Step 1: Preheat the Oven

• Preheat your oven to 350°F (175°C).
• Line a 9×13-inch baking pan with parchment paper or grease it lightly with cooking spray for easy removal.

Step 2: Prepare the Dry Ingredients

• In a medium bowl, whisk together flour, baking soda, cinnamon, ginger, nutmeg, and salt.
• Set aside.

Step 3: Mix the Wet Ingredients

1. In a large bowl, cream together softened butter and brown sugar until light and fluffy (about 3-5 minutes).
2. Add the eggs, one at a time, beating well after each addition.
3. Mix in the molasses, ensuring a smooth and fully incorporated mixture.

Step 4: Combine Wet and Dry Mixtures

• Gradually fold the dry ingredients into the wet mixture using a spatula or a mixer on low speed.
• Stir until just combined; avoid overmixing to maintain a chewy texture.

Step 5: Bake the Bars

1. Pour the batter evenly into the prepared baking pan and smooth out the top with a spatula.
2. Bake for 25-30 minutes, or until the edges are set and a toothpick inserted into the center comes out clean.

Step 6: Cool and Slice

• Allow the bars to cool completely in the pan on a wire rack.
• Once cooled, lift them out using the parchment paper and slice them into squares or rectangles.
