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) and grease a 9×13-inch baking pan or line it with parchment paper. Remember how my grandmother always took her time buttering every corner? This little step ensures nothing sticks and makes cleanup easier!
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, nutmeg, and salt. The nutmeg is essential here—it gives these donut bars that classic donut-shop aroma that will have everyone flocking to the kitchen!
Step 3: Cream the Butter and Sugar
In a large bowl, beat the softened butter and granulated sugar until light and fluffy. This step creates that tender texture we all love in baked goods! Add the eggs one at a time, mixing well after each addition. Finally, stir in the vanilla extract for that lovely hint of flavor.
Step 4: Add the Buttermilk and Dry Ingredients
Now it’s time to bring it all together! Alternate adding the dry mixture and buttermilk into your butter mixture—start and end with flour. Be careful not to overmix; we want these bars light and airy!
Step 5: Bake the Donut Bars
Spread your batter evenly into the prepared pan and smooth out the top. Pop them in the oven for about 22–25 minutes or until a toothpick comes out clean when inserted into the center. Let them cool completely before glazing—this is crucial so that our delicious glaze doesn’t melt away!
Step 6: Make the Brown Butter Maple Vanilla Bean Glaze
In a small saucepan over medium heat, melt your butter until it’s golden brown and smells nutty—keep an eye on it since it can burn quickly! Once ready, remove from heat and whisk in powdered sugar, maple syrup, and vanilla bean paste. If it’s too thick, add some milk until you reach your desired consistency.
Step 7: Glaze the Bars
Pour that warm glaze over your cooled bars, spreading it evenly across the top. Let it set for about 10–15 minutes before slicing into generous rectangles—just like my grandmother used to do! If you’re serving guests, feel free to cut them smaller so everyone can enjoy a piece.
Now you’re ready to share these delightful old-fashioned buttermilk donut bars with those you love—or keep them all to yourself! Enjoy every bite!
Pro Tips for Making Old-Fashioned Buttermilk Donut Bars with Brown Butter Maple Vanilla Bean Glaze
Baking these delightful donut bars is a joy, and with a few pro tips, you can ensure they turn out perfectly every time!
-
Measure Flour Correctly: Spoon the flour into your measuring cup and level it off with a knife. This prevents packing too much flour, which can make your bars dense rather than light and fluffy.
-
Use Room Temperature Ingredients: Make sure your butter, eggs, and buttermilk are at room temperature before you start mixing. This helps them blend more easily and creates a smoother batter.
-
Don’t Overmix the Batter: Mix just until everything is combined. Overmixing activates the gluten in the flour, leading to tough bars instead of tender ones.
-
Cool Completely Before Glazing: Allow the bars to cool fully before pouring on the glaze. This ensures that the glaze stays glossy and doesn’t melt into the warm batter.
-
Adjust Glaze Consistency: If your glaze seems too thick, add milk one tablespoon at a time until you reach your desired consistency. A thinner glaze will create a beautiful drip effect over the bars!
