1. Prep Your Oven and Pan

• Preheat your oven to 350°F (175°C).
• Line an 8×8-inch baking pan with parchment paper or grease it lightly with butter.

2. Make the Bar Batter

• In a large bowl, whisk together melted butter, brown sugar, and granulated sugar until smooth.
• Add in the eggs and vanilla extract, whisking until fully combined.
• In a separate bowl, whisk together the flour, baking powder, salt, and cinnamon.
• Gradually fold the dry ingredients into the wet mixture until just combined—don’t overmix!

3. Create the Cinnamon Swirl

• In a small bowl, mix brown sugar, cinnamon, and melted butter to create a thick paste.
• Pour half of the batter into the prepared pan.
• Drizzle half of the cinnamon swirl mixture over the batter and use a knife or toothpick to create a marbled effect.
• Pour the remaining batter on top and repeat the swirl pattern with the remaining cinnamon mixture.

4. Bake to Perfection

• Bake for 25–30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
• Let the bars cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.

5. Make the Cream Cheese Glaze

• In a medium bowl, beat together cream cheese, powdered sugar, milk, and vanilla extract until smooth.
• Drizzle the glaze over the cooled bars for that classic cinnamon roll flavor.

6. Slice and Serve

• Cut into squares or bars and enjoy! These are perfect warm or at room temperature.
