Ingredients for all purpose cake
Precise ratios and quality ingredients create the perfect moist crumb and elegant vanilla swirl.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for even texture |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Unsalted Butter 🧈 | 1 cup | Room temperature, full-fat |
| Large Eggs 🥚 | 3 whole | Room temperature, separated |
| Vanilla Extract 🌸 | 2 tsp | Pure, high-quality extract |
| Baking Powder 🧂 | 2 tsp | Diamond Crystal preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Milk 🥛 | 1 cup | Whole milk preferred |
| Vanilla Bean Paste 🌸 | 1 tbsp | For swirl, optional |
| Vanilla Cake Mix 🍰 | 15 ¼ oz | Or homemade equivalent |
| Vegetable Oil 🫒 | ½ cup | Light, neutral flavor |
The flour and sugar ratio is critical for that signature tender crumb—don't substitute cake flour here. King Arthur or Gold Medal brands work best for consistent results. The butter should be soft enough to press with a finger but not greasy; let it sit at room temperature for 1-2 hours. Eggs at room temperature mix more smoothly and create a lighter texture. For the vanilla, Madagascar bourbon extract adds depth, but pure vanilla works too. The baking powder is non-negotiable—Diamond Crystal is more potent than others, so use exactly 2 tsp.
No vanilla extract? Vanilla bean paste works beautifully for the swirl—just swirl it in before baking. Substituting milk? Oat milk or almond milk will work, but the cake may be slightly less tender. Want to make this chocolate? Replace 1 cup flour with 6 oz Dutch-process cocoa powder and add 1/4 cup extra oil. For a citrus twist, add 1 tbsp lemon or orange zest with the dry ingredients. The vegetable oil keeps the cake moist longer than butter alone, but if you prefer, use melted coconut oil instead.
Store baked cake in an airtight container at room temperature for up to 3 days for best texture. For longer storage, wrap tightly and refrigerate for 1 week or freeze for 3 months. The vanilla swirl stays vibrant if you add a thin layer of apricot jam before baking—it keeps the moisture in. To reheat, wrap in a damp towel and microwave for 10-15 seconds for a fresh-from-oven experience.

Step-by-step instructions for all-purpose cake recipe
This method delivers a perfectly moist crumb with a delicate vanilla swirl every time.
Prepare the Vanilla Swirl Dough
In a medium mixing bowl, combine the 15.25 oz vanilla cake mix, 2.5 cups all-purpose flour, and 2 tsp baking powder. Whisk until evenly distributed, breaking up any lumps in the cake mix. This ensures an even texture throughout the cake.
In a separate small bowl, mix the 1 cup unsalted butter (softened to room temperature), 2 cups granulated sugar, and 1 cup milk until smooth and fully incorporated. Add the 3 whole large eggs one at a time, whisking vigorously after each addition to maintain an airy consistency. This step creates the foundation for your cake's moisture and structure.
Divide the combined dry ingredients into two equal portions. To one portion, add the wet mixture and mix until just combined. This creates your base dough. To the second portion, add the 2 tsp vanilla extract and 1 tbsp vanilla bean paste, mixing until fully incorporated. This portion will become your vanilla swirl dough.
Create the Swirl Pattern
Lightly grease a 9-inch round cake pan and line the bottom with parchment paper. Spread half of the base dough evenly into the prepared pan, pressing down gently to create an even layer. This ensures the cake bakes uniformly and prevents sinking.
Drop spoonfuls of the vanilla swirl dough evenly over the base layer, spacing them about 1 inch apart. Use a butter knife to gently swirl the vanilla dough into the base, creating a marbled effect. This technique creates the signature vanilla swirl while maintaining the cake's structure.
Cover the swirled cake with the remaining base dough, pressing down lightly to seal. Smooth the top with a spatula, ensuring an even surface. This final layer ensures the cake holds its shape during baking and creates a clean finish.
Bake to Perfect Moisture
Preheat your oven to 350°F and place the prepared cake pan in the center rack. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. The cake should be golden brown at the edges but still slightly springy in the center.
I've found that baking time varies slightly depending on your oven, so start checking at the 28-minute mark. Overbaking is the quickest way to dry out your cake, so remove it as soon as it passes the toothpick test. The residual heat will continue cooking the center slightly.
Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. This gradual cooling process prevents cracking and helps set the cake's structure for perfect slicing.
Finish with Moisture-Preserving Techniques
Once the cake has cooled completely, brush the top and sides with a simple syrup made by heating ½ cup granulated sugar with ¼ cup water until dissolved. This step is crucial for maintaining moisture in the cake for up to 3 days when stored properly.
For an extra touch, dust the top with powdered sugar or add a thin layer of vanilla glaze. The cake's texture should be tender with a fine crumb, not dense or crumbly. Each slice should reveal the beautiful vanilla swirl pattern throughout, proving your technique worked perfectly.
Pro Tips For Making All Purpose Cake
- Weigh Your Butter: I learned this the hard way—measuring butter by scooping it straight from the fridge leads to inconsistent volumes. Use a kitchen scale for 225g (1 cup) of unsalted butter, packed lightly but not compressed. Packed butter rises when melted, and that’s the difference between a cake that’s too dense or too airy.
- Mix Dry Ingredients First: Skip the urge to toss everything into the bowl at once. Whisk the flour, sugar, and any dry leavening (like baking powder) together first—this prevents lumps when you add the wet ingredients. I used to mix them in order, and I’d end up with a gritty texture that ruined the crumb.
- Room-Temp Eggs Matter: Cold eggs won’t incorporate properly, and your cake will turn out gummy. Pop the eggs in warm water for 5 minutes before cracking them—just enough to bring them to about 70°F (21°C). Warm eggs blend smoothly and create a lighter batter, which means a better rise.
- Bake Until Cool Center: The instant-read thermometer is your friend here. An all-purpose cake should hit 205–210°F (96–99°C) at the center—yes, that’s hotter than you think. Pulling it out too soon leaves a raw middle that feels sad in every bite. Let it cool in the pan for 10 minutes first, then transfer to a rack.
Essential equipment for perfect results
Must-Have Mixing Tools
Start with a 9-inch round cake pan—I recommend Wilton Perfect Results pans for their even heat distribution. For mixing, a stand mixer with a whisk attachment (like the KitchenAid Artisan Series) makes this recipe effortless, but a hand mixer works too if you're on a budget. The whisk attachment ensures you don't overmix the batter, which is critical for that tender crumb. 🌟
Essential Measuring Gear
Precision matters in baking! Use stainless steel measuring cups (like OXO Good Grips) for dry ingredients and a digital kitchen scale (I love the Escali Primo) for accurate butter and sugar measurements. A microplane comes in handy for zesting citrus if you're adding a bright twist. Avoid glass measuring cups—they can crack under oven heat.
Oven Thermometer
Your oven's temperature gauge is often inaccurate. A Thermoworks Oven Thermometer (around $15) will show you the real heat, preventing under- or overbaking. I've ruined cakes before by trusting my oven's dial—this small investment saves time and frustration. Place it in the center rack while preheating to calibrate.
Swirl Tools
For the signature swirl, grab a small offset spatula (like Mercer Culinary Genesis) and a butter knife for spreading. A piping bag with a star tip (optional) makes clean swirls if you prefer more control. The key is gentle pressure—you want to marble, not force, the dough together. Practice on parchment first if you're new to this technique!
Cooling Accessories
A wire cooling rack (I use OXO Good Grips) is non-negotiable—it prevents soggy bottoms. For long-term storage, vacuum-seal bags (like FoodSaver) keep the cake fresh for weeks. And if you're glazing, a fine-mesh sieve helps dust powdered sugar evenly. Pro tip: Let the cake cool in the pan for 10 minutes before transferring to avoid cracks.
Optional Upgrades
Want to take it further? A cake tester (like Wilton's) ensures perfect doneness without guessing. For decorating, Wilton's Decorating Set includes everything from piping bags to edible pearls. If you're making this often, a second cake pan lets you bake two layers simultaneously—ideal for tiered cakes. These extras turn this recipe into a bakery-quality masterpiece! 💫

Frequently asked questions
Can I make this cake without a stand mixer?
While a stand mixer makes mixing easier, you can achieve the same results with a hand mixer or even a whisk. Just mix the ingredients on low speed to avoid overmixing, which can make the cake dense. A sturdy whisk and strong arm work too—just take your time to combine everything smoothly.
How do I adapt this recipe for a chocolate version?
Replace 1 cup of flour with 6 oz Dutch-process cocoa powder and add 1/4 cup extra vegetable oil to keep it moist. Use 1.5 tsp vanilla extract and reduce the milk to 3/4 cup to balance the richness. The swirl technique works perfectly with chocolate too!
Why did my cake turn out dense?
Overmixing is the most common cause—stop mixing as soon as the ingredients are combined. Another culprit could be using cold eggs or butter, which don't incorporate air properly. Always ensure your butter is room temperature and eggs are at room temperature before mixing. Also, check that your baking powder is fresh!
Can I bake this cake in a different pan size?
Yes, but you'll need to adjust the baking time. For an 8-inch pan, reduce time by 5-7 minutes and for a 10-inch pan, increase by 5-7 minutes. The key is to bake until a toothpick comes out clean. Line the pan with parchment paper to prevent sticking and ensure even baking.
How do I store leftovers to keep them moist?
Wrap the cake tightly in plastic wrap or place it in an airtight container with a slice of bread to absorb excess moisture. Store at room temperature for 2-3 days or refrigerate for up to 1 week. For longer storage, freeze slices wrapped individually for up to 3 months.
