How to Make Old-Fashioned Buttermilk Donut Bars

Ingredients:

2 ½ cups all-purpose flour
2 tsp baking powder
1 tsp baking soda
½ tsp ground nutmeg
1 tsp salt
½ cup unsalted butter, softened
¾ cup granulated sugar
2 large eggs
1 tsp vanilla extract
¾ cup buttermilk
½ cup unsalted butter (for glaze)
1 ½ cups powdered sugar
2 tbsp pure maple syrup
1 tsp vanilla bean paste (or vanilla extract)
1–2 tbsp milk (for thinning, as needed)

Directions:

Prepare the Oven and Pan
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper. I remember watching my grandmother carefully butter every corner of her pan, making sure nothing stuck. It’s worth the few extra moments.
Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, nutmeg, and salt. The nutmeg is key here — it’s what gives these old-fashioned buttermilk donut bars that classic donut-shop aroma.
Cream the Butter and Sugar
In a large bowl, beat the softened butter and sugar until light and fluffy. This step creates that tender, cakey texture. Add the eggs, one at a time, mixing well after each. Stir in the vanilla extract.
Add the Buttermilk and Dry Ingredients
Alternate adding the flour mixture and the buttermilk to the butter mixture, beginning and ending with the flour. Mix just until combined — don’t overmix, or your bars might turn out dense.
Bake the Donut Bars
Spread the batter evenly into the prepared pan and smooth the top. Bake for 22–25 minutes, or until a toothpick inserted in the center comes out clean. Let the bars cool completely before glazing.
Make the Brown Butter Maple Vanilla Bean Glaze
In a small saucepan, melt the butter over medium heat and continue cooking until it turns golden brown and smells nutty — watch it closely, as it can burn quickly. Remove from heat and whisk in the powdered sugar, maple syrup, and vanilla bean paste. Add a splash of milk if the glaze seems too thick.
Glaze the Bars
Pour the warm glaze over the cooled bars, spreading it evenly. Let the glaze set for about 10–15 minutes before slicing. I like to cut these into generous rectangles, just like my grandmother did, but you can cut them smaller if you’re serving a crowd.

How to Serve Old-Fashioned Buttermilk Donut Bars

These donut bars are best served fresh, slightly warm, and generously glazed. They are perfect with a cup of coffee or tea, making them a fantastic choice for brunch or an afternoon snack. You can also enjoy them plain if you want to keep it simple and let the rich flavors shine through. Feel free to sprinkle them with some additional powdered sugar for that extra touch of sweetness!

How to Store Old-Fashioned Buttermilk Donut Bars

If you have any leftovers (though I doubt you will!), you can store these donut bars in an airtight container at room temperature for up to three days. If you’d like to keep them longer, you can freeze them properly. Wrap the bars tightly in plastic wrap and then place them in a freezer bag; they can last up to three months in the freezer. To enjoy, simply thaw them at room temperature or warm them up in the microwave for a few seconds.

Tips to Make Old-Fashioned Buttermilk Donut Bars

Don’t Overmix: When combining the wet and dry ingredients, mix just until everything is combined to avoid dense bars.
Use Fresh Ingredients: Fresh baking powder and baking soda are essential for the right rise.
Keep an Eye on Butter: When browning the butter for the glaze, stay right next to it; it can go from perfect to burnt in no time.
Experiment with Toppings: Feel free to add sprinkles or nuts on top of the glaze for an extra flair!

Variation

You can customize these donut bars by adding mix-ins like chocolate chips, chopped nuts, or even flavored extracts such as almond or orange for a new twist on the classic recipe.

FAQs

1. Can I use regular milk instead of buttermilk?
Yes, if you don’t have buttermilk, you can make a substitute by adding 1 tablespoon of lemon juice or vinegar to a cup of milk and letting it sit for about 5-10 minutes.

2. How do I know when the donut bars are done baking?
A toothpick inserted into the center should come out clean, which is a great indicator that your bars are fully baked.

3. Can I make the glaze in advance?
While the glaze is best used fresh, you can make it a few hours ahead of time. Just warm it gently in the microwave before using, adding a little milk if it thickens up too much.

With these simple steps and tips, you’ll have homemade Old-Fashioned Buttermilk Donut Bars with Brown Butter Maple Vanilla Bean Glaze that are sure to impress everyone. Happy baking!
