Pistachio Donut Loaf
Be the first to reviewThis pistachio donut loaf disappeared every time I tested it. The thin vanilla glaze settles over buttery roasted pistachio crumble, then cracks when you slice in.
Inside, the center stays extra moist, almost like the middle of a fresh cake donut, with pistachio tucked through the crumb.
If you love pistachio, this is such a good one to make. It is easy, cozy, and already one of my favorites.

The Loaf I Made Three Times in One Week
After testing this pistachio donut loaf, I made it three times in the same week. One batch went to work with my husband and was completely gone by 10 a.m., which felt like all the confirmation I needed.
Pistachio always tastes sophisticated to me, and apparently my brain interprets sophisticated as permission to keep eating long after I would normally stop. The delicate, nutty flavor is especially good once the loaf is completely chilled and the glaze has set into that thin crackly shell.
Finish it with a little Maldon salt and suddenly it feels like a $12 bakery loaf - except you have the entire thing at home, which is both wonderful and slightly dangerous.
Ingredient notes
Key ingredients
Roasted, lightly salted pistachios
Roasted pistachios bring deeper flavor than raw pistachios. I prefer them lightly salted, but unsalted pistachios work just fine. Coarsely grinding them lets the flavor move through the batter while still leaving tiny pistachio pieces in the crumb.
Plain unsweetened yogurt
Yogurt gives the loaf moisture, body, and tenderness.
Milk
Milk loosens the batter and makes the vanilla glaze pourable.
Cold butter
Use cold butter sticks for the streusel instead of a tub-style spread. Keep the streusel chilled while you make the batter so the clusters hold their shape.
Almond extract and nutmeg
The almond extract is optional, but it makes the pistachio taste rounder. The nutmeg is small on purpose; it gives a quiet old-fashioned donut note without taking over.
Coarse sanding sugar
A light layer of coarse sanding sugar goes over the streusel just before baking. 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.
Brands I used for this recipe
These are preferences, not requirements. If you choose the non-dairy route, these are the products I test with. Dairy equivalents can be used at the same listed amounts and temperatures.

If This Happens
The streusel feels soft or greasy
Return it to the refrigerator before layering the loaf. Cold butter helps the pistachio streusel hold its clusters instead of melting into the batter.
The batter is above the two-thirds mark
Stop adding batter. Leaving room at the top helps this rich loaf rise without overflowing and gives the center a better chance to bake through.
The top is brown but the center is not ready
Tent the loaf loosely with foil and continue baking. Test the cake portion beside the middle streusel seam so that layer does not give you a misleading result.
It is taking a long time to bake
Every oven is different, and this deep loaf may need close to 90 minutes. Make sure to keep the oven door closed instead of checking frequently. If the tester has a thick, paste-like residue, check again in 3-5 minutes. If it looks like wet unbaked batter, wait 7-10 minutes.
The glaze is disappearing into the loaf
Let the loaf cool on the wire rack until warm but no longer hot before glazing. A hot loaf can melt the glaze instead of letting it form a thin coating.
Before you slice
Texture and serving notes
Serve the loaf warm for the softest crumb, or chill it fully for a denser, more traditional cake-donut bite.
Keep it good
Storage
Fridge
Store covered in the refrigerator for up to 4 days.
Freezer
Freeze individual slices for up to 2 months.
Serve

Recipe FAQ
Questions that come up
Can I use unsalted pistachios in pistachio donut loaf?
Yes. Unsalted pistachios work just fine. If you would like a little more salt, sprinkle a small amount of Maldon sea salt over the loaf after baking.
Why should I only fill the loaf pan 2/3 full?
Donut loaves are rich, soft, and high-rising. Filling the pan only 2/3 full gives the batter room to lift without overflowing and helps the center bake through cleanly.
How do I know when pistachio donut loaf is done baking?
Use the tester first: a toothpick inserted into the cake portion should come out with moist crumbs, not wet batter. The center should no longer jiggle and the streusel should be golden. Temperature is a helpful baseline, usually around 205-210°F (96-99°C) in the cake portion.
Can pistachio donut loaf be made ahead?
Yes. Store it covered in the refrigerator for up to 4 days, or freeze individual slices for up to 2 months. Let chilled slices sit at room temperature for 20-30 minutes if you want a softer bite.
Will it turn out the same if I use volume measurements?
Often, yes - but not always. Flour and other ingredients can weigh differently from one cup to the next depending on how they are filled or packed, and even humidity can make a difference. That is why I recommend using a scale when you can. These loaves are easy to make, but their ratios are precise. Baking ingredients are expensive, and there is nothing more frustrating than a loaf that does not turn out as expected. Volume measurements are included for convenience, but weighing gives you the closest match to the recipe I tested.
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.

Measurement note
For the closest match to the recipe I tested, use grams. Volume measurements are included for convenience, but cups can vary, so I cannot guarantee the exact same result when measuring by volume.

Pan used
I personally prefer a light-colored aluminum pan for these loaves. Here is the one I use. Not sponsored. I don't earn a commission from this link.
Glass holds heat longer, so the edges can overbake before the center is done. If you use glass, loosely tent the loaf with foil early, as soon as the top starts to brown. The foil helps protect the top, but it does not stop the sides or bottom from baking too quickly.
Removing the parchment
Carefully lift the loaf onto a wire rack and remove the parchment from underneath. I carefully flip the loaf onto its side, then turn it upside down onto my forearm so I can peel away the parchment without damaging the loaf.
Instructions
- 1Preheat the oven to 350°F. Grease and fully line a 9x5-inch loaf pan with parchment paper.
- 2Make the streusel. In a medium bowl, whisk together the flour, granulated sugar, brown sugar, and salt. Add the cold butter and vanilla bean paste. Work together until crumbly with a mix of small crumbs and larger clusters.
- 3Fold the coarsely ground pistachios into the streusel, then refrigerate while preparing the batter.
- 4In a large bowl, whisk together the granulated sugar, oil, yogurt, milk, vanilla bean paste, almond extract, if using, and apple cider vinegar until completely smooth.
- 5Add the flour, coarsely ground pistachios, cornstarch, baking powder, baking soda, salt, and nutmeg. Whisk just until combined and no dry streaks remain.
- 6Spread just under half of the batter into the prepared loaf pan, keeping the pan no more than 2/3 full once all layers are added.
- 7Sprinkle half of the chilled streusel evenly over the batter.
- 8Carefully spread the remaining batter over the streusel until completely covered.
- 9Top evenly with the remaining streusel, leaving plenty of large clusters.
- 10Sprinkle the top lightly and evenly with coarse sanding sugar just before baking.
- 11Bake for 55-90 minutes, checking around 35 minutes and covering loosely with foil if the streusel is browning quickly.

Before you take the loaf out
Baking time is a guide, not a deadline.
Check the center: Insert a skewer or toothpick into the cake in the center, avoiding the streusel layer.
Ready to come out: The center no longer jiggles and the tester comes out clean or with moist crumbs. No wet batter.
Keep baking: Thick, paste-like batter: bake 3-5 minutes more. Wet batter: bake 7-10 minutes more. Then test the center again.
The 205-210°F (96-99°C) range is an extra check. Batter on the tester still means keep baking, even at that temperature.
An underbaked center can collapse as the loaf cools.
- 13Cool in the pan for 20 minutes, then carefully lift the loaf onto a wire rack. Let it cool until warm but no longer hot.
- 14Whisk together the powdered sugar, milk, vanilla bean paste, and salt until smooth and pourable.
- 15Once the loaf is on the wire rack and feels warm but no longer hot, spread the glaze evenly over the top and sides.
- 16Immediately sprinkle the chopped pistachios evenly over the wet glaze.
- 17Let the glaze set before slicing.
