Moist One-Bowl Vanilla Loaf Cake
This vanilla loaf cake is the kind of cake you make on a random Tuesday, when you want something sweet with almost no cleanup.
It’s tender, fragrant with real vanilla, and stays moist for days thanks to melted butter that does all the work.
What Makes This Loaf Cake So Good
The melted butter keeps the crumb soft and eliminates the mixer. You whisk everything together in one bowl, and the cake tastes like it took far more effort.
A generous two teaspoons of real vanilla means every bite carries that warm, floral note. It’s simple and exactly what you want from a vanilla loaf.
Ingredients
- 1/2 cup unsalted butter, melted and slightly cooled: melted butter makes the cake tender and means no mixer needed.
- 1 cup granulated sugar: for a fine, even crumb.
- 2 large eggs, room temperature: cold eggs can cause the melted butter to seize.
- 2 teaspoons pure vanilla extract: use the real stuff for that floral depth.
- 1 1/2 cups all-purpose flour: spooned and leveled, not scooped.
- 1 1/2 teaspoons baking powder: for lift.
- 1/4 teaspoon fine salt: brings the sweetness into focus.
- 1/2 cup whole milk, room temperature: buttermilk works beautifully here too.
Variations
- Brown Butter: cook the butter in a pan until it smells nutty and the milk solids turn amber. Let it cool before using.
- Lemon Vanilla: add the zest of 1 lemon to the sugar and rub it in with your fingers before whisking.
- Almond: replace 1 teaspoon of vanilla with 1/2 teaspoon almond extract.
- Dairy-free: swap the butter for melted coconut oil and the milk for oat milk.

How to Make Moist One-Bowl Vanilla Loaf Cake
Step 1: Mix the Wet Ingredients
Preheat the oven to 350°F (175°C) and grease an 8×4-inch loaf pan. Line the bottom with parchment for easy lift-out. In a large bowl, whisk the 1/2 cup melted butter and 1 cup sugar until the mixture looks like wet sand, about 30 seconds. Add the 2 eggs and 2 teaspoons vanilla, then whisk vigorously until the mixture is smooth and slightly thickened.
The batter will be pale yellow and glossy, with a strong vanilla scent. Make sure the butter isn’t hot when you add the eggs; if it’s too warm, the eggs can start to cook.
Step 2: Fold in the Dry Ingredients
Place a sieve over the bowl and sift in the 1 1/2 cups flour, 1 1/2 teaspoons baking powder, and 1/4 teaspoon salt. Fold gently with a rubber spatula until you don’t see dry flour, then pour in the 1/2 cup milk. Continue folding just until the batter comes together and no streaks remain.
Don’t overmix; a few small lumps are fine. The batter will be thick but pourable, a pale cream color.
Step 3: Bake the Cake
Scrape the batter into the prepared pan and smooth the top. Bake for 50 to 55 minutes, or until the top is deeply golden and a toothpick poked into the center comes out with a few moist crumbs.
The cake will spring back lightly when pressed. If the top is browning too quickly, tent it loosely with foil after 35 minutes.
Step 4: Cool and Slice
Let the cake cool in the pan on a wire rack for 10 minutes, then run a knife around the edges and lift it out using the parchment. Cool completely on the rack before slicing.
Slicing while warm can tear the crumb; patience pays off with clean, neat slices. The crust will be slightly crisp, while the inside stays tender and flecked with vanilla seeds.
A Few Notes Before You Start
- Bring eggs and milk to room temperature quickly by placing them in a bowl of warm water for 10 minutes. This keeps the batter from seizing when cold liquid hits the melted butter.
- For a slightly taller, denser loaf, bake at 325°F for 60 to 65 minutes instead. The lower temperature lets the cake rise more evenly.
- Resist the urge to open the oven door before 40 minutes; a sudden drop in temperature can cause the center to sink.
- Use a serrated knife and a gentle sawing motion for clean slices once the cake is fully cool.
Bake times by pan size:
| Pan Size | Bake Time |
|---|---|
| 8×4-inch loaf | 50 to 55 mins |
| 9×5-inch loaf | 45 to 50 mins |
| Mini loaf (3×5) | 25 to 30 mins |
Storing the Cake
Store the cooled loaf tightly wrapped at room temperature for up to 3 days. For longer storage, wrap the whole cake or individual slices well and freeze for up to 2 months. Thaw at room temperature or warm slices in the microwave for 10 seconds to revive that just-baked softness.
What to Serve With Vanilla Loaf Cake
A thick slice is lovely alongside a cup of black coffee or tea, where the cake’s buttery sweetness balances the bitterness. For a simple dessert, warm slices and top with fresh berries lightly mashed with a sprinkle of sugar and a spoonful of whisked cream.
Frequently Asked Questions
Can I use oil instead of melted butter?
Yes, you can replace the melted butter with 1/2 cup neutral oil, like vegetable or avocado oil. The cake will be a touch less rich but still moist.
Can I make this with gluten-free flour?
A 1-to-1 gluten-free flour blend works well here. Avoid blends without xanthan gum; the cake may crumble.
Why did my cake sink in the middle?
A sunken center often means the cake was underbaked or the oven door was opened too early. Make sure the toothpick test comes out with moist crumbs, not wet batter.
Can I turn this into cupcakes?
Absolutely. Divide the batter among a lined 12-cup muffin tin and bake at 350°F for 18 to 22 minutes, until a toothpick comes out clean.
