Ingredients
For the Slab
2 cups all-purpose flour
1 cup granulated sugar
1 teaspoon baking powder
½ teaspoon salt
½ cup butter, softened
½ cup creamy peanut butter
1 large egg
1 teaspoon vanilla extract
½ cup milk
For the Peanut Butter Syrup
½ cup granulated sugar
½ cup packed brown sugar
¼ cup water
¼ cup creamy peanut butter
2 tablespoons butter
½ teaspoon vanilla extract
Pinch of salt
Step 1: Prepare the Baking Pan
Start by preheating your oven to 350°F (175°C).
Grease a 9-by-13-inch baking pan lightly with butter or nonstick cooking spray. For easier removal, you can also line the bottom with parchment paper, leaving a little overhang on two sides.
Set the prepared pan aside while you make the batter.
Step 2: Combine the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, and salt.
Mixing these ingredients separately helps distribute the baking powder evenly throughout the flour. This gives the finished slab a more consistent texture.
Set the bowl aside.
Step 3: Cream the Butter, Peanut Butter, and Sugar
Place the softened butter, peanut butter, and granulated sugar in a large mixing bowl.
Beat everything together until the mixture becomes smooth and creamy. You can use a hand mixer or a sturdy wooden spoon if you prefer to make it by hand.
The peanut butter should be completely incorporated into the butter and sugar, leaving you with a thick, creamy mixture.
Step 4: Add the Egg and Vanilla
Add the egg and vanilla extract to the peanut butter mixture.
Beat until everything is well combined and the mixture looks smooth.
Scrape down the sides of the bowl if necessary so that all of the ingredients are evenly incorporated.
