Ingredient Breakdown

• 1 cup unsalted butter: Browning the butter adds a rich, nutty flavor that enhances the overall depth of the blondies.
• 1 1/2 cups brown sugar: Provides moisture and a slight molasses flavor for chewiness and sweetness.
• 1/2 cup granulated sugar: Balances the sweetness and contributes to the blondie’s texture.
• 2 large eggs: Bind the ingredients together and add structure to the blondies.
• 2 teaspoons vanilla extract: Adds a warm sweetness that complements the cinnamon and brown butter.
• 2 cups all-purpose flour: The base of the blondies, providing structure.
• 1 teaspoon baking powder: Gives a slight lift, keeping the blondies from being too dense.
• 1 teaspoon baking soda: Helps with leavening and browning.
• 1/2 teaspoon salt: Balances the sweetness and enhances flavor.
• 2 teaspoons ground cinnamon: The essential spice for that classic snickerdoodle flavor.

How to Prepare Snickerdoodle Blondies with Brown Butter Swirl

Step 1: Brown the butter

Start by melting the butter in a medium saucepan over medium heat. Keep stirring as it foams and then browns, releasing a nutty aroma. Once the butter turns a golden-brown color with small brown flecks, remove it from heat and let it cool slightly.

Step 2: Mix sugars and eggs

In a mixing bowl, combine the brown sugar and granulated sugar. Pour in the slightly cooled browned butter and mix well. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.

Step 3: Combine dry ingredients

In a separate bowl, whisk together the flour, baking powder, baking soda, salt, and ground cinnamon.

Step 4: Make the batter

Gradually add the dry ingredients to the wet ingredients, folding gently with a rubber spatula until just combined. Avoid overmixing to keep the blondies tender.

Step 5: Prepare the brown butter swirl

Reserve about 2 tablespoons of the browned butter before mixing it with the sugars and eggs. Once your batter is in the pan, drizzle this reserved brown butter on top and use a knife or skewer to swirl it through the batter, creating a marbled effect.

Step 6: Bake

Line your 8×8-inch pan with parchment paper and pour the batter in, spreading it evenly. Bake at 350°F (175°C) for 25–30 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs.

Step 7: Cool and slice

Allow the blondies to cool completely in the pan on a cooling rack before slicing into squares. This helps them set and prevents crumbling.

Allergy-Friendly Swaps

• Butter: Substitute with a plant-based butter alternative for a dairy-free option.
• Eggs: Use flax eggs (1 tablespoon flaxseed meal + 3 tablespoons water per egg) for an egg-free version.
• Flour: Swap all-purpose flour with a gluten-free flour blend, adjusting for texture.
• Sugars: Coconut sugar can replace brown sugar for a lower glycemic index.

Pitfalls & How to Prevent Them

• Overbaking: Blondies can quickly become dry if left in the oven too long. Start checking at 25 minutes.
• Butter browning: Watch the butter carefully to avoid burning—it should be golden brown, not blackened.
• Overmixing: Mix just until combined to keep the blondies tender and chewy.
• Swirl too much: Keep the brown butter swirl gentle to avoid mixing it fully into the batter, preserving that beautiful marbled look.

Storing, Freezing & Reheating

Store your Snickerdoodle Blondies with Brown Butter Swirl in an airtight container at room temperature for up to 4 days. For longer storage, wrap them tightly in plastic wrap and place them in a freezer-safe container or bag. They freeze beautifully for up to 3 months.

To reheat, simply let frozen blondies thaw at room temperature or warm individual pieces in the microwave for 10-15 seconds to bring back that freshly baked warmth and softness.

Quick Questions

Can I use salted butter instead of unsalted?

Yes, you can use salted butter, but skip adding extra salt in the recipe or reduce it slightly to avoid an overly salty taste.

Why does the brown butter swirl make such a difference?

The brown butter adds a rich, nutty flavor and a depth that contrasts beautifully with the sweetness and cinnamon, making these blondies uniquely delicious.

How do I know when the blondies are done?

Check by inserting a toothpick near the center; it should come out with a few moist crumbs but not wet batter. The edges should be golden and slightly pulling away from the pan.

Can I double this recipe for a larger batch?

Absolutely! Just double the ingredients and bake in a larger pan, adjusting the baking time as needed. Keep an eye on them to prevent overbaking.
