How to Make Old-Fashioned Buttermilk Donut Bars

Step 1: Prepare Your Ingredients and Pan

Start by preheating your oven to 350°F (175°C) and greasing an 8×8-inch baking pan to ensure your donut bars come out cleanly. Gather all your measured ingredients before you begin mixing to keep the process smooth and organized.

Step 2: Mix Dry Ingredients

In a large bowl, whisk together all-purpose flour, baking powder, baking soda, and sugar. This dry mix forms the base for your donut bars, so ensure everything is evenly combined to avoid any lumps or uneven rising.

Step 3: Combine Wet Ingredients

In another bowl, beat the eggs lightly, then add buttermilk, vegetable oil, vanilla extract (natural), and vegetarian Worcestershire sauce. Whisk these together until smooth and uniform in texture, ready to be folded into the dry ingredients.

Step 4: Combine Wet and Dry Ingredients

Slowly add the wet mixture to the dry ingredients, stirring gently to combine. Be careful not to overmix to maintain that tender crumb characteristic of the best Old-Fashioned Buttermilk Donut Bars. The batter should be thick but pourable.

Step 5: Bake the Batter

Pour the batter into your prepared pan and smooth out the top evenly. Place it in the preheated oven and bake for 25 to 30 minutes or until a toothpick inserted in the center comes out clean. The edges will turn golden brown and the bars will emit a delicious aroma that signals they are done.

Step 6: Prepare the Glaze

While the bars are baking, whisk powdered sugar, grape juice, and a natural gelling agent together until you achieve a smooth, slightly thick glaze. Adjust the thickness by adding more powdered sugar or grape juice as needed.

Step 7: Cool and Glaze

Allow the bars to cool for about 10 minutes before spreading the glaze generously over the top. Let the glaze set for another 15 minutes at room temperature or pop them in the fridge briefly to speed things along.

Step 8: Slice and Serve

Cut into squares or rectangles, and your Old-Fashioned Buttermilk Donut Bars are ready to delight friends and family with their tender crumb and luscious sweet finish.

Pro Tips for Making Old-Fashioned Buttermilk Donut Bars

• Fresh Ingredients: Use fresh baking powder and baking soda for optimal rising power and fluffy texture.
• Don’t Overmix: Stir the batter just until combined to keep the crumb tender and light.
• Room Temperature Ingredients: Bring eggs and buttermilk to room temperature before mixing for better incorporation.
• Even Layering: Spread the batter evenly in the pan for consistent baking and uniformness in texture.
• Perfect Glaze Consistency: Adjust grape juice and powdered sugar proportions to your preferred glaze thickness for easy spreading.
