄
