Ingredients & Prep

Main Ingredients Prep

All-purpose flour – Spoon and level for accurate measuring.
Butter – Softened to room temperature for easy mixing.
Sugar – Granulated sugar keeps the bars light and classic.
Eggs – Bring to room temperature for smooth batter.

Seasonings, Sauces, or Flavor Base

Vanilla extract – Essential for classic sugar cookie flavor.
Almond extract (optional) – Adds bakery-style depth.
Salt – Balances sweetness and enhances flavor.

Pantry Staples

Baking powder – Helps the bars rise slightly and stay soft.
Powdered sugar – Used for the frosting.
Milk or cream – Adjusts frosting consistency.
Food coloring or sprinkles (optional) – For decoration.

Step-by-Step Cooking Instructions

Pre-Cooking Prep

Preheat your oven to 350°F. Line a 9×13-inch baking pan with parchment paper or lightly grease it. This makes removing and slicing the bars much easier.

Cooking Method (Times & Temps)

In a large bowl, cream butter and sugar together until light and fluffy.
Add eggs and vanilla (and almond extract if using). Mix until smooth.
In a separate bowl, whisk flour, baking powder, and salt.
Gradually mix dry ingredients into the wet ingredients until just combined.
Press the dough evenly into the prepared pan.
Bake for 18–22 minutes, until the edges are lightly golden and the center is set.

Doneness or Texture Check

The bars should look slightly underbaked in the center but not jiggly. A toothpick inserted should come out mostly clean with a few soft crumbs.

Resting or Final Touches

Allow the cookie bars to cool completely before frosting. This prevents the frosting from melting and sliding off.

Pro Tips for Perfect Results

Common Mistakes to Avoid

Overbaking – This leads to dry bars instead of soft ones.
Frosting while warm – Always wait until fully cooled.
Overmixing the dough – Mix just until combined for tender texture.

FAQs

Can I make this ahead of time?

How do I fix common mistakes?
