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. This ensures easy removal of the bars after baking.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, nutmeg, and salt. This blend creates a flavorful base for your donut bars.
Step 3: Cream the Butter and Sugar
In a large bowl, beat the softened butter and sugar until light and fluffy.
1. Add the eggs one at a time.
2. Mix well after each addition.
3. Stir in the vanilla extract.
Step 4: Add the Buttermilk and Dry Ingredients
Alternate adding the flour mixture and buttermilk to the butter mixture:
1. Start with flour, then add buttermilk.
2. Repeat until all ingredients are combined.
3. Be careful not to overmix; aim for just combined.
Step 5: Bake the Donut Bars
Spread the batter evenly in the prepared pan and smooth out the top.
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:
1. Melt the butter until it turns golden brown and releases a nutty aroma — watch closely!
2. Remove from heat; whisk in powdered sugar, maple syrup, and vanilla bean paste.
3. Add milk gradually if needed for desired thickness.
Step 7: Glaze the Bars
Pour warm glaze over cooled bars, spreading it evenly across the surface. Let set for about 10–15 minutes before slicing into generous rectangles or smaller pieces as desired.
