Buttermilk Bar Doughnut

If you’ve ever had a buttermilk bar doughnut, you know it’s something special. Unlike fluffy yeast doughnuts, buttermilk bars have a dense yet tender crumb, a slightly crisp exterior, and deep ridges that soak up a luscious glaze. These doughnuts are old-fashioned bakery favorites, with a hint of tanginess from buttermilk and a subtle vanilla sweetness that makes them absolutely addictive.

What makes these doughnuts unique? They don’t rise like yeast doughnuts. Instead, they rely on baking powder for leavening, giving them a craggy, rustic texture. And that glaze? It seeps into every crevice, creating a melt-in-your-mouth experience. These homemade buttermilk bars are surprisingly easy to make and taste even better than your favorite doughnut shop’s version!

Ingredients for Buttermilk Bar Doughnuts

For the Doughnuts:

2 ¾ cups all-purpose flour
2 teaspoons baking powder
½ teaspoon baking soda
½ teaspoon salt
½ teaspoon nutmeg (optional, for a classic flavor)
½ cup granulated sugar
2 tablespoons unsalted butter, softened
2 large egg yolks
1 teaspoon vanilla extract
¾ cup buttermilk
Vegetable oil for frying

For the Vanilla Glaze:

2 cups powdered sugar
¼ cup whole milk or heavy cream
1 teaspoon vanilla extract
Pinch of salt

Step-by-Step Instructions for Buttermilk Bar Doughnuts

Step 1: Prepare the Dough

In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and nutmeg.
In a separate large bowl, cream together the sugar and softened butter until combined.
Add the egg yolks and vanilla extract, mixing until smooth.
Alternately add the dry ingredients and buttermilk, starting and ending with the dry ingredients. Mix until a thick dough forms—it will be slightly sticky but firm.

Step 2: Chill the Dough

Wrap the dough in plastic wrap and refrigerate for at least 1 hour. This firms up the dough, making it easier to handle and helping the doughnuts hold their shape while frying.

Step 3: Shape the Doughnuts

Lightly flour a clean surface and roll out the dough to ½-inch thickness.
Using a sharp knife, cut the dough into rectangles (about 4 inches long and 1 ½ inches wide).
Lightly score a line down the center of each doughnut—this helps create the signature cracks while frying.

Step 4: Heat the Oil for Frying

In a large heavy-bottomed pot or deep fryer, heat about 3 inches of vegetable oil to 350°F (175°C).
Use a thermometer to ensure the oil stays at the right temperature—too hot, and the outside will burn before the inside cooks; too cool, and they’ll absorb too much oil.

Step 5: Fry the Doughnuts

Carefully lower 2-3 doughnuts into the hot oil, being careful not to overcrowd the pan.
Fry for 2-3 minutes per side, flipping once, until deep golden brown.
Remove with a slotted spoon and drain on a wire rack over a paper towel-lined tray.

Step 6: Make the Glaze

In a medium bowl, whisk together the powdered sugar, milk (or cream), vanilla extract, and a pinch of salt until smooth.
The glaze should be thin enough to drizzle but thick enough to coat the doughnuts.

Step 7: Glaze the Doughnuts

While the doughnuts are still slightly warm, dip each one into the glaze, ensuring it coats all the nooks and crannies.
Let the excess glaze drip off, then place the doughnuts back on the wire rack to set.

Step 8: Enjoy!

Let the glaze set for about 10 minutes, then dig in! These are best enjoyed fresh, while the glaze is slightly crisp and the inside is tender.

Ingredient Background

Buttermilk: The Secret to a Tender Doughnut

Buttermilk is the key ingredient that gives these doughnuts their moist, soft texture and subtle tangy flavor. The acidity in buttermilk reacts with the baking soda and baking powder, helping the dough rise and creating that classic old-fashioned crumb. If you don’t have buttermilk, you can easily make a substitute by mixing ¾ cup of milk with 1 tablespoon of lemon juice or vinegar and letting it sit for 5 minutes.

Egg Yolks: The Richness Factor

Using egg yolks instead of whole eggs results in a richer, denser dough, which is exactly what you want for a buttermilk bar doughnut. The yolks also add flavor, color, and structure to the dough.

Nutmeg: The Classic Doughnut Spice

A small amount of nutmeg is what gives buttermilk bars (and many classic doughnuts) their signature old-fashioned flavor. It’s subtle but makes a noticeable difference in bringing out the dough’s richness.

Technique Tips for Perfect Buttermilk Bar Doughnuts

1. Chilling the Dough is Essential

The dough for buttermilk bars is softer than yeast dough, so chilling it for at least 1 hour makes it easier to handle and shape. If the dough is too soft when rolling, pop it back in the fridge for another 15-20 minutes before cutting.

2. Getting the Signature Cracks and Crevices

To get that beautiful, rustic cracked top, lightly score a line down the center of each doughnut with a knife before frying. As the doughnuts cook, they naturally expand along the line, creating deep crevices for the glaze to settle into.

3. Maintaining the Right Frying Temperature

The ideal oil temperature is 350°F (175°C).
If the oil is too hot, the outside will brown too quickly while the inside remains raw.
If the oil is too cool, the doughnuts will absorb too much oil and become greasy.
Use a candy thermometer to monitor the temperature, adjusting the heat as needed between batches.

Alternative Variations

1. Chocolate Buttermilk Bar Doughnuts

For a chocolate version, swap ¼ cup of flour for cocoa powder and add ½ teaspoon of espresso powder to intensify the chocolate flavor.

2. Cinnamon Sugar-Coated Doughnuts

Instead of glazing, roll the warm doughnuts in a mix of ½ cup granulated sugar and 1 teaspoon cinnamon for a classic cinnamon-sugar coating.

3. Maple Glazed Buttermilk Bars

For a maple-flavored twist, replace the vanilla extract in the glaze with 1 teaspoon of maple extract and add a drizzle of maple syrup for extra richness.

Freezing and Storing Buttermilk Bar Doughnuts

1. Storing Leftovers

Buttermilk bar doughnuts are best enjoyed fresh, but if you have leftovers:

Store in an airtight container at room temperature for up to 2 days.
If stacking, place parchment paper between layers to prevent sticking.

2. Reheating for the Best Texture

Microwave for 10-15 seconds to slightly soften them.
For extra crispiness, warm them in a 350°F (175°C) oven for 5 minutes.

3. Freezing for Longer Storage

Let the doughnuts cool completely before freezing.
Wrap each doughnut individually in plastic wrap, then place in a zip-top freezer bag.
Freeze for up to 2 months.
Thaw at room temperature and refresh in a warm oven before serving.

Healthier Twist Ideas

1. Baked Buttermilk Bars Instead of Fried

For a lighter option, bake the doughnuts instead of frying:

Preheat oven to 375°F (190°C).
Shape the dough into bars and place on a parchment-lined baking sheet.
Brush lightly with melted butter.
Bake for 12-15 minutes, then glaze while warm.

2. Reduce the Sugar

Cut the sugar in the dough by ¼ cup to make them slightly less sweet.
You can also use honey or maple syrup instead of granulated sugar for a natural alternative.

3. Swap for Whole Wheat Flour

Use 50% whole wheat flour and 50% all-purpose flour for extra fiber and a nuttier flavor.

Serving Suggestions for Events

1. Brunch Party Favorite

Serve these alongside fresh fruit, scrambled eggs, and coffee for the ultimate brunch spread.

2. Holiday Treats

These doughnuts make a great holiday morning treat! Serve them with spiced hot chocolate or chai tea for a festive twist.

3. Dessert with Ice Cream

For an indulgent dessert, serve a warm buttermilk bar with a scoop of vanilla bean ice cream and drizzle with caramel or chocolate sauce.

Frequently Asked Questions (FAQs)

1. Can I make the dough ahead of time?

Yes! You can refrigerate the dough overnight and fry fresh in the morning. Just let it sit at room temperature for 10-15 minutes before rolling out.

2. Why didn’t my doughnuts get the signature cracks?

This happens if the oil temperature is too low or the dough is overmixed. Try scoring a deeper center line and ensuring the oil stays at 350°F (175°C).

3. Can I make mini versions?

Absolutely! Cut smaller 2-inch rectangles and fry for 1-2 minutes per side for bite-sized buttermilk bars.

4. Why did my doughnuts turn out greasy?

The oil may have been too cold.
The dough may have absorbed too much oil if not drained properly after frying.
Make sure to fry in small batches to keep the oil temperature stable.

5. Can I use a deep fryer instead of a pan?

Yes! A deep fryer ensures an even cooking temperature. Just set it to 350°F (175°C) and fry as directed.
