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. I remember watching my grandmother carefully butter every corner of her pan, making sure nothing stuck. Taking this little extra step ensures that your delicious bars come out perfectly.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, nutmeg, and salt. The nutmeg is key here — it’s what gives these old-fashioned buttermilk donut bars that classic donut-shop aroma. Mixing these dry ingredients well ensures even distribution of flavors.
Step 3: Cream the Butter and Sugar
In a large bowl, beat the softened butter and sugar until light and fluffy. This step creates that tender, cakey texture we all love in donuts! Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract for that warm undertone.
Step 4: Add the Buttermilk and Dry Ingredients
Alternate adding the flour mixture and buttermilk to the butter mixture, starting and ending with flour. This method keeps your batter smooth without overmixing — which can lead to dense bars instead of fluffy ones!
Step 5: Bake the Donut Bars
Spread the batter evenly into your prepared pan and smooth out the top. Bake for about 22–25 minutes or until a toothpick inserted comes out clean. Letting them cool completely before glazing will help ensure that beautiful glaze sets nicely.
Step 6: Make the Brown Butter Maple Vanilla Bean Glaze
In a small saucepan over medium heat, melt half a cup of butter until it turns golden brown and smells nutty — keep an eye on it so it doesn’t burn! Remove from heat and whisk in powdered sugar, maple syrup, and vanilla bean paste until smooth. If your glaze seems too thick, add just enough milk to reach desired consistency.
Step 7: Glaze the Bars
Pour that warm glaze over your cooled bars, spreading it evenly across the top. Let them set for about 10–15 minutes before slicing into generous rectangles — just like how my grandmother used to do! You could opt for smaller pieces if you’re serving guests; either way will be delightful!
Pro Tips for Making Old-Fashioned Buttermilk Donut Bars with Brown Butter Maple Vanilla Bean Glaze
Baking these donut bars is a delightful experience, and with a few simple tips, you can elevate your results even further!
-
Use Fresh Ingredients: Always check the expiration dates on your baking powder and baking soda. Fresh leavening agents ensure that your donut bars rise perfectly and have that light, airy texture we all love.
-
Don’t Overmix the Batter: When combining your wet and dry ingredients, mix just until incorporated. Overmixing can lead to dense and tough bars instead of the tender crumb you’re aiming for.
-
Watch the Butter Closely: When making the brown butter glaze, keep an eye on it as it cooks. The difference between perfectly browned butter and burnt butter can be just a moment, so stir often and remove it from heat as soon as it turns golden and fragrant.
-
Cool Completely Before Glazing: Allow your baked bars to cool completely before adding the glaze. This helps the glaze set nicely and prevents it from sliding off into a puddle.
-
Experiment with Flavors: Feel free to add in some extras like chopped nuts or chocolate chips into the batter for added texture and flavor. Just remember to adjust your baking time if you do!
