Ingredients
For the Bars
- 1 ½ cups all-purpose flour
- ½ teaspoon baking powder
- ½ teaspoon fine sea salt
- 1 ½ cups light brown sugar (packed)
- ½ cup unsalted butter (melted)
- 2 large eggs
- 1 teaspoon vanilla bean paste
Cinnamon Sugar Swirl
- 2 tablespoons granulated sugar
- 1 tablespoon ground cinnamon
Cream Cheese Icing
- 4 ounces cream cheese (softened)
- 2 ounces unsalted butter (softened)
- 1 cup powdered sugar
- ½ teaspoon vanilla bean paste
Instructions
- Preheat Oven and Prepare Pan: Preheat your oven to 350 degrees F (175 degrees C). Line a 9×13-inch baking dish with parchment paper or lightly spray it with baking spray to prevent sticking.
- Mix Dry Ingredients: In a medium bowl, combine the all-purpose flour, baking powder, and fine sea salt. Stir well and set aside.
- Combine Wet Ingredients: In a large bowl, mix the packed light brown sugar with melted unsalted butter until well incorporated.
- Add Eggs and Vanilla: Whisk in the eggs and vanilla bean paste into the sugar and butter mixture until the batter is smooth and homogenous.
- Combine Dry and Wet: Gradually add the dry ingredients to the wet ingredients and stir until just combined to avoid overmixing.
- Press Batter into Pan: Spread and press the batter evenly into the prepared baking dish to form a smooth layer.
- Prepare Cinnamon Sugar Swirl: In a small bowl, mix the granulated sugar and ground cinnamon together.
- Add Cinnamon Lines: Pour the cinnamon sugar mixture in two long lines down the length of the batter in the pan.
- Create Swirls: Using a butter knife, gently swirl through the cinnamon sugar and batter to create a marbled effect.
- Bake the Bars: Place the baking dish in the oven and bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean.
- Cool Completely: Remove the pan from the oven and allow the bars to cool completely before frosting.
- Make Cream Cheese Icing: While the bars cool, beat the softened cream cheese and butter together with an electric hand mixer in a medium-sized bowl until smooth and creamy.
- Add Powdered Sugar: Gradually add the powdered sugar a little at a time, mixing constantly until fully incorporated.
- Finish Icing: Stir in the vanilla bean paste and beat the mixture on high speed for 2 minutes until light and fluffy.
- Frost the Bars: Cut the cooled bars into servings and either spread the cream cheese frosting over the entire bars or drizzle in a zigzag pattern as desired.
Notes
- For a thicker swirl, add more cinnamon sugar and make additional swirls in the batter.
- If desired, substitute vanilla bean paste with vanilla extract in equal amounts.
- The frosting recipe makes enough for the entire batch; use half if you prefer a light drizzle rather than full coverage.
- Make sure the bars are completely cooled before applying the frosting to prevent melting.
- Store the bars in an airtight container in the refrigerator for up to 5 days.
