Makes 1 Loaf (10–12 Slices)  •  Beginner Friendly  •  Discard-Powered  •  Ready in ~1 Hour 25 Minutes

Here's the thing nobody tells you about sourdough discard vanilla pound cake: the discard isn't just there to use something up. It's the reason this cake is so tender.

A classic pound cake can go dry fast. This one doesn't — the discard adds moisture and a whisper of tang that makes the vanilla taste more like vanilla.

🍰 Sourdough Discard Vanilla Bean Pound Cake

Cake Batter

• 240 g sourdough discard (about 1 cup, unfed is perfect, at room temperature)
• 250 g all-purpose flour (about 2 cups)
• 227 g unsalted butter (about 1 cup, 2 sticks, softened)
• 200 g granulated sugar (about 1 cup)
• 4 large eggs, at room temperature
• 240 g plain full-fat Greek yogurt (about 1 cup), at room temperature
• 15 g vanilla bean paste (about 1 tablespoon) or the seeds of 1 vanilla bean plus 1 teaspoon vanilla extract
• 8 g baking powder (about 2 teaspoons)
• 5 g fine sea salt (about 1 teaspoon)

Vanilla Glaze (Optional)

• 120 g powdered sugar (about 1 cup)
• 30–45 g milk (about 2–3 tablespoons)
• 2.5 g vanilla extract (about ½ teaspoon)

🥣 Step 1: Prep the Pan & Whisk the Dry Ingredients

Heat your oven to 325°F (165°C). Grease a 9×5-inch loaf pan and line it with parchment, leaving overhang on the long sides for easy lifting.

In a medium bowl, whisk together the flour, baking powder, and salt. Set it aside.

Beginner Tip: Room-temperature butter, eggs, and yogurt are not a suggestion here — they're the whole game. Cold ingredients don't cream properly. Set everything out 30–45 minutes before you start.

🧈 Step 2: Cream the Butter & Sugar

In a large bowl, beat the softened butter and granulated sugar together for 3–4 minutes, until the mixture turns noticeably paler, fluffy, and almost whipped-looking.

Don't rush this step. Those tiny air pockets you're beating in are what keep a pound cake tender instead of brick-like.

🥚 Step 3: Add the Eggs & Vanilla

Beat in the eggs one at a time, mixing well after each one before adding the next. Then beat in the vanilla bean paste (or the scraped vanilla seeds plus extract) until the batter is fragrant and flecked with those gorgeous black specks.

Slightly curdled-looking batter here is normal — it smooths out in the next step.

🥄 Step 4: Fold in the Discard & Yogurt

Stir in the sourdough discard and Greek yogurt and mix just until combined. The batter will look thick and glossy.

🍰 Step 5: Add the Flour & Bake

Add the flour mixture in two additions, mixing on low speed or by hand just until no dry streaks remain. Do not overmix — the moment the flour disappears, stop.

Pour the thick batter into your prepared pan and smooth the top with a spatula. Bake for 55–65 minutes, until the top is deep golden brown with the classic crack down the center, and a toothpick poked into the middle comes out clean or with just a few moist crumbs.

Watch the clock, not just the color: ovens lie. Start checking at 55 minutes, and tent loosely with foil if the top browns too fast.

❄️ Step 6: Cool Before You Slice

Let the cake cool in the pan for 15 minutes, then lift it out with the parchment overhang and cool completely on a wire rack — at least 45 minutes — before slicing. A warm pound cake crumbles when sliced; a cooled one cuts into clean slabs.

For the glaze, whisk the powdered sugar, milk, and vanilla until smooth and pourable, then drizzle over the cooled cake. Let it set for 20 minutes before serving.

👩🍳 Squirrelly Girl Baker's Tips

🍰 1. Vanilla bean paste is the shortcut to speckles — the look and flavor of a scraped bean without the scraping. Extract works too (a full tablespoon), but without the flecks.

🧈 2. The creaming step is non-negotiable. Under-creamed butter and sugar means a dense, squat loaf. Pale and fluffy is the target.

🥄 3. Don't overmix after the flour goes in. Overmixed batter turns a tender cake tough. Stir until just combined and walk away.

🌡️ 4. A toothpick beats a timer. Every oven runs a little different. Clean, or a few moist crumbs, is the only doneness test that matters.

🍓 5. Serve it your way. Plain with coffee is perfect. Fresh berries and whipped cream turn it into dessert. A drizzle of glaze makes it look bakery-made.

🧊 Make It Ahead

This cake keeps up to 4 days at room temperature in an airtight container, and it actually tastes better on day two, once the vanilla has settled into the crumb.

To freeze, wrap cooled, unglazed slices individually, then tuck them into a zip-top bag with parchment between layers. Freeze for up to 3 months. Thaw at room temperature for about an hour.

Reheat like this: a slice in a 300°F oven for 5–8 minutes. Glaze after reheating, not before freezing.

🚨 Vanilla Pound Cake Troubleshooting

My cake sank in the middle.

It was likely underbaked, or the oven door was opened too early. Bake until the toothpick test truly passes.

My cake is dry.

It probably baked a few minutes too long, or the flour was over-measured. Spoon flour into your measuring cup and level it off — scooping packs in extra flour.

My cake is dense and heavy.

The butter and sugar probably weren't creamed long enough, or the batter was overmixed after the flour went in. Cream for the full 3–4 minutes, then mix the flour in gently.

My cake stuck to the pan.

Parchment is your best friend here. Grease plus a parchment sling means the cake lifts out cleanly every time.

The vanilla flavor is faint.

Use vanilla bean paste or a real scraped bean next time — far more flavor than extract alone. A pinch of salt also wakes vanilla up, so don't skip it.

⚠️ Baker's Warning

Making a pound cake this good has a predictable side effect.

Suddenly you're the person who "just whips up a cake" for every gathering.

And once people taste those vanilla specks…

You're officially the cake person.

❓ FAQ: Sourdough Discard Vanilla Pound Cake

Can I use active starter instead of discard?

Yes — active starter works the same here and may rise a touch more. Discard is still the move: it would otherwise go unused, and the gentle tang is perfect in a pound cake.

Does sourdough discard make pound cake taste sour?

Not when it's fresh. Discard less than a week old adds depth and moisture, not sourness.

Can I use vanilla extract instead of vanilla bean paste?

Absolutely. Use a full tablespoon of good-quality extract. You'll lose the black speckles, but the flavor will still be rich and warm.

Why did my pound cake crack on top?

That crack is a good sign — it's the classic pound cake crown, caused by the outside setting while the inside keeps rising.

❤️ Happy Baking!

Cream the butter.

Speckle it with vanilla.

Save the discard.

Wait for it to cool (the hard part).

And prepare for the kind of cake that makes everyone ask, "You made this yourself?"
