These Cinnamon Sugar Blondies are soft, chewy bars infused with warm cinnamon and vanilla flavors, topped with a crackly cinnamon-sugar crust reminiscent of classic snickerdoodles. Made in one bowl without a mixer, they combine buttery richness and chewy texture, perfect for any occasion from holiday treats to casual snacks.

Ingredients

Scale

For the Blondies:

170g (¾ cup) unsalted butter, melted
200g (1 cup) brown sugar, packed
50g (¼ cup) granulated sugar
1 large egg
1 egg yolk
2 tsp vanilla extract
190g (1 ½ cups) all-purpose flour
1 tsp baking powder
½ tsp salt
1 tsp ground cinnamon

For the Cinnamon Sugar Topping:

2 tbsp granulated sugar
1 tsp ground cinnamon

Optional Add-ins:

White or dark chocolate chips (quantity to preference)
Chopped pecans or walnuts (quantity to preference)
Caramel or white chocolate drizzle

Instructions

Preheat & Prepare: Preheat your oven to 175°C (350°F). Line an 8×8-inch (20×20 cm) baking pan with parchment paper and lightly grease it to prevent sticking.
Mix the Wet Ingredients: In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth. Add the egg, egg yolk, and vanilla extract, whisking until fully combined.
Add the Dry Ingredients: Stir in the all-purpose flour, baking powder, salt, and cinnamon until just combined. The batter should be thick; avoid overmixing to keep the blondies tender.
Spread & Add Topping: Pour the batter into the prepared pan and smooth the top evenly. Mix together 2 tablespoons granulated sugar and 1 teaspoon cinnamon, then sprinkle this mixture evenly over the batter to form a crackly cinnamon sugar crust.
Bake & Cool: Bake in the preheated oven for 20-25 minutes, or until the edges are set and a toothpick inserted in the center comes out with a few moist crumbs. Allow the blondies to cool completely in the pan before slicing into 12-16 squares.

Notes

For extra flavor and texture, fold in chocolate chips or chopped nuts into the batter before baking.
Do not overmix the batter once the flour is added to avoid dense blondies.
Allow the blondies to cool fully for clean slices and better texture.
Store in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
Drizzle caramel or melted white chocolate over the cooled blondies for an indulgent topping.
