Ingredients
For the Donut Bars
- 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

How to Make Old-Fashioned Buttermilk Donut Bars with Brown Butter Maple Vanilla Bean Glaze
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper. Taking the time to properly prepare your pan will prevent sticking.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, nutmeg, and salt. The nutmeg is crucial for creating that beloved donut shop aroma.
Step 3: Cream the Butter and Sugar
In a large bowl, beat the softened butter and sugar until light and fluffy. This step is vital for achieving that perfect cakey texture. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
Step 4: Add the Buttermilk and Dry Ingredients
Alternate adding the flour mixture and buttermilk to the butter mixture. Start and end with flour. Mix until just combined; overmixing can lead to dense bars.
Step 5: Bake the Donut Bars
Spread the batter evenly in your prepared pan. Bake for 22–25 minutes or until a toothpick inserted in the center comes out clean. Allow cooling completely before glazing.
Step 6: Make the Brown Butter Maple Vanilla Bean Glaze
In a small saucepan over medium heat, melt the butter until it turns golden brown with a nutty aroma—watch carefully to prevent burning! Remove from heat and whisk in powdered sugar, maple syrup, and vanilla bean paste. If necessary, add a splash of milk to reach desired thickness.
Step 7: Glaze the Bars
Pour warm glaze over cooled bars evenly. Let it set for about 10–15 minutes before slicing into generous rectangles or smaller pieces as preferred. Enjoy every bite!

How to Perfect Old-Fashioned Buttermilk Donut Bars with Brown Butter Maple Vanilla Bean Glaze
Perfecting your old-fashioned buttermilk donut bars requires attention to detail and a few helpful tips. Here’s how you can ensure they turn out wonderfully every time.
-
Use Fresh Ingredients – Ensure your baking powder and baking soda are fresh for optimal rise and texture in your donuts.

Check Doneness Early – Start checking for doneness around 20 minutes of baking time. Ovens can vary in temperature, so it’s best to be cautious.

Cool Completely Before Glazing – Allowing the bars to cool completely ensures that the glaze adheres properly rather than melting off into puddles.

Common Mistakes to Avoid
Baking can be tricky, and avoiding common mistakes will ensure your Old-Fashioned Buttermilk Donut Bars with Brown Butter Maple Vanilla Bean Glaze turn out perfectly.
-
Boldly Overmixing the Batter: When you combine the wet and dry ingredients, mix just until incorporated. Overmixing can lead to dense donut bars instead of light and fluffy ones.
-
Ignoring the Oven Temperature: Always preheat your oven to 350°F (175°C) before baking. An unprepared oven can result in uneven baking and affect the texture of your donut bars.
-
Not Using Fresh Ingredients: Check your baking powder and baking soda for freshness. Expired leavening agents can prevent your donut bars from rising properly.
-
Skipping the Cooling Time: Allow the bars to cool completely before glazing. If you glaze them while warm, the icing may melt away, ruining that beautiful finish.
-
Measuring Incorrectly: Be precise when measuring flour and sugar. Too much or too little can drastically change the outcome of your Old-Fashioned Buttermilk Donut Bars.
