Donut Loaves
Lemon Raspberry Old-Fashioned Donut Loaf
A bright lemon cake-donut loaf filled with fresh raspberries, layered with buttery streusel, and covered in vanilla crackle glaze.
This lemon raspberry old-fashioned donut loaf has the dense, tender crumb and crackly vanilla glaze of a classic cake donut, with buttery streusel through the center and over the top. Fresh raspberries bake into tart, juicy pockets while lemon zest, juice, and emulsion give the entire loaf a bright, rounded citrus flavor.
It borrows heavily from my original Old-Fashioned Donut Loaf, but the fresh fruit makes it feel completely new. Use firm raspberries, keep the streusel cold, and stop filling the pan just after two-thirds full for the best shape and bake.

Thinking out loud
The Fresh-Fruit Donut Loaf I Almost Did Not Make
The cravings, questions, and running commentary behind this bake.
When I thought of a donut, I did not think of fresh fruit. Fried donuts do not typically have fresh fruit baked inside, and I was convinced adding it would take away from the whole old-fashioned donut experience.
My husband had been asking me to try fresh fruit in these loaves for a while, and I kept pushing back. I am officially reporting that he was right about this one. The first bite still tastes unmistakably like an old-fashioned cake donut, but now there are tart bursts of raspberry and bright lemon running through it.
This recipe stays close to the loaf that started the series, so if you love my original Old-Fashioned Donut Loaf, you will adore this one. It also gave me so many more ideas. From now on, whenever I make an assortment of donut loaves for people, there will always be a fresh-fruit one.

From this recipe
Tested notes
Zest only the bright yellow exterior of the lemon and avoid the white pith.
Lemon zest, juice, and emulsion create a rounded lemon flavor without relying too heavily on any one source. Lemon extract works perfectly well in place of the emulsion.
Use only firm fresh raspberries. Frozen raspberries contain significantly more liquid and are not recommended for this loaf.
Do not fill the pan more than three-quarters full. I stop just after two-thirds full and use any excess batter for muffins or mini loaves.
Fold gently so distinct raspberry pockets remain throughout the loaf.
I use a 9x5-inch Fat Daddio's anodized aluminum loaf pan. It is inexpensive, available on Amazon, and my preferred pan for an even bake.
Ingredient notes
Key ingredients
Fresh raspberries
Use firm fresh raspberries so they are more likely to hold their shape and less likely to bleed into the batter. Frozen raspberries contain significantly more liquid and are not recommended for this loaf.
Fresh lemon zest and juice
The zest brings fragrant lemon oil to the batter, while the juice adds fresh citrus brightness. Zest only the yellow exterior and avoid the bitter white pith.
Lemon emulsion
The emulsion gives the loaf a rounder lemon flavor and aroma. Lemon extract works perfectly well in the same amount if that is what you have on hand.
Plain unsweetened yogurt
Yogurt gives this egg-free loaf moisture, body, and the substantial but tender crumb of an old-fashioned cake donut.
Cold butter
Cold cubed butter helps the streusel keep both fine crumbs and large buttery clusters instead of melting into the batter.
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.
- 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.
- Silk Original Unsweet
Butter sticks
Butter sticks
Use butter sticks for buttercream and fillings that need to hold their shape.
- 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 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 zest is rubbed into the sugar
Rubbing the zest into both sugars releases its fragrant oils before the wet ingredients go in. The mixture should smell distinctly lemony when you are done.
Why fresh raspberries are essential
Frozen raspberries release significantly more liquid as they thaw and bake, which can make this loaf wet and uneven. Firm fresh berries hold their shape better and bleed less.
Why the berries go in last
Adding the raspberries when the batter is almost combined limits the amount of folding needed. This protects the berries and helps prevent overmixing.
Why the pan should stay below three-quarters full
This is a generous batter. Leaving enough room lets the center rise and bake through without spilling over. I am conservative and stop just after two-thirds full, then bake any excess as muffins or mini loaves.
How to check for doneness
Use a toothpick, an instant-read thermometer, or preferably both. Insert them into the center cake portion rather than through a raspberry or the streusel seam. My photographed loaf reached about 210°F, and the tester came out with moist crumbs rather than wet batter.
The surface cannot tell you the center is done
A browned, set-looking top is not proof that the center has finished baking. Tent the loaf loosely with foil once the surface is sufficiently browned, then let the center continue baking until the tester or thermometer confirms it is done.
Choose the pan with care
I use a 9x5-inch Fat Daddio's anodized aluminum loaf pan and swear by this brand and material for an even bake. The pans are inexpensive and available on Amazon. A different pan material can change how quickly the edges brown and how long the center needs.
How it comes together
Small things that matter
Tips for the best loaf
Choose the firmest fresh raspberries you can find. They hold their shape better during baking and bleed less than fragile berries.
Do not use frozen raspberries. Their extra liquid can make the loaf wet and prevent it from baking evenly.
Keep the streusel refrigerated until you are ready to layer it, and preserve a mix of fine crumbs and larger buttery clusters.
Fold the raspberries gently and only until evenly distributed. Do not intentionally break them apart.
Stop filling the pan just after two-thirds full, and never go beyond three-quarters. Bake extra batter as muffins or mini loaves.
Check the loaf at 45 minutes and tent it loosely with foil if the streusel is sufficiently browned. A browned or set-looking surface does not mean the center is finished.
After tenting, avoid repeatedly opening the oven. Every check releases heat, prolongs the bake, and makes the process more frustrating.
Listen to your oven. Mine is smaller and bakes more quickly, but another oven or pan may need much closer to the full 90 minutes.
Before you slice
Texture and serving notes
Let the glaze set completely before slicing so it forms the crackly coating that makes the loaf taste like an old-fashioned donut.
Serve at room temperature for the softest crumb and the clearest lemon and raspberry flavor.
Keep it good

Recipe FAQ
Questions that come up
Can I use frozen raspberries?
I do not recommend it. Frozen raspberries contain significantly more liquid, which can make the loaf wet and interfere with an even bake. Use firm fresh raspberries for distinct fruit pockets with less bleeding.
Can I use lemon extract instead of lemon emulsion?
Yes. I like lemon emulsion because it gives the loaf a rounder lemon flavor and aroma, but lemon extract works perfectly well in the same amount.
Can I make this loaf with lime instead of lemon?
Yes. Swap the lemon zest, juice, and emulsion for their lime equivalents for a subtle but unique raspberry-lime variation.
What should I do with extra batter?
Do not overfill the loaf pan. I stop just after two-thirds full and never go beyond three-quarters. Divide any extra batter among lined muffin cups or mini loaf pans, add streusel and sanding sugar, and bake at 350°F (175°C). Begin checking muffins around 18 minutes and mini loaves shortly after that; they are done when the centers are set and a tester comes out without wet batter.
Can I use Greek yogurt?
Yes. Use 170 g plain unsweetened Greek yogurt and increase the milk to 160 g. The additional milk brings the thicker yogurt back to the consistency this batter needs.
Can I substitute sour cream for the yogurt?
Yes. Use 200 g full-fat sour cream in place of the yogurt, but check its consistency first. It should be thick rather than loose or pourable. If you are taking the non-dairy route, Forager Sour Cream is too thin for this substitution.
What loaf pan do you use?
I use a 9x5-inch Fat Daddio's anodized aluminum loaf pan. It is inexpensive, available on Amazon, and I swear by this brand and material for an even bake. Glass, dark nonstick metal, and silicone conduct heat differently, so use the toothpick and center temperature rather than relying on time alone.
Can I use dairy ingredients?
Yes. I test all of my recipes with non-dairy ingredients, but you can use the plain unsweetened yogurt, milk, and butter you have on hand while keeping the listed amounts and temperatures the same.
How do I know when the loaf is done?
Use a toothpick, an instant-read thermometer, or preferably both. My photographed loaf reached about 210°F in the center, and a tester inserted into the cake portion came out with moist crumbs rather than wet batter. Avoid a raspberry or the streusel seam. A browned, set-looking surface is not an indicator that the center is finished; tent it loosely with foil and keep baking. Once tented, do not repeatedly open the oven to check because the lost heat will prolong the bake.
Why don't you provide volume measurements?
I know cups feel familiar, but weight is the most reliable way to give you the same result I tested. Flour, sugar, yogurt, milk, and other primary ingredients can vary a surprising amount when scooped or poured, while grams keep the recipe's ratios accurate. A scale is also faster and means fewer dishes because many ingredients can be weighed directly into the bowls already used in the recipe instead of requiring a full set of measuring cups. I still use teaspoons and tablespoons for small quantities like leaveners, salt, spices, and flavorings, where they are the most practical choice.
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.
