Pistachio Old-Fashioned Donut Bars

Pistachio Old-Fashioned Donut Bars

The texture of these is everything.

Crispy, craggy edges.
That classic split on top.
And a soft, light interior that’s not dense or cakey.

That’s exactly what these pistachio old-fashioned donut bars are.

They’re simple, but they feel elevated. The pistachio isn’t overpowering — it’s subtle, nutty, and pairs perfectly with the light glaze on top. And because they’re not overly sweet, they actually feel like something you’d get at a really good bakery.

The biggest thing with these is frying. Once you understand how to control the oil temperature, everything else is easy.

Why You’ll Love These

• Crispy, crackly old-fashioned donut texture
• Light, fluffy interior (not dense or cakey)
• Not overly sweet
• Unique pistachio flavor
• Bakery-style but made at home
• Small batch recipe

Ingredient Notes

Cake flour + all-purpose flour
This combination is what gives you structure without making the donuts heavy.

Buttermilk (or milk + vinegar)
This is key. The acidity reacts with baking soda to create a lighter, softer interior.

Ground pistachios
Blended finely so they incorporate into the dough and give flavor without ruining texture.

Pistachio sweet cream
Used in the glaze for an easy, smooth finish with a strong pistachio flavor.

How to Get That Old-Fashioned Texture

This is the part that makes or breaks the recipe.

• Don’t overmix the dough — it should be slightly lumpy
• Don’t make the dough perfectly smooth — rough edges = better cracks
• Cut a shallow slit down the center
• Keep your oil temperature steady
• Don’t overcrowd the pot

That’s what gives you those signature craggy edges.

Frying Tips (IMPORTANT)

Frying is the trickiest part, but once you get it, you’re set.

• Oil should be around 350–355°F
• I usually drop and flip donuts around 357–358°F
• The temperature will drop when you add and flip donuts — that’s normal
• The goal is to avoid big swings in temperature

Big swings = oily donuts.

If you have a countertop fryer, it makes this easier. If not, just stay focused and watch your thermometer.

Shape Notes

You don’t need a perfect rectangle.

In fact, you shouldn’t.

Use your hands to shape the dough slightly — rough edges and uneven patches actually help create better cracks when frying.

Glaze Notes

This glaze is intentionally simple.

You mix powdered sugar and milk first, then add the pistachio sweet cream, and adjust from there.

Add milk slowly — even one tablespoon can change the consistency a lot.

You’re looking for a glaze that:

• coats the donut
• doesn’t run off immediately
• sets softly

Make Ahead Option

If you want donuts for the morning — here’s how you do it!

Make the dough
Cover and refrigerate overnight

Next day:

• Let sit at room temp 10–15 minutes
• Roll, shape, and fry as directed

These are one of those recipes that feel a little more special than your average donut, but once you make them, you realize they’re actually pretty simple.

The texture is what makes them stand out. That crispy outside with the soft interior is exactly what you want from an old-fashioned donut.

And once you get comfortable frying them, you can play with so many variations.

But this pistachio version is a really good place to start.

• Sheet pan
• Blender or food processor
• Sharp knife

Method

 

Dough

1. In a bowl, whisk together 60 g (¼ cup + 1 tbsp) sugar, 1 egg + 1 egg yolk, 60 g (¼ cup) buttermilk, 20 g (1½ tbsp) melted butter, and 1 tsp vanilla until smooth.
2. In another bowl, whisk 120 g (1 cup) all-purpose flour, 50 g (⅓ cup + 1 tbsp) cake flour, 1¾ tsp baking powder, ¼ tsp baking soda, ½ tsp salt, a pinch of nutmeg, and 30–40 g ground pistachios.
3. Add the dry ingredients to the wet and gently fold until just combined. The dough should be slightly lumpy—do not overmix.
4. Cover and chill the dough for 30 minutes.

Oil Setup

1. Heat 3 inches of oil in a heavy pot
2. Start heating oil 15 minutes into the dough chill time so it reaches temperature as the dough finishes chilling

Shape

1. Lightly flour your surface and roll dough to ½–⅝ inch thick.
2. Use your hands to gently shape the dough — it does not need to be a perfect rectangle.
3. The dough will be sticky — do not add too much extra flour!
4. Slightly uneven edges and rough patches help create better cracks when frying.
5. Cut into 4-inch by 1.5-inch bars (6–8 total).
6. Use a knife to make a shallow slit down the center of each bar.

Make Glaze

1. In a bowl, whisk 120 g (1 cup) powdered sugar with 3 tbsp milk until smooth.
2. Add 3 tbsp pistachio sweet cream and whisk to combine.
3. Add more milk, 1 tbsp at a time, until the glaze becomes smooth, pourable, and thick enough to coat.
4. (You’ll typically use 4–5 tbsp total milk.)
5. Add a pinch of salt to balance sweetness.

Frying Instructions

1. Managing oil temperature is the most important part of this recipe.
2. When you drop donuts in → temp drops
3. When you flip → temp drops again
4. Large swings in temperature = oily donuts
5. A countertop fryer controls temperature best, but you can absolutely do this on the stove—you just need to stay focused.
6. Ideal working temp: 350–355°F
7. I usually drop and flip donuts around 357–358°F

Frying

1. Fry 3–4 donuts at a time, without overcrowding the pot.
2. First side: fry 2–2½ minutes, until cracks form and edges look jagged.
3. Flip and fry another ~2 minutes, until deep golden brown.
4. Remove to a wire rack set over a sheet pan.
5. Let cool 8–10 minutes before glazing.

Assemble

1. Dip the tops of the donuts into the glaze.
2. Immediately sprinkle with chopped pistachios.
3. Let set for 5–10 minutes before serving.

Notes

• Do not overmix the dough—this keeps the crumb light.
• Oil temperature control is key to preventing oily donuts.
• Slightly rough dough creates better cracks—don’t over-smooth it.
• The shallow center slit helps create the classic old-fashioned texture.
• Add milk to the glaze gradually—it changes quickly.

Storage

• Best eaten fresh
• Store at room temp up to 1 day
• Reheat 5–8 seconds before serving

Make Ahead Instructions 

• Make the dough
• Cover and refrigerate overnight

Next day:

• Let sit at room temp 10–15 minutes
• Roll, shape, and fry as directed
