Brown Butter Peach Blondies with Fresh Milled Flour

At our bakery, The Flour Barn, fall is our favorite season. Sweater weather, cozy drinks, and—of course—seasonal baking! That’s where these Brown Butter Peach Blondies come in. Inspired by our bakery’s Apple Blondie recipe, these bars bring together nutty browned butter, sweet peaches, and the rich texture of freshly milled flour. It’s one of those peach recipes that just tastes like sunshine and comfort all at once.

Why Use Freshly Milled Flour

Growing up, my mom milled her own flour for baking bread every week. Today, more people are returning to this practice, and for good reason!

Health

Even with butter and sugar, baked goods made with freshly milled flour retain the nutrients found in the entire wheat berry—unlike store-bought purpose flour, which often lacks key nutrients to extend shelf life.

Flavor

Freshly milled flour brings a deep, nutty aroma and earthy complexity that pairs beautifully with browned butter and fruit. These blondies benefit from both the flavor of fresh flour and the richness of browned butter—an unbeatable combo!

Texture

Fresh flour doesn’t develop gluten as aggressively as white flour, meaning your blondies stay tender instead of tough. That’s why it shines in recipes like waffles, pancakes, and these fudgy brownies. To explore a more in depth look at the difference between fresh milled flour and AP flour, read more here.

The Magic of Browned Butter

If you’ve never made browned butter, get ready for a game-changer. When butter browns, it transforms into a golden liquid gold full of toasty depth and a signature nutty aroma. It gives these blondies a rich, complex flavor that regular butter just can’t match.

How to Brown Your Butter

1. Start with salted butter in a light-colored skillet over medium heat.
2. As it melts, it will foam and sizzle.
3. Watch closely as it shifts to a golden brown color and releases that amazing nutty aroma.
4. Remove it from heat immediately and pour into a safe bowl to stop cooking.

Tip: Use a wooden spoon and stir gently while the butter browns. You’ll know it’s done when those toasty brown bits settle at the bottom.

How to Make Easy Peach Blondies

This recipe is a crowd-pleaser and comes together with simple steps and a few bowls.

Ingredients:

• 4 fresh peaches, peeled and cubed
• 1 1/4 cup browned butter, divided
• 2 1/3 cups freshly milled flour
• 1 2/3 cup light brown sugar
• 2 eggs, room temperature
• 1 tsp vanilla extract
• 1 tsp coarse salt
• 1 ½ tsp baking powder
• 1/2 tsp baking soda
• 1 tsp cinnamon

Instructions:

1. Preheat oven to 350°F and grease a prepared baking pan lined with parchment paper overhang.
2. Brown your butter and let it cool for about 5-10 minutes.
3. In a large mixing bowl, whisk together brown sugar, eggs, vanilla, and 1 cup of the cooled browned butter.
4. In a medium bowl, whisk together your dry ingredients: flour, salt, baking powder, baking soda, and cinnamon.
5. Add the flour mixture to the wet ingredients and stir until just combined. A dutch whisk works great for this.
6. Gently fold in your sliced peaches.
7. Pour the blondie batter into your prepared pan and smooth into an even layer.
8. Bake for 30-35 minutes or until a toothpick inserted comes out with moist crumbs.
9. Let cool on a wire rack.

Simple Icing

While the blondies cool, make a quick icing:

• Combine leftover browned butter, milk, and powdered sugar.
• Whisk until smooth, then drizzle over the cooled blondies. You can warm it slightly to make spreading easier.

Serving & Storing

These blondies are best enjoyed warm, ideally with a scoop of vanilla ice cream and a drizzle of caramel sauce for a decadent treat. Store leftovers in an airtight container for up to 3 days… if they last that long!

Why You’ll Love These

From the first bite, the gooey texture and rich, brown butter flavor shine through. The fresh peaches add brightness and a slight tartness that balances beautifully with the light brown sugar.
