Ingredients

• 170 grams Unsalted butter
• 200 grams Light brown sugar
• 50 grams Granulated sugar
• 2 pieces Large eggs
• 2 teaspoons Vanilla extract
• 200 grams All-purpose flour
• 1 teaspoon Baking powder
• 0.5 teaspoons Salt
• 1 teaspoon Ground cinnamon
• 40 grams Unsalted butter (for cinnamon swirl)
• 65 grams Brown sugar (for cinnamon swirl)
• 1.5 teaspoons Ground cinnamon (for cinnamon swirl)

Directions

Step 1

Preheat the oven to 175°C (350°F) and grease or line a 9x9-inch baking pan with parchment paper for easy removal.

Step 2

Melt 170 grams of unsalted butter in a small saucepan or in the microwave, and let it cool slightly.

Step 3

In a large mixing bowl, combine the melted butter, light brown sugar, and granulated sugar. Whisk until smooth and fully combined.

Step 4

Add the eggs and vanilla extract to the mixture. Whisk until the batter is thick and silky.

Step 5

In a separate bowl, sift together the all-purpose flour, baking powder, salt, and ground cinnamon. Gradually fold the dry ingredients into the wet mixture until just combined. Do not overmix.

Step 6

For the cinnamon swirl, melt 40 grams of unsalted butter. In a small bowl, mix the melted butter with 65 grams of brown sugar and 1.5 teaspoons of ground cinnamon to form a thick paste.

Step 7

Pour the blondie batter into the prepared baking pan and spread it out evenly using a spatula.

Step 8

Spoon the cinnamon swirl mixture in dollops over the surface of the batter. Use a knife or skewer to create a swirling pattern by dragging it through the batter and cinnamon mixture.

Step 9

Bake in the preheated oven for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with a few moist crumbs.

Step 10

Allow the blondies to cool completely in the pan before slicing into 12 squares and serving. Enjoy!
