A note from my kitchen

Before you bake this

This old-fashioned donut loaf has everything I want from the bakery case: a soft vanilla-nutmeg crumb, buttery streusel through the middle and over the top, and a thin glaze that settles around every golden piece.

Yogurt keeps the center especially moist, while the little bit of nutmeg gives it that unmistakable old-fashioned donut flavor.

It is wonderful once the glaze has set, but arguably even better the next day once the crumb, streusel, and glaze have completely settled.

Save me a slice ;)

Thinking out loud

How This Recipe Came About

The cravings, questions, and running commentary behind this bake.

My donut loaf series actually started as a mistake. I was attempting to create a blondie coffee cake, but - as I often do - I pushed the limits and added far too much streusel between the layers and over the top of the batter.

The moment I tasted it, I immediately thought of an old-fashioned donut. The top had become crisp beneath a thin vanilla glaze, giving the loaf an almost fried quality without ever touching a pot of oil. Inside, the middle layer of streusel had settled into the cake and created this dense, decadent texture - almost like an extra-moist cake donut, with the most heavenly buttery sweetness.

Structurally, it was not quite right. The crease through the middle was too pronounced, and I knew I needed to dial a few things back. But honestly, that imperfect crease was arguably the best part. It held so much of the buttery streusel and gave every slice an incredibly rich center.

Instead of forcing the recipe back into the rules of a traditional coffee cake, I decided to follow what it had become. I leaned completely into the donut loaf concept, and after several more iterations, my Old-Fashioned Donut Loaf was born. I added just a hint of nutmeg to give it that familiar old-fashioned warmth without overpowering the vanilla and buttery streusel.

This is still one of my favorite things I have ever created - which is exactly why one loaf eventually became an entire series. It has the crisp glazed top, rich center, and nostalgic flavor of a cake donut, but it is incredibly easy to make and requires no frying. I love serving it as dessert, but it is equally at home on a breakfast or brunch table with a cup of coffee.

From this recipe

Tested notes

01

I test this recipe with Forager Unsweetened Plain Yogurt, Silk Unsweetened Original Soymilk, and Country Crock Plant Butter Sticks. Dairy equivalents can be used at the same listed amounts and temperatures.

02

Fill the loaf pan no more than 3/4 full. It is better to leave a little batter behind than risk overflow.

03

Use the tester as the main doneness guide and insert it into the cake portion rather than the streusel seam.

04

Let the glaze set completely before slicing if you want the best crackly finish.

Ingredient notes

Key ingredients

01

Plain unsweetened yogurt

Yogurt gives the loaf moisture, body, and tenderness. I test this recipe with Forager Unsweetened Plain Yogurt.

02

Milk

I test this recipe with Silk Unsweetened Original Soymilk. Dairy milk can be used at the same listed amount and temperature.

03

Butter sticks

Use butter sticks for the streusel instead of a tub-style spread. I test with Country Crock Plant Butter Sticks, and dairy butter can be used at the same listed amount and temperature.

04

Nutmeg and vanilla bean paste

The nutmeg is intentionally subtle; it creates that classic old-fashioned donut flavor while vanilla bean paste keeps the loaf warm and bakery-like.

05

Coarse sanding sugar

Modern Mountain Baking Company White Sparkling Sugar is my go-to sanding sugar. I get it on Amazon, and it adds a crisp, sparkly finish without melting into the top.

Optional ingredient notes

Use what you have on hand

Curious what I used? These are the exact products I reached for while developing this recipe.

Yogurt

Plain unsweetened yogurt

Plain unsweetened yogurt adds moisture, acidity, and body so the crumb bakes up tender without tasting tangy.

  1. Forager Unsweetened Plain Yogurt

Milk

Milk

Milk affects how smoothly a batter, filling, or frosting comes together. Soy milk and Ripple tend to emulsify well because their protein and fat help create a creamy, cohesive finish.

  1. Silk Original Unsweet

Butter sticks

Butter sticks

Use butter sticks for buttercream and fillings that need to hold their shape.

  1. Country Crock Plant Butter Sticks

Testing notes

Why this works

What binds the loaf without eggs

The yogurt, flour, cornstarch, and sugar work together to give the loaf structure. Yogurt adds moisture and body, while the flour and starch set as the loaf bakes, so eggs are not needed for this style of soft donut loaf.

Why there is apple cider vinegar

The vinegar reacts with the baking soda and helps give the loaf lift. It also balances the sweetness a little. You should not taste vinegar in the finished loaf.

Why room-temperature ingredients matter

Room-temperature yogurt and milk blend more smoothly with the oil and sugar. This helps the batter come together evenly, which gives the loaf a softer crumb and a more even bake.

Why the streusel is chilled

Chilling the streusel keeps the butter cold, so the crumbs hold their shape instead of melting straight into the batter. That is what gives the top its crisp, bakery-style texture.

Why the streusel goes in the middle and on top

The middle layer bakes into a soft buttery ribbon, while the streusel on top stays crisp and clustered. Together they make the loaf feel more like an old-fashioned donut than a plain vanilla loaf.

Why this loaf rests in the pan

A 20-minute pan rest gives the soft center time to settle and makes the loaf sturdy enough to lift out with the parchment without disturbing the streusel.

Why the glaze sets before slicing

Give the loaf about 30 minutes after glazing so the glaze can set. I prefer chilling it, then bringing slices back to room temperature, because that gives the best shatter effect with the glaze and makes the bite feel more harmonious. If you do not want to wait on the chill, letting it set on the counter works too.

Small things that matter

Tips for the best loaf

01

Bring the yogurt and milk to room temperature so the batter emulsifies smoothly.

02

Keep the streusel cold while you make the batter and leave a mix of pea-sized clumps and loose crumbs.

03

Do not press down the streusel on top; the loose, clustered texture is what makes the finished loaf special.

04

Fill the loaf pan no more than 3/4 full, even if you have a little extra batter.

05

Check the loaf after 45 minutes at 350°F and tent it loosely with foil if the streusel is browning too quickly.

06

Use the toothpick test as the main guide: it should come out with moist crumbs, not wet batter. Temperature is a helpful baseline, usually around 205-210°F in the cake portion.

07

Cool the loaf completely before glazing so the coating stays thick enough to set into a crackly finish.

Recipe FAQ

Questions that come up

What makes this an old-fashioned donut loaf?

The soft cake-donut-style crumb, subtle nutmeg, vanilla bean, buttery streusel, and thin set glaze all echo the flavor and texture of an old-fashioned donut.

Is an old-fashioned donut loaf the same as a loaf cake?

It is baked in a loaf pan like a loaf cake, but its subtle nutmeg, tender cake-donut crumb, buttery streusel, and thin set glaze are inspired by an old-fashioned donut. It gives you the flavor and texture of a glazed cake donut without frying.

How do I know when Old-Fashioned Donut Loaf is done?

Use the toothpick test as the main guide. Insert it into the cake portion rather than the streusel seam; it should come out with moist crumbs, not wet batter. An internal temperature around 205-210°F is a helpful baseline.

Can I use dairy ingredients in this donut loaf?

Yes. I test this recipe with Forager Unsweetened Plain Yogurt, Silk Unsweetened Original Soymilk, and Country Crock Plant Butter Sticks. Dairy equivalents can be used at the same listed amounts and temperatures.

Why should the streusel stay cold?

Cold butter helps the streusel hold its clusters instead of melting into the batter. Keep it chilled until you are ready to layer the loaf.

Is Old-Fashioned Donut Loaf better the next day?

It is excellent once the glaze sets, but the crumb, streusel, and glaze settle together overnight, making the next-day loaf especially good.

Can I make this recipe gluten-free?

I have not tested this recipe with gluten-free flour, so I cannot guarantee the same texture, rise, or structure. If you would like to experiment, a cup-for-cup (1:1) gluten-free baking blend intended to replace all-purpose flour is the best place to start. Results may differ from the recipe as written.

Can I use Greek yogurt in this donut loaf?

I do not recommend it. Greek yogurt is much thicker and contains less moisture than the plain unsweetened yogurt used here, which can make the batter too thick and the finished loaf denser or drier. Use regular plain unsweetened yogurt for the texture this recipe was designed to have.

Can I substitute sour cream for the yogurt?

Yes, regular full-fat sour cream is the closest substitute. Replace the plain unsweetened yogurt with the same amount by weight. Sour cream is thicker and higher in fat, so the batter may be slightly thicker and the finished loaf a little richer and denser than the version I tested with yogurt. Avoid reduced-fat or fat-free sour cream, which can behave differently.
