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
For the Brown Butter Maple Vanilla Bean Glaze
- ½ cup unsalted butter
- 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)
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.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, nutmeg, and salt. Ensure there are no lumps so that your donut bars have a uniform texture.
Step 3: Cream the Butter and Sugar
In a large bowl, beat together the softened butter and granulated sugar until light and fluffy. This should take about 3-4 minutes. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract until fully integrated.
Step 4: Add the Buttermilk and Dry Ingredients
Alternately add the flour mixture and buttermilk to your butter mixture. Start with one-third of the flour mixture followed by half of the buttermilk. Repeat this process until all ingredients are combined without overmixing.
Step 5: Bake the Donut Bars
Spread the batter evenly into your prepared pan. Smooth out the top with a spatula. 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. Continue cooking until it turns golden brown and emits a nutty aroma—watch closely to prevent burning. Remove from heat and whisk in powdered sugar, maple syrup, and vanilla bean paste. If necessary, add milk to achieve desired consistency.
Step 7: Glaze the Bars
Pour warm glaze over cooled bars while spreading it evenly with a spatula. Let set for about 10-15 minutes before slicing into generous rectangles or smaller pieces as desired.
