Ingredients
  • 2 1/2 cups All-purpose flour
  • 2 teaspoons Baking powder
  • 1/2 teaspoon Salt
  • 1 cup (2 sticks) Unsalted butter, melted
  • 2 cups Brown sugar, packed
  • 2 large Eggs
  • 2 teaspoons Vanilla extract
  • 1/4 cup Milk
  • 1/2 cup Caramel sauce
  • 1/2 cup Chopped pecans or walnuts (optional)

Get Started

Preheat your oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan. This will prevent the blondies from sticking and ensure easy removal.

Combine Dry Ingredients

In a medium bowl, whisk together the flour, baking powder, and salt. This ensures that the baking powder is evenly distributed for a consistent rise.

Mix Wet Ingredients

In a large bowl, combine the melted butter and brown sugar. Mix until well combined and smooth. The brown sugar adds a rich, molasses-like flavor to the blondies.

Add Eggs and Vanilla

Beat in the eggs one at a time, then stir in the vanilla extract. Ensure each egg is fully incorporated before adding the next. This helps create a smooth batter.

Combine Wet and Dry

Gradually add the dry ingredients to the wet ingredients, alternating with the milk, beginning and ending with the dry ingredients. Mix until just combined. Be careful not to overmix; a few lumps are okay.

Add Caramel Swirl

Pour the batter into the prepared pan and spread evenly. Drizzle the caramel sauce over the batter, then use a knife or skewer to swirl it in. This creates a beautiful and flavorful caramel swirl throughout the blondies.

Bake

Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. The blondies should be golden brown on top.

Cool and Serve

Let the blondies cool in the pan completely before cutting into squares and serving. Optionally, sprinkle with chopped pecans or walnuts for added flavor and texture.
