Ingredients
- 1 cup brown sugar
- 1/2 cup butter (melted)
- 1 cup flour
- 2 eggs
- 1 tsp vanilla
- 1/2 tsp baking powder
- Pinch of salt
How to make Buttery Brown Sugar Cake Squares
Step 1: First things first, get your oven ready. Preheat it to 350°F (175°C). Lightly grease an 8×8 inch baking pan to prevent the cake squares from sticking.
Step 2: In a medium mixing bowl, pour in the melted butter and the brown sugar. Stir them together with a spatula or spoon until the mixture is smooth and well combined. It should look like a glossy caramel paste.
Step 3: Now it’s time for the eggs. Add them one at a time, making sure to mix thoroughly after each one. This helps emulsify the batter and create that perfect chewy texture.
Step 4: Stir in the vanilla extract until it’s fully incorporated. The aroma alone is heavenly!
Step 5: In a separate, smaller bowl, whisk together the all-purpose flour, baking powder, and pinch of salt. Combining the dry ingredients first ensures they are evenly distributed throughout the batter.
Step 6: Gradually add the dry ingredients to your wet mixture. Stir gently until everything is just combined. Be careful not to overmix! Overmixing can develop the gluten in the flour, resulting in tough, dense squares instead of tender ones.
Step 7: Pour the finished batter into your prepared baking pan and use a spatula to spread it into an even layer.
Step 8: Bake for 25 to 30 minutes. You’ll know it’s done when the edges are golden brown and a toothpick inserted into the center comes out clean or with a few moist crumbs attached.
Step 9: This might be the hardest part! Let the cake cool completely in the pan before you attempt to cut it into squares. This allows it to set properly, ensuring clean, neat cuts.
How to serve Buttery Brown Sugar Cake Squares

These cake squares are absolutely delicious on their own, served at room temperature with a hot cup of coffee or a cold glass of milk. For an extra-special dessert, try serving them slightly warm with a scoop of vanilla bean ice cream and a drizzle of caramel sauce. They also make a great base for a simple fruit topping, like fresh berries and a dollop of whipped cream.
How to store Buttery Brown Sugar Cake Squares
To keep your cake squares fresh and chewy, store them in an airtight container at room temperature. They will stay delicious for up to three days. If you prefer, you can also store them in the refrigerator, which will make them a bit firmer. They can also be frozen for up to three months. Just wrap them tightly in plastic wrap and then place them in a freezer-safe bag.
Tips to make
Do Not Overmix: The most important tip for achieving that perfect chewy, tender texture is to mix the flour in until it’s just combined. A few streaks of flour are okay; the batter will come together as you pour it into the pan.
Use Room Temperature Eggs: While the recipe is forgiving, using room temperature eggs helps them incorporate more smoothly into the batter, creating a more uniform texture.
Let Them Cool: I know it’s tempting to dig in right away, but allowing the cake squares to cool completely is crucial for getting those clean, perfect square shapes. Patience is a virtue!
Get Creative with Add-ins: Feel free to customize these bars! A cup of chocolate chips, toffee bits, or chopped nuts can be a fantastic addition. If you enjoy nutty dessert bars, our Brown Butter Pecan Pie Bars are another fan favorite.
FAQs About Buttery Brown Sugar Cake Squares
Can I use dark brown sugar instead of light brown sugar?
Absolutely! Dark brown sugar contains more molasses, which will give your cake squares a deeper, richer caramel flavor and a slightly darker color. Both options are delicious.
Can I double this recipe?
Yes, you can easily double the ingredients and bake it in a 9×13-inch pan. You may need to increase the baking time by 5-10 minutes, so keep an eye on it and use the toothpick test to check for doneness.
Why did my cake squares turn out dry?
The most common reasons for dry cake squares are overbaking or overmixing the batter. Be sure to pull them from the oven as soon as a toothpick comes out clean and only mix the flour until it’s just barely incorporated.
