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 for easy removal. Taking this extra step will help ensure your donut bars come out perfectly.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together:
* All-purpose flour
* Baking powder
* Baking soda
* Ground nutmeg
* Salt
The nutmeg is essential; it adds that classic aroma associated with old-fashioned donuts.
Step 3: Cream the Butter and Sugar
In a large bowl, beat together:
* Softened butter
* Granulated sugar
Mix until light and fluffy. Add eggs one at a time, ensuring they are well combined before adding the next. Finally, stir in the vanilla extract.
Step 4: Combine Wet and Dry Ingredients
Alternate adding the flour mixture and buttermilk to the creamed butter mixture. Start with flour and end with flour. Mix just until combined; avoid overmixing to keep your bars light.
Step 5: Bake the Donut Bars
Spread the batter evenly into the prepared pan. Bake for 22–25 minutes or until a toothpick 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:
* Unsalted butter
Cook until golden brown and fragrant. Remove from heat and whisk in:
* Powdered sugar
* Maple syrup
* Vanilla bean paste
Add milk as needed to achieve your desired glaze consistency.
Step 7: Glaze the Bars
Pour warm glaze over cooled bars, spreading it evenly. Let it set for about 10–15 minutes before slicing into generous rectangles or smaller pieces if serving many guests.
