Essential Ingredients
Here’s what you’ll need to make this delicious dish:
All-Purpose Flour: Use high-quality flour for the best texture; it helps create the perfect density in your donut bars.
Granulated Sugar: This adds sweetness and contributes to that lovely golden color we all adore in donuts.
Baking Powder: Essential for leavening; it gives your donut bars that fluffy rise we crave.
Salt: Just a pinch enhances flavors and balances out the sweetness in your donut bars.
Buttermilk: This ingredient makes your donut bars moist and tender; if you don’t have it, mix milk with vinegar as a substitute.
Eggs: Use large eggs to bind everything together and add richness to your donut bars.
Unsalted Butter: Make sure it’s softened; this adds flavor and moisture to your batter.
Maple Syrup: Pure maple syrup brings an incredible depth of flavor that pairs beautifully with the brown butter glaze.
Vanilla Bean Paste: A few teaspoons give an aromatic punch and beautiful specks throughout the glaze.
Brown Sugar: It adds caramel notes to both the batter and glaze; trust me, it’s worth it!

How to Make Old-Fashioned Buttermilk Donuts Bars with Brown Butter Maple Vanilla Bean Glaze
Preheat your oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan with nonstick spray or line it with parchment paper for easy removal later.
Mix dry ingredients: In a large bowl, whisk together flour, sugar, baking powder, and salt until well combined. This step ensures even distribution of each ingredient throughout your batter.
Combine wet ingredients: In another bowl, mix buttermilk, eggs, melted butter, and maple syrup until smooth. The batter should look silky and glossy at this point—just like how we want our donuts to turn out!
Combine mixtures: Gradually fold the wet ingredients into dry ingredients using a spatula until just combined. Be careful not to overmix; we want those fluffy textures!
Pour into pan: Pour the batter into your prepared baking pan and spread it evenly. Tap lightly on the counter to release any air bubbles trapped inside.
Bake: Bake in the preheated oven for 25-30 minutes or until a toothpick inserted comes out clean. Your kitchen will smell heavenly!
Prepare glaze: While donuts cool slightly, melt unsalted butter in a small saucepan over medium heat until it turns golden brown and smells nutty. Remove from heat before adding maple syrup and vanilla bean paste.
Glaze donuts: Once cooled slightly but still warm, drizzle or dip each bar generously into the brown butter glaze before letting them set on a wire rack.
