Ingredients for all in one cake
Nine simple ingredients transform into a foolproof cake with no mixing bowls needed.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Unsalted Butter 🧈 | 1 cup | Room temperature, full-fat |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Vanilla Extract 🌸 | 1 tbsp | Pure extract, not imitation |
| Milk 🥛 | 1 cup | Whole milk preferred |
| Baking Powder 🍞 | 2 tsp | Freshly opened package |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Vegetable Oil 🫒 | ¼ cup | Light or canola oil |
| Powdered Sugar 🍰 | ½ cup | For optional topping |
Flour is the backbone here—King Arthur or Gold Medal are my go-tos for consistent results. The butter must be room temperature (press a finger into it; if it leaves a dent, it's ready). Eggs should be at room temperature too for even mixing. For the milk, whole milk gives the best texture, but 2% works in a pinch. The baking powder is non-negotiable—if your package is old, test it first by mixing with water (should bubble). Vanilla extract is where flavor magic happens—Nielsen-Massey is my top pick, but any pure extract will do.
No vanilla extract? Almond extract at half the amount works surprisingly well. Short on butter? Substitute with oil (reduce milk by 2 tbsp to compensate). The powdered sugar topping is optional but adds that restaurant-quality finish—Domino or C&H brands are reliable. For a chocolate twist, swap 0.5 cup of the flour for Dutch-process cocoa powder. Need extra moisture? Add 2 tbsp sour cream to the batter. The vegetable oil keeps the cake tender—don't skip it even if you're using butter.
Store baked cake in an airtight container at room temperature for up to 3 days, or freeze for 3 months. The batter can be mixed ahead and refrigerated for 24 hours—just let it sit at room temperature for 30 minutes before baking. For elegant presentation, dust with powdered sugar or drizzle with melted white chocolate. Leftovers? Toasted almond slices on top make any slice feel special.
Why You'll Love This Recipe
- No Mixing Madness: I swear by this one-bowl method—just cream butter and sugar, toss in dry ingredients, then fold in eggs. No sifting, no measuring cups flying everywhere. My kids even "help" (read: dump flour everywhere) and we still end up with a cake.
- Vanilla Butter Bliss: That rich, buttery crumb? Unmatched. The vanilla extract cuts through the sweetness just enough to make every slice feel like a little indulgence. Honestly, the first time I tried it, I ate half the batter raw. (Don’t judge.)
- One Cake, Many Ways: Bake it for breakfast with a drizzle of honey, turn it into trifle layers, or serve it warm with ice cream. I’ve even used the leftovers for cake pops—because why let good cake go to waste? Works for birthdays, potlucks, or just because.
- Pantry Staple Magic: You’re already using what’s in your cupboard: flour, sugar, butter, eggs, and a splash of vanilla. No specialty ingredients, no last-minute grocery runs. My budget stays happy, and my freezer stays stocked with slices ready for whenever the craving hits.
Step-by-step instructions for all-in-one cake recipe
This one-bowl wonder combines everything in a single container for effortless baking.
👨🍳 Step 1: Mix Wet Ingredients Until Smooth
In a large mixing bowl, combine the 1 cup unsalted butter (room temperature) with the 1.5 cups granulated sugar. Using an electric mixer on medium speed, beat for 2-3 minutes until the mixture becomes pale and fluffy. This lightens the texture and incorporates air—critical for that tender crumb.
Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1 tbsp vanilla extract and 1 cup milk. Scrape down the sides of the bowl with a spatula to ensure all ingredients are fully incorporated. The batter should be smooth with no visible lumps at this stage.
👨🍳 Step 2: Incorporate Dry Ingredients Gently
In a separate bowl, whisk together the 2 cups all-purpose flour (sifted), 2 tsp baking powder, and 0.5 tsp salt. With the mixer on low speed, gradually add the dry ingredients to the wet mixture. Mix just until combined—about 30-45 seconds—to avoid developing gluten that would make the cake tough.
Next, pour in the 0.25 cup vegetable oil and mix on low speed for another 10-15 seconds until the batter is completely homogeneous. The oil helps create a moist crumb, and this step ensures even distribution. Stop mixing as soon as the batter comes together—overmixing is the enemy of tender cakes.
🔥 Step 3: Prepare the Pan and Pour the Batter
Preheat your oven to 350°F and grease an 8-inch round cake pan or 9x13-inch baking dish thoroughly with butter or nonstick spray. Line the bottom with parchment paper if needed, especially for round pans. This prevents sticking and makes for easier removal.
Pour the batter into your prepared pan and smooth the top with a spatula. For an even bake, tap the pan gently on the countertop to release any air bubbles. If using a round pan, you can also use a skewer to pop any large bubbles that rise to the surface. The batter should fill the pan to about ¾ inch depth.
⏰ Step 4: Bake Until Golden and Springy
Place the cake pan in the center rack of your preheated oven and bake for 30-35 minutes for a round cake or 25-30 minutes for a sheet cake. The cake is done when a toothpick inserted in the center comes out clean or with just a few moist crumbs clinging to it.
Watch for visual cues—the edges should be light golden brown and the center should spring back slightly when pressed gently with a finger. If the top browns too quickly, tent loosely with aluminum foil after 20 minutes to prevent over-browning while allowing the center to cook through.
🍽️ Step 5: Cool and Finish with Optional Powdered Sugar
Remove the cake from the oven and let it cool in the pan for 10 minutes before transferring to a wire rack to cool completely. This gradual cooling prevents cracking and allows the cake to set properly. For best results, let it cool for at least 1 hour before slicing.
If desired, dust the cooled cake with the 0.5 cup powdered sugar through a fine-mesh sieve for a classic finish. This step is optional but adds that final touch of elegance. Serve at room temperature for the perfect balance of tender crumb and moist texture—this cake tastes best when enjoyed fresh from the oven or at least slightly warm.
Pro Tips For Making All In One Cake
- CREAM BUTTER FIRST: Mix the softened butter and sugar until it’s pale yellow—about 3-4 minutes with a stand mixer. I learned this the hard way: rushing it leaves dense cake, and skipping it means you’ll taste raw butter. (Yes, even if you’re impatient like me.)
- WEIGH EGGS ACCURATELY: Use a kitchen scale for eggs—1 large egg weighs ~50g, but size varies. I was skeptical until I tried it: overestimating eggs makes the cake gummy; underestimating makes it dry. (Your future self will thank you.)
- STOP WHEN TESTED DONE: Pull the cake when the center hits 205°F (96°C) on an instant-read thermometer—not when it looks set. After burning three batches, I finally figured out: oven temps lie, and overbaking turns moist cake into cardboard.
- SWAP VANILLA FOR EXTRA FLAVOR: Skip imitation vanilla and use 1 teaspoon of pure vanilla extract—or better, scrape the seeds from a split pod. Sounds weird, but it works: the depth of flavor makes a real difference, especially in simple recipes like this.
Common mistakes when making great all in one cake
Overmixing the Batter
This is the #1 mistake that turns tender cake into dense brick! Once you add the dry ingredients, mix only until just combined—about 30-45 seconds on low speed. Overmixing develops gluten, which creates a tough, chewy texture. I’ve seen beginners mix for 2-3 minutes by accident, and the result? A cake that’s more bread-like than dessert. 💛
Pro tip: Use a spatula to fold in the last 10% of flour by hand if your mixer tends to overwork the batter. The moment the batter comes together smoothly is the perfect stopping point—no streaks, no lumps, just a homogenous ribbon when the spatula lifts.
Skipping Room-Temp Ingredients
Cold butter or eggs can create pockets of uneven texture in your cake. If your butter has white streaks or your eggs are straight from the fridge, let them sit at room temperature for 30-60 minutes before mixing. Cold ingredients don’t emulsify well, leading to a cake with oily patches or a grainy crumb. I learned this the hard way—my first attempt with fridge-cold butter resulted in a cake that looked like it had marble swirls instead of a smooth finish.
Test butter readiness by pressing your finger into it: if it leaves a clear dent, it’s perfect. For eggs, roll them gently between your palms to warm them up slightly. This small step makes all the difference in texture.
Incorrect Pan Prep
Greasing your pan is non-negotiable, but uneven greasing or skipping parchment paper leads to sticking and uneven baking. Use butter + flour (rub butter, then dust with flour) or nonstick spray for even coverage. For round pans, parchment paper on the bottom prevents the cake from browning too quickly on the edges. I’ve had cakes stick so badly they tore when removing—always double-check your pan prep!
For sheet cakes, lightly grease the pan but don’t overdo it—excess grease can make the cake too moist and gummy. A light film is all you need. And if you’re baking in a glass pan, reduce oven temperature by 25°F to prevent over-browning.
Baking Time Guesses
Every oven is different, so relying on exact minutes (like the recipe’s 30-35 minutes) without checking don’t work. The cake is done when a toothpick comes out clean or with a few moist crumbs—not when the timer dings. I’ve pulled cakes too early (dry, crumbly) and too late (burnt edges, raw center). For 9x13-inch pans, start checking at 25 minutes; for 8-inch rounds, wait until 30 minutes.
If the top browns too fast, tent with foil after 20 minutes and continue baking. The center should spring back slightly when pressed gently—if it bounces back quickly, it’s overdone. Underbaked cakes sink in the middle as they cool, so err on the side of slightly underbaking if you’re unsure.
Ignoring Cooling Time
Transferring a hot cake to a wire rack too soon causes cracks or a domed top as it cools unevenly. Let it rest in the pan for 10-15 minutes first, then transfer. I’ve seen cakes split open like a volcano because they were moved too quickly. For layered cakes, cool completely before frosting to avoid soggy layers from melted butter.
Patience pays off: a cake cooled for 1 hour before slicing holds its shape and tastes moist and tender, not dry. If you’re in a hurry, slice after 30 minutes of cooling, but expect slightly softer edges. For powdered sugar topping, always apply to a completely cooled cake to avoid melting.

Frequently asked questions
Can I make this cake without an electric mixer?
Use a sturdy wooden spoon or whisk for the wet ingredients—just beat the butter and sugar vigorously for 3-4 minutes until light and fluffy. For the dry ingredients, fold them in gently with a spatula until just combined. The key is patience—mix until the batter is smooth but not overworked. This method works perfectly for one-bowl simplicity.
How do I adapt this recipe for a gluten-free diet?
Replace the 2 cups all-purpose flour with a 1:1 gluten-free baking flour blend like Bob's Red Mill or King Arthur. Add 1 tsp xanthan gum to help bind the crumb. For best results, also swap the baking powder with a gluten-free baking powder (some blends contain wheat). The texture will be slightly denser but still moist and delicious.
Can I bake this cake in a different-sized pan?
Yes, but adjust the baking time and temperature. For a 9-inch round pan, bake at 350°F for 35-40 minutes. For a 9x13-inch pan, reduce oven temp to 325°F and bake for 25-30 minutes. The cake should fill the pan ¾ full. For odd shapes, use the toothpick test—it’s the most reliable indicator of doneness.
What's the best way to store leftover cake?
Wrap individual slices tightly in plastic wrap or store the whole cake in an airtight container at room temperature for up to 3 days. For longer storage, freeze slices wrapped in plastic for 3 months. Thaw at room temperature for 1-2 hours before serving. The texture stays moist when stored properly—no dry crumbs here!
Can I add mix-ins like chocolate chips or nuts?
Fold in 1 cup chocolate chips or ½ cup chopped nuts during the final 10 seconds of mixing. For even distribution, use a spatula to gently swirl them through the batter. Pro tip: If adding nuts, toast them first for 3-5 minutes at 350°F to enhance their flavor. Just don't overmix after adding mix-ins!
