This dessert bar recipe has been a go-to for years—it’s simple, rich, and always a crowd-pleaser. Whether for a party, bake sale, or just a sweet treat at home, these bars have won hearts everywhere.

A Brief History

Dessert bars have been a staple in American kitchens since the early 20th century, evolving from traditional cookies and cakes into a convenient, sliceable treat. Some of the most famous bars—like brownies and blondies—originated from creative bakers looking for an easier way to serve handheld sweets. This recipe follows in that tradition, doubling up on flavor and texture for an irresistible bite.

Ingredients

(Makes one 9×13-inch pan of delicious dessert bars)

Wet Ingredients:

  • 1 cup (2 sticks) unsalted butter, melted
  • 2 cups brown sugar, packed
  • 2 large eggs
  • 2 teaspoons vanilla extract

Dry Ingredients:

  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt

Mix-ins (Choose Your Favorites!):

  • 1 cup chocolate chips (semi-sweet, milk, or dark)
  • 1 cup chopped nuts (walnuts, pecans, or almonds)
  • 1 cup shredded coconut
  • 1 cup butterscotch chips

Instructions

Step 1: Prepare Your Oven and Pan

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or line it with parchment paper for easy removal.

Step 2: Mix the Wet Ingredients

In a large bowl, whisk together the melted butter and brown sugar until smooth. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

Step 3: Combine Dry Ingredients

In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.

Step 4: Mix Everything Together

Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Do not overmix! Gently fold in your choice of mix-ins.

Step 5: Bake to Perfection

Spread the batter evenly into the prepared 9×13-inch pan. Bake for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean.

Step 6: Cool and Serve

Allow the bars to cool in the pan for at least 20 minutes before cutting into squares. Serve warm or at room temperature.
