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)
- 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 to prevent sticking.
- Mix the Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, nutmeg, and salt. The nutmeg contributes a classic donut-shop aroma.
- Cream the Butter and Sugar: In a large bowl, beat the softened butter and granulated sugar until light and fluffy. Then, add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
- Add the Buttermilk and Dry Ingredients: Alternate adding the flour mixture and buttermilk to the butter mixture, starting and ending with the flour. Mix until just combined to avoid dense bars.
- Bake the Donut Bars: Spread the batter evenly in the prepared pan and smooth the top. Bake for 22–25 minutes or until a toothpick inserted into the center comes out clean. Allow bars to cool completely before glazing.
- Make the Brown Butter Maple Vanilla Bean Glaze: In a small saucepan over medium heat, melt the butter, cooking it until it turns golden brown and emits a nutty aroma, careful not to burn it. Remove from heat and whisk in powdered sugar, maple syrup, and vanilla bean paste. Add milk to adjust the glaze consistency if needed.
- Glaze the Bars: Pour the glaze over the cooled bars, spreading it evenly. Let the glaze set for 10–15 minutes before slicing into rectangles or desired shapes.
Notes
- Ensure butter is softened for easier creaming with sugar.
- Do not overmix the batter to keep the bars tender and avoid toughness.
- Watch the butter carefully when browning to prevent burning, which will affect the glaze flavor.
- You can substitute vanilla bean paste with vanilla extract, but paste provides a richer vanilla flavor.
- For a thinner glaze, add more milk gradually until the desired consistency is reached.
- Store leftover bars in an airtight container at room temperature for up to 3 days.
