Growing up in Monterey, my childhood kitchen was always alive with the comforting aromas of fresh herbs, roasting garlic, and the warm scent of baked bread. It was in that bustling heart of my family’s home that I first fell in love with the idea of turning simple ingredients into something magical—something that brings people together. These Irresistible Old-Fashioned Buttermilk Donut Bars are a perfect homage to those early days, where my Nonna Rosa’s old-world recipes met my mother Elena’s flair for improvisation. They’re simple, nostalgic, and just sweet enough to remind you of cozy afternoons spent with family and laughter echoing through the house.

- Total Time: 45 minutes
- Yield: 4 servings 1x
Ingredients
- 2 cups all-purpose flour (you can substitute with whole wheat pastry flour for a nuttier flavor)
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 teaspoon ground cinnamon
- 1/2 cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup buttermilk (if you don’t have buttermilk, mix 1 cup milk with 1 tablespoon lemon juice or vinegar and let sit for 5 minutes)
- 1/2 cup light brown sugar (for the topping)
- 2 teaspoons ground cinnamon (for the topping)
- 2 tablespoons unsalted butter, melted (for the topping)
Instructions
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan and line it with parchment paper, leaving some overhang for easy removal.
- In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and ground cinnamon. Set aside.
- In a large mixing bowl, cream the softened butter and granulated sugar together until light and fluffy. This usually takes about 3-4 minutes with a hand mixer. I always remember my mom telling me that patience at this step makes all the difference in the texture.
- Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.
- Alternately add the dry ingredients and the buttermilk to the butter mixture, starting and ending with the dry ingredients. Mix gently—don’t overwork the batter. The texture should be smooth and thick but pourable.
- Pour the batter evenly into the prepared pan, smoothing the top with a spatula.
- In a small bowl, combine the brown sugar, cinnamon, and melted butter for the topping. Sprinkle this mixture evenly over the batter.
- Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. The edges should be golden and the cinnamon topping slightly caramelized.
- Allow the bars to cool in the pan for at least 20 minutes before lifting them out with the parchment paper. Cut into squares or bars once fully cooled.
- Serve warm or at room temperature with a cup of coffee or a glass of milk—this is how my family always enjoyed them in Monterey. It’s a simple pleasure that never gets old.

Tips for Making the Best Irresistible Old-Fashioned Buttermilk Donut Bars
From my years of cooking alongside my mother and Nonna Rosa, I’ve learned that the best recipes come with a few little secrets: Learn more: Irresistible Biscoff Pumpkin Cheesecake Bars You Need to Try
- Don’t rush the creaming step: Creaming the butter and sugar until fluffy helps trap air, making the bars tender and light.
- Use fresh buttermilk: The tanginess of buttermilk is key to balancing the sweetness and giving the bars their signature moist crumb. When in doubt, homemade buttermilk (milk + acid) works beautifully.
- Watch your oven carefully: Even ovens can vary, so start checking around 30 minutes. The topping should bubble and lightly caramelize without burning.
- Customize your topping: Some days, I add chopped pecans or a sprinkle of nutmeg to the cinnamon sugar for extra warmth and crunch—feel free to experiment like my mom always did.
- Cut with a sharp knife: To keep the topping intact when slicing, dip your knife in hot water and wipe it clean between cuts.
Serving Suggestions and Pairings

These Irresistible Old-Fashioned Buttermilk Donut Bars are versatile and pair wonderfully with many beverages and snacks. I fondly recall our family breakfasts where these bars shared the table with homemade jam and freshly brewed coffee. Here are a few of my favorite ways to enjoy them:
- Serve warm, topped with a dollop of whipped cream or a drizzle of honey.
- Pair with a creamy latte or a rich hot chocolate for an indulgent treat.
- Add fresh berries or sliced bananas on the side to balance the richness.
- For a brunch spread, include alongside scrambled eggs and fresh fruit for a well-rounded meal.
- My daughters love them simply dusted with powdered sugar and a cold glass of milk—their favorite after-school snack.
Storage and Reheating Tips
One of the things I love most about these donut bars is how well they keep, which makes them perfect for busy families or those who love to bake ahead.
- Room temperature: Store bars in an airtight container for up to 2 days. They remain soft and flavorful.
- Refrigeration: Keep them in the fridge for up to 5 days. Bring to room temperature or warm slightly before serving.
- Freezing: Wrap individual bars tightly in plastic wrap and place in a freezer bag. Freeze for up to 3 months. Thaw overnight in the fridge and warm in a low oven or microwave.
- Reheating: I find reheating them for about 15-20 seconds in the microwave or 5-7 minutes at 325°F in the oven brings back their fresh-baked charm.
