Ingredient Notes & Details

Butter
Use unsalted butter for better control of flavor. It should be softened, not melted, to create that perfect creamy base.

Granulated Sugar
Provides sweetness and helps create that slightly crisp top layer once baked.

Brown Sugar
Adds moisture and a subtle caramel flavor, giving the bars their signature chewiness.

Eggs
Bind everything together and give structure. Room temperature eggs work best for even mixing.

Vanilla Extract
Enhances the overall flavor — don’t skip it. Use pure vanilla for the best result.

All-Purpose Flour
The base of the recipe. Be careful not to overmeasure — spoon and level for accuracy.

Baking Powder
Gives the bars a slight lift, keeping them soft rather than dense.

Salt
Balances the sweetness and enhances all the flavors.

Optional Add-ins (Chocolate Chips, Nuts)
Perfect for variation. Chocolate adds richness, while nuts bring a bit of crunch.

Step-by-Step Instructions

Step 1: Preheat and Prepare the Pan
Preheat your oven to 180°C (350°F). Line a baking pan with parchment paper or lightly grease it to prevent sticking.

Step 2: Cream the Butter and Sugars
In a large bowl, beat the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy. This step is key for creating that soft, tender texture.

Step 3: Add Eggs and Vanilla
Mix in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract.

Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking powder, and salt. This helps distribute everything evenly.

Step 5: Mix Wet and Dry Ingredients
Gradually add the dry mixture to the wet ingredients. Mix just until combined — avoid overmixing, as it can make the bars dense.

Step 6: Add Optional Ingredients
Fold in chocolate chips or nuts if using. This is where you can customize your easy Tom Thumb Bars.

Step 7: Spread the Batter
Pour the batter into your prepared pan and spread it evenly with a spatula.

Step 8: Bake to Perfection
Bake for 25–30 minutes, or until the top is lightly golden and a toothpick inserted in the center comes out clean.

Step 9: Cool Before Cutting
Allow the bars to cool completely in the pan. This helps them set and makes cutting easier.

Step 10: Slice and Serve
Cut into squares or rectangles and enjoy. The edges will be slightly crisp, while the center stays soft and chewy.
