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; it’s such an important step to ensure nothing sticks. Taking this time now will save you from frustration later!
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—it brings that warm aroma reminiscent of classic donut shops. This step sets up the foundation for our delicious bars.
Step 3: Cream the Butter and Sugar
In a large bowl, beat the softened butter and sugar until light and fluffy. This aeration gives our bars that tender cake-like texture we love. Add in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract—it’ll fill your kitchen with an inviting scent!
Step 4: Add the Buttermilk and Dry Ingredients
Now it’s time to combine! Alternate adding your dry mixture and buttermilk into the creamed mixture—start and end with flour. Be gentle; we don’t want to overmix or our bars might end up dense rather than fluffy.
Step 5: Bake the Donut Bars
Spread your batter evenly into the prepared pan and smooth out the top. Bake for about 22–25 minutes or until a toothpick inserted comes out clean. Let them cool completely before glazing; this patience will pay off when you taste that rich topping!
Step 6: Make the Brown Butter Maple Vanilla Bean Glaze
In a small saucepan over medium heat, melt your butter until it turns golden brown and smells nutty—keep an eye on it so it doesn’t burn! Remove from heat, then whisk in powdered sugar, maple syrup, and vanilla bean paste. If it’s too thick, add a splash of milk until you reach your desired consistency.
Step 7: Glaze the Bars
Pour that luscious warm glaze over your cooled bars, spreading it evenly across every inch. Allow it to set for about 10–15 minutes before slicing into generous rectangles—just like my grandmother used to do! If you’re serving a crowd, feel free to cut them smaller.
There you have it! A delicious way to create new memories while enjoying these Old-Fashioned Buttermilk Donut Bars with Brown Butter Maple Vanilla Bean Glaze. 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 a few simple tips can make the experience even more rewarding!
-
Use Fresh Ingredients: Always check the freshness of your baking powder, baking soda, and buttermilk. Fresh ingredients ensure your bars rise properly and have the best flavor.
-
Don’t Overmix the Batter: Mixing just until combined helps achieve that light, tender texture. Overmixing can lead to dense bars that aren’t as enjoyable.
-
Cool Completely Before Glazing: Allowing the bars to cool completely prevents the glaze from melting into the warm batter, ensuring a beautiful finish and a delicious bite.
-
Adjust Glaze Consistency: If your glaze seems too thick, add milk one tablespoon at a time until you reach your desired drizzling consistency. This ensures an even coating that perfectly complements the bars.
-
Experiment with Flavorings: Feel free to add spices like cinnamon or cardamom to the batter for an extra layer of flavor. It gives a personal touch and can evoke even more nostalgic memories!
