- 2 tsp baking powder

- ½ cup unsalted butter, softened
- ¾ cup granulated sugar
- 2 large eggs

How to Make Old-Fashioned Buttermilk Donut Bars with Brown Butter Maple Vanilla Bean Glaze
Step 1: 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. Take your time to ensure every corner is well-greased to 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 as it gives these donut bars their signature aroma.
Step 3: Cream the Butter and Sugar
In a large bowl, beat the softened butter and sugar together until light and fluffy. This process ensures your donut bars have a tender texture. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract until fully combined.
Step 4: Add the Buttermilk and Dry Ingredients
Slowly alternate adding the flour mixture and buttermilk into the butter mixture, starting with flour and ending with flour. Mix just until combined; avoid overmixing to keep your bars light.
Step 5: Bake the Donut Bars
Spread the batter evenly into your prepared pan, smoothing out the top. Bake for 22–25 minutes or until a toothpick inserted into the center comes out clean. Allow them to cool 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 and emits a nutty aroma—keep an eye on it so it doesn’t burn! Remove from heat and whisk in powdered sugar, maple syrup, and vanilla bean paste. If necessary, add milk to reach your desired glaze consistency.
Step 7: Glaze the Bars
Pour warm glaze over cooled bars, spreading it evenly with a spatula. Let it set for about 10–15 minutes before cutting into generous rectangles or smaller pieces if serving a crowd. Enjoy every bite of these delightful old-fashioned buttermilk donut bars!
