Ingredients You’ll Need

For the Blondie Batter:

• 1 cup unsalted butter, melted and slightly cooled
• 1½ cups light brown sugar, packed
• ½ cup granulated sugar
• 2 large eggs
• 2 tsp vanilla extract
• 2 cups all-purpose flour
• 1½ tsp cream of tartar
• ½ tsp baking soda
• ½ tsp salt
• 1½ tsp ground cinnamon

For the Cinnamon Swirl Topping:

• ¼ cup granulated sugar
• 1 tbsp ground cinnamon
• 2 tbsp unsalted butter, melted

Optional Garnish:

• Extra pinch of cinnamon sugar for dusting
• Drizzle of vanilla glaze or white chocolate

Tools You’ll Need

• 9×13-inch baking pan
• Mixing bowls
• Whisk and spatula
• Measuring cups and spoons
• Parchment paper (for easy removal)

Step-by-Step Instructions

Step 1: Preheat & Prepare the Pan

1. Preheat your oven to 350°F (175°C).
2. Line a 9×13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Lightly grease the paper.

Step 2: Mix the Wet Ingredients

1. In a large mixing bowl, whisk together the melted butter, brown sugar, and granulated sugar until well combined and glossy.
2. Add the eggs and vanilla extract, whisking until smooth.

Step 3: Add the Dry Ingredients

1. In the same bowl, stir in flour, cream of tartar, baking soda, salt, and cinnamon.
2. Mix until just combined—don’t overmix. The batter will be thick.

Step 4: Spread Batter into the Pan

1. Transfer the batter to the prepared baking pan.
2. Use a spatula to spread it evenly into the corners and smooth the top.

Step 5: Make the Cinnamon Swirl

1. In a small bowl, combine granulated sugar and cinnamon.
2. Stir in melted butter until a crumbly paste forms.

Step 6: Swirl it In

1. Drop spoonfuls of the cinnamon-sugar mixture evenly over the top of the batter.
2. Use a butter knife or skewer to gently swirl it into the top layer of the blondie batter. Don’t mix it in completely—you want distinct swirls.

Step 7: Bake

1. Bake for 25–30 minutes or until the edges are golden brown and a toothpick inserted in the center comes out with just a few moist crumbs.
2. Don’t overbake—they’ll continue to firm up as they cool.

Step 8: Cool & Slice

1. Let the blondies cool completely in the pan on a wire rack.
2. Once cooled, lift them out using the parchment overhang and cut into squares.

Tips for Perfect Snickerdoodle Blondies
Use Room Temperature Eggs – Helps them blend better into the batter.
Don’t Overbake – Keep them chewy by removing from the oven when they’re just set.
Swirl Gently – You want defined cinnamon ribbons, not a full mix.
Add a Glaze – A light vanilla drizzle takes these over the top.
Let Cool Before Slicing – This helps them set and gives cleaner cuts.

Serving Suggestions
Serve with a scoop of vanilla ice cream for an indulgent treat.
Pair with a hot cup of chai tea, coffee, or warm apple cider.
Great for holiday dessert platters or cookie exchanges.

How to Store & Freeze

Storing:

• Room Temperature: Keep in an airtight container for up to 4 days.
• Refrigerator: Store for up to 1 week if you prefer them chilled.

Freezing:

• Wrap individual blondies tightly in plastic wrap, then store in a freezer-safe container or zip-top bag for up to 2 months.
• Thaw at room temperature or warm briefly in the microwave for a gooey bite.

Frequently Asked Questions

1. Can I make these without cream of tartar?
Yes, but cream of tartar gives that classic snickerdoodle tang. You can substitute with 1 tsp lemon juice or white vinegar added to the batter.

2. Can I add mix-ins like white chocolate chips?
Absolutely! Fold in ½ cup of white chocolate chips or even chopped nuts before baking for extra texture.

3. How do I know when they’re done?
The edges will be golden and the center set but slightly soft. A toothpick should come out with a few moist crumbs, not wet batter.

4. Can I use dark brown sugar?
Yes, but it will create a deeper, more caramel-like flavor. Either works great.

5. What if I want smaller batches?
You can halve the recipe and bake in an 8×8-inch pan. Bake time will be closer to 22–25 minutes.
