Step‑by‑Step Instructions for Cinnamon Swirl Snickerdoodle Blondies Step 1: Preheat and Prepare Begin by preheating your oven to 350°F (175°C). While it warms up, take a 9×13-inch baking dish and grease it generously with cooking spray or butter. To ensure easy removal of your blondies later, line the dish with parchment paper, allowing some excess to hang over the edges. This will become a handy lift-out feature once the blondies cool. Step 2: Mix the Wet Ingredients In a large mixing bowl, whisk together the melted butter, brown sugar, and granulated sugar until the mixture is smooth and well combined. This should take about 2-3 minutes. Next, crack in the eggs one at a time, whisking after each addition, then stir in the vanilla extract until the mixture has a glossy texture. Step 3: Combine Dry Ingredients In a separate bowl, sift together the all-purpose flour, cream of tartar, baking soda, and salt. This ensures the dry ingredients are evenly mixed and will help to create that ideal chewy consistency. Gradually incorporate the dry mixture into the wet ingredients, stirring gently until just combined. Avoid overmixing to achieve the perfect texture for your Cinnamon Swirl Snickerdoodle Blondies. Step 4: Make the Cinnamon-Sugar Swirl In a small bowl, combine granulated sugar and cinnamon for the swirl. Stir in a bit of melted butter until the mix resembles damp sand. This cinnamon-sugar blend adds the signature flavor that makes the blondies so irresistible. Set this aside as you prepare to layer your batter in the baking dish. Step 5: Layer the Blondie Batter Spread half of the blondie batter evenly across the prepared baking dish, creating a smooth layer. Then, sprinkle the cinnamon-sugar mixture over the batter, ensuring even coverage. Next, dollop the remaining batter on top of the cinnamon layer and use a knife to create a gentle swirl, mixing the two layers slightly for that beautiful cinnamon swirl effect. Step 6: Bake it to Perfection Carefully place your baking dish in the preheated oven and bake for 30-35 minutes. You’ll know they’re done when the edges turn a lovely golden brown and a toothpick inserted in the center comes out with moist crumbs – not wet batter. Keep an eye on them in the last few minutes to avoid overbaking! Step 7: Cool and Slice Once baked, remove the blondies from the oven and let them cool in the pan for about 20 minutes. This step is crucial for better slicing. After cooling, use the parchment overhang to lift the blondies out of the pan. Place them on a cutting board and slice into squares. Serve warm or at room temperature, and relish your homemade Cinnamon Swirl Snickerdoodle Blondies!

You can prepare the blondie batter and store it in the refrigerator for up to 24 hours in advance, which helps to develop the flavors. Additionally, the cinnamon-sugar swirl mixture can be made ahead and stored in an airtight container for about 3 days. When you’re ready to bake, simply spread the chilled batter into the baking dish, sprinkle the prepared cinnamon-sugar over it, swirl, and pop it in the oven. This ensures that your blondies come out just as delicious as if made fresh, allowing you to enjoy a sweet treat with minimal effort on your busy days! How to Store and Freeze Cinnamon Swirl Snickerdoodle Blondies Room Temperature: Keep your blondies in an airtight container at room temperature for up to 4 days to maintain their chewiness and flavor. Fridge: If you opt to refrigerate them, your blondies can last up to 7 days; just be sure they are wrapped tightly to avoid drying out. Freezer: For longer storage, wrap individual blondies in plastic wrap followed by aluminum foil, and freeze for up to 3 months; simply thaw at room temperature before enjoying. Reheating: To bring back their soft texture, reheat blondies in the microwave for about 10-15 seconds or in the oven at 350°F (175°C) for a few minutes. Expert Tips for Cinnamon Swirl Snickerdoodle Blondies Prevent Overmixing: Stir the batter just until combined. Overmixing can lead to dense, heavy blondies instead of the desired chewy texture. Let Them Cool: Allowing the blondies to cool completely before slicing not only creates cleaner edges but also enhances the flavors as they meld together. Check Doneness Early: Start checking for doneness a few minutes before the recommended baking time. You want moist crumbs—not wet batter—on your toothpick. Customize with Care: For extra flavor, consider adding spices like nutmeg or mixing in chopped nuts. Just remember to keep balance in mind to avoid overpowering the cinnamon swirl. Layer Evenly: Spread the blondie batter out evenly in the pan. This ensures consistent baking and a pleasing swirl effect that enhances the overall appearance of your Cinnamon Swirl Snickerdoodle Blondies.

Always keep your delightful blondies out of reach and consider making pet-friendly treats instead! What if my blondies are too dry or crumbly? If your blondies turn out dry, it may be due to overbaking or too much flour. Always measure your flour correctly by spooning it lightly into the measuring cup and leveling it off.
