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. Taking this extra moment ensures that your donut bars will come out perfectly without sticking, just like my grandmother would do!
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 here — it adds that classic donut-shop aroma that makes your kitchen smell heavenly.
Step 3: Cream the Butter and Sugar
In a large bowl, beat the softened butter and sugar until light and fluffy. This step is vital because it creates that tender, cakey texture we all love in donuts. Add the eggs one at a time, mixing well after each addition. Finally, stir in the vanilla extract to bring everything together.
Step 4: Add the Buttermilk and Dry Ingredients
Alternate adding the flour mixture and buttermilk to the butter mixture, starting and ending with flour. Mixing just until combined keeps your bars from being dense — we want them light and airy!
Step 5: Bake the Donut Bars
Spread the batter evenly into your prepared pan and smooth out the top. Bake for 22–25 minutes or until a toothpick comes out clean from the center. Allowing them to cool completely before glazing is key; it helps set that delicious topping.
Step 6: Make the Brown Butter Maple Vanilla Bean Glaze
In a small saucepan over medium heat, melt half a cup of unsalted butter until it turns golden brown and gives off 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 it’s too thick, add milk gradually until you reach your desired consistency.
Step 7: Glaze the Bars
Pour that gorgeous warm glaze over your cooled donut bars while spreading it evenly. Let it set for about 10–15 minutes before slicing into generous rectangles — just like Grandma used to do!
And there you have it! A delightful way to create memories sweetened by nostalgia with every delicious bite of these Old-Fashioned Buttermilk Donut Bars with Brown Butter Maple Vanilla Bean Glaze. Enjoy every moment!
Pro Tips for Making Old-Fashioned Buttermilk Donut Bars with Brown Butter Maple Vanilla Bean Glaze
Creating the perfect batch of donut bars is all about the little details! Here are some tips to ensure your baking experience is a delicious success.
- Measure Flour Accurately: Use the spoon and level method to measure your flour. This helps avoid dense bars caused by too much flour, ensuring a light and tender texture.
- Don’t Overmix: Once you combine the wet and dry ingredients, mix just until combined. Overmixing can lead to tough donut bars, so treat your batter gently!
- Use Fresh Ingredients: Check the expiration dates on your baking powder and baking soda. Fresh leavening agents make a big difference in how well your donut bars rise and their overall texture.
- Cool Completely Before Glazing: Allowing your donut bars to cool completely before adding the glaze prevents it from melting away and ensures a beautiful finish. Plus, it helps that glaze adhere better!
- Customize Your Glaze Thickness: Adjust the amount of milk in your glaze to achieve your desired consistency. A thicker glaze will sit beautifully on top, while a thinner one will create a lovely drip effect.

Side Dishes
