Step‑by‑Step Instructions for Old-Fashioned Buttermilk Donut Bars

Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). While it's warming up, grease or line a 9x13-inch baking pan with parchment paper for easy removal later. This simple preparation ensures your Old-Fashioned Buttermilk Donut Bars will bake evenly and come out perfectly.

Step 2: Combine Dry Ingredients
In a medium bowl, whisk together all-purpose flour, baking powder, baking soda, ground nutmeg, and salt until well combined. This dry mixture is essential for creating the classic flavor and tender texture of your donut bars. Set this bowl aside as you move to the next step.

Step 3: Cream Butter and Sugar
In a large mixing bowl, use an electric mixer to beat the softened unsalted butter and granulated sugar together until the mixture is light and fluffy, approximately 2-3 minutes. This process incorporates air, which is key for a light texture in your Old-Fashioned Buttermilk Donut Bars.

Step 4: Add Eggs and Vanilla
Add the eggs to the butter mixture one at a time, mixing well after each addition to ensure they are fully incorporated. Then stir in the vanilla extract, blending everything smoothly. This step enriches the flavor and binds your batter together, creating a beautifully cohesive mixture.

Step 5: Mix in Dry and Wet Ingredients
Gradually add the flour mixture to the butter mixture, alternating with the buttermilk. Start and end with the flour mixture, mixing just until combined. The batter should appear thick yet smooth. Be careful not to over-mix; a gentle fold ensures tender bars in your Old-Fashioned Buttermilk Donut Bars.

Step 6: Spread and Bake
Pour the batter into the prepared baking pan, spreading it evenly with a spatula. Smooth the top to ensure uniform baking. Place in the preheated oven and bake for 22-25 minutes, or until a toothpick inserted into the center comes out clean, indicating they’re done.

Step 7: Cool Completely
Once baked, remove the pan from the oven and allow the bars to cool in the pan for about 10 minutes. Then, transfer the bars to a wire rack to cool completely. Cooling is essential to allow the glaze to adhere properly, leading to the perfect finish on your Old-Fashioned Buttermilk Donut Bars.

Step 8: Prepare the Glaze
While the bars cool, prepare the dreamy glaze. In a small saucepan, melt the butter over medium heat until it turns golden brown, releasing a nutty aroma, about 5-7 minutes. Then, whisk in the powdered sugar, maple syrup, and vanilla bean paste until the glaze is smooth and glossy. Adjust with a splash of milk if necessary.

Step 9: Glaze the Bars
Once the donut bars are completely cool, pour the glaze over the top, allowing it to drip down the sides for a beautiful finish. Let the glaze set for about 15 minutes at room temperature before slicing the bars into rectangles. Your Old-Fashioned Buttermilk Donut Bars are now ready to indulge!

Expert Tips for Old-Fashioned Buttermilk Donut Bars

Room Temperature Ingredients: Ensure all your ingredients, especially butter and eggs, are at room temperature for a smoother batter and better texture.

Glaze Consistency: If the glaze appears too thick, add a small splash of milk to reach your desired pourable consistency, ensuring an even coating.
Cool Completely: Allow the bars to cool completely before glazing to prevent the frosting from soaking in or running off. This step is crucial for that perfect finish.
Store Properly: Keep leftover bars in an airtight container at room temperature for up to 3 days or refrigerate for a week, ensuring they stay fresh and delicious!

Old-Fashioned Buttermilk Donut Bars Recipe FAQs

How do I choose the right buttermilk for the recipe?
Absolutely! When selecting buttermilk, look for a fresh carton with a clean expiration date to ensure maximum flavor and acidity, which contributes to the tenderness of your donut bars. If you can't find buttermilk, mixing milk with 1 tablespoon of vinegar or lemon juice for each cup will yield a similar tangy effect.

How should I store leftover Old-Fashioned Buttermilk Donut Bars?
After enjoying your donut bars, store any leftovers in an airtight container at room temperature for up to 3 days. If you want to extend their shelf life, refrigerate them for up to a week. Just ensure they are well-wrapped to prevent them from drying out or picking up odors!

Can I freeze the donut bars, and if so, how?
Yes, you can freeze them! To do this, wrap each individual bar tightly in plastic wrap and then in aluminum foil, or place them in a freezer-safe airtight container. Frozen Old-Fashioned Buttermilk Donut Bars will keep well for up to 3 months. When you're ready to enjoy, simply thaw at room temperature or reheat briefly in the microwave or oven as described in the storage instructions.

What should I do if my donut bars turn out too dense or heavy?
If your donut bars come out too dense, it may be due to overmixing the batter, which can develop the gluten in flour and lead to a heavier texture. For next time, mix just until the dry ingredients are incorporated. Also, ensure your baking powder is still active—check the expiration date for optimal lift!

Is there a gluten-free version of Old-Fashioned Buttermilk Donut Bars?
Very much so! You can easily make these donut bars gluten-free by substituting all-purpose flour with a gluten-free flour blend. Ensure the blend contains xanthan gum for the best structure. Many brands have gluten-free all-purpose flour specifically made for baking, so check the label for best results.

Are there any allergy considerations I should know about?
Certainly! Keep in mind that this recipe contains common allergens like eggs, dairy, and gluten. To adapt for allergies, consider using egg replacers for vegans, almond or coconut milk for a lactose-free version, and gluten-free flour blends for those with celiac disease or gluten sensitivity. Always check ingredient labels to ensure safety.
