What Is a Buttermilk Bar Donut?
The buttermilk bar donut is a classic American creation, typically found in old-fashioned bakeries and donut shops.

- Shape: Rectangular, often with a rough, golden-brown top.
- Texture: Crisp, craggy exterior with a soft, moist crumb.
- Flavor: Classic vanilla and buttermilk, occasionally glazed for extra sweetness.
- Type: Cake donut (leavened with baking powder rather than yeast).

Step-by-Step Buttermilk Bar Donut Recipe
Ingredients List (For 16–18 bars)
| Ingredient | Amount |
|---|---|
| All-purpose flour | 3 cups (360g) |
| Baking powder | 2 tsp |
| Baking soda | 1/2 tsp |
| Salt | 1 tsp |
| Granulated sugar | 1 cup (200g) |
| Eggs | 2 large |
| Buttermilk | 3/4 cup (180ml) |
| Unsalted butter, melted | 1/3 cup (76g) |
| Vanilla extract | 2 tsp |
| Vegetable or canola oil (for frying) | About 6 cups |
Instructions
- Prepare Dry Ingredients: In a large bowl, whisk together flour, baking powder, baking soda, and salt.
- Mix Wet Ingredients: In another bowl, blend sugar, eggs, buttermilk, melted butter, and vanilla until smooth.
- Combine: Add the wet ingredients to the dry, stirring gently just until a thick, sticky dough forms. Do not overmix; dough should appear rough.
- Shape Dough: Lightly dust your work surface with flour. Transfer dough and gently pat into a 1-inch thick rectangle. Cut into bars measuring approximately 1×4 inches, using a bench scraper or knife.
- Heat Oil: Pour oil into your pot to a depth of 2 inches. Heat to 350°F (175°C) and monitor closely.
- Fry Donuts: Carefully lower dough bars into hot oil, frying a few at a time to avoid overcrowding. Fry 2–3 minutes per side, turning once, until lightly golden and craggy.
- Drain and Cool: Remove donuts with a slotted spoon and set on wire racks lined with paper towels.
- Glaze or Dust: While still warm, dip donuts in glaze or sprinkle with powdered sugar.
Donut Glazes: Classic Vanilla, Chocolate, and Citrus
Glazing transforms buttermilk bar donuts, adding luster and flavor while accentuating their craggy surface. Below are classic options, each easy to prepare and customize.
Classic Vanilla Glaze
- 2 cups powdered sugar
- 1/4 cup milk (plus more for thinning)
- 2 tsp vanilla extract
Whisk together until smooth. Dip warm donuts, letting excess drip off before placing on wire racks.
Chocolate Glaze
- 1 cup semisweet chocolate chips
- 2 tbsp unsalted butter
- 2 tbsp corn syrup
- 1–2 tbsp milk
Melt chocolate chips and butter together. Stir in corn syrup and milk until glossy and pourable.
Citrus Glaze
- 2 cups powdered sugar
- Zest of 1 lemon or orange
- 2–3 tbsp lemon/orange juice
Whisk until combined for a tart, fragrant finish.
Secrets to Craggy, Bakery-Style Donuts
- Do not overmix: Minimal stirring preserves a rough, craggy texture.
- Cool dough briefly: Chilling for 15–20 minutes makes shaping easier but is not required.
- Use a bench scraper: This tool creates clean, straight edges and maximizes the crispy top.
- Monitor oil temperature: Oil that is too hot burns the exterior; too cool results in greasy donuts.
- Work in batches: Overcrowding lowers oil temperature and affects texture.
Troubleshooting & Pro Tips
- Greasy Donuts: Oil too cool (<350°F). Allow oil to reheat between batches.
- Dense Crumb: Overmixed dough or expired baking powder.
- Flat Donuts: Dough too warm or too thin; use a light hand when patting and cutting bars.
- Spreading in Oil: Under-mixed dough or shaped when too soft. Chill dough or add a dusting of flour.
- Dry texture: Dough left uncovered too long or oil too hot. Fry promptly after shaping.
Serving and Storing Buttermilk Bar Donuts
- Serve Fresh: Buttermilk bars are best enjoyed within hours of frying for optimal crunch and flavor.
- Storing: If necessary, store in an airtight container for up to 2 days. Texture will soften but flavor remains excellent.
- Reheating: Warm gently in the oven at 300°F for 5 minutes. Avoid microwaving, which toughens the crumb.
Variations & Customizations
- Spiced Donuts: Add 1/2 teaspoon cinnamon or nutmeg to the dry mix.
- Maple Glaze: Substitute maple syrup for part of the milk in the vanilla glaze.
- Nutty Topping: Sprinkle chopped toasted nuts after glazing.
- Mini Bars: Cut smaller pieces for bite-size treats; adjust frying time accordingly.
- Chocolate-Chip Bars: Fold in 1/2 cup mini chocolate chips before shaping.
Frequently Asked Questions (FAQs)
Q: Do I really need buttermilk for these donuts?
A: Yes, buttermilk provides the distinctive tang and tenderness. If unavailable, use 3/4 cup milk mixed with 2 teaspoons lemon juice or vinegar. Let rest 5 minutes before using.
Q: Can the dough be prepared ahead?
A: Dough can be prepared and refrigerated up to 1 day in advance. Shape and fry cold dough straight from the fridge for easier handling.
Q: Is it possible to bake instead of fry buttermilk bars?
A: Baking will yield a softer, cake-like bar lacking the signature craggy exterior. Frying is essential for authentic texture and flavor.
Q: Can I freeze the donuts?
A: Buttermilk bars freeze well. Cool completely, wrap tightly, and freeze up to 1 month. Reheat from frozen in a 325°F oven for 8–10 minutes.
Q: Why are buttermilk bars sometimes called “craggy donuts”?
A: Their rough, uneven tops are a result of the unique dough and frying method, creating the craggy appearance that sets them apart from smooth-glazed donuts.
