Ingredients You'll Need
- 2 ½ cups all-purpose flour
- 2 teaspoon baking powder
- 1 teaspoon baking soda
- ½ teaspoon ground nutmeg (freshly grated if possible for more flavor)
- 1 teaspoon salt
- ½ cup unsalted butter, softened (I love using European-style butter for a richer taste)
- ¾ cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- ¾ cup buttermilk (if you don't have buttermilk, you can make your own by adding 1 tablespoon vinegar or lemon juice to milk and letting it sit for 5 minutes)
- ½ cup unsalted butter (for the glaze)
- 1 ½ cups powdered sugar
- 2 tablespoon pure maple syrup (use real maple syrup for the best flavor)
- 1 teaspoon vanilla bean paste (or you can substitute with extra vanilla extract)
- 1-2 tablespoon milk (for thinning the glaze, add gradually until you reach your desired consistency)
Step-by-Step Instructions
Preheat the Oven
- First things first, preheat your oven to 350°F (175°C). This ensures that your donut bars bake evenly and come out perfectly fluffy.
- While the oven is heating, grease a baking pan (a 9x13-inch pan works great) with a bit of butter or cooking spray. This will help your delicious bars slide right out once they're baked.
Make the Donut Bar Batter
- In a mixing bowl, combine 2 ½ cups of all-purpose flour, 2 teaspoon of baking powder, 1 teaspoon of baking soda, ½ teaspoon of ground nutmeg, and 1 teaspoon of salt. Give it a quick whisk to blend everything together.
- In another bowl, cream together ½ cup of softened unsalted butter and ¾ cup of granulated sugar until the mixture is light and fluffy. This usually takes about 2-3 minutes, and you want to see a nice pale color.
- Add in 2 large eggs and 1 teaspoon of vanilla extract to the butter mixture. Mix well until everything is combined and smooth. Don't worry if it looks a bit curdled; it'll come together in the next step!
- Now, alternate adding the dry ingredients and ¾ cup of buttermilk to the butter mixture. Start with about a third of the dry mix, then add half of the buttermilk, and continue alternating until everything is just combined. Be careful not to overmix; a few lumps are totally okay!
Bake the Donut Bars
- Pour the batter into your prepared baking pan, spreading it out evenly with a spatula.
- Pop it in the oven and bake for 15-20 minutes. You'll know they're done when a toothpick inserted in the center comes out clean or with just a few crumbs.
- Once baked, remove the pan from the oven and let the donut bars cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely.
Prepare the Glaze
- While the donut bars are baking, grab a saucepan and melt ½ cup of unsalted butter over medium heat. Keep an eye on it; we want it melted, not browned.
- Once melted, remove the pan from the heat and whisk in 1 ½ cups of powdered sugar, 2 tablespoon of pure maple syrup, and 1 teaspoon of vanilla bean paste (or extra vanilla extract). Mix until you have a smooth glaze.
- If your glaze seems too thick, add 1-2 tablespoon of milk gradually until you reach the desired consistency. It should be pourable but not too runny!
Drizzle and Serve
- Once the donut bars are completely cooled, place them on a serving platter or leave them in the pan if you prefer.
- Generously drizzle the glaze over the top of the bars, letting it cascade down the sides for that beautiful finish.
- Now, it's time to enjoy! Cut them into bars and serve them warm or at room temperature. Sit back and watch your friends and family devour these delightful treats!
Variations
- For a chocolate twist, add ½ cup of cocoa powder to the dry ingredients.
- Incorporate seasonal spices like cinnamon or pumpkin spice for a fall-inspired version.
- Use almond milk or coconut milk for a dairy-free adaptation.
- Try adding chopped nuts or chocolate chips to the batter for extra texture.
- For a lighter version, substitute half the butter with unsweetened applesauce.
Serving and Storage Tips
Serving
These Old-Fashioned Buttermilk Donut Bars are delightful warm or at room temperature. Serve them on a pretty platter, and don't forget to have extra napkins handy for the glaze! They pair beautifully with coffee, tea, or a tall glass of cold milk.
Storage
To keep your donut bars fresh, store them in an airtight container at room temperature for up to 3 days. If you want to keep them longer, freeze them wrapped tightly in plastic wrap for up to a month. Just thaw at room temperature before enjoying!
Helpful Notes
- For a richer flavor, consider browning the butter for the glaze.
- Feel free to substitute the granulated sugar with coconut sugar for a deeper, caramel-like taste.
- If you have a nut allergy, use a dairy-free butter alternative for both the batter and glaze.
- Adding a pinch of cinnamon to the batter can enhance the warmth of the flavors.
- These bars can be dressed up with sprinkles or a dusting of powdered sugar for special occasions!
