Ingredients

2 sticks unsalted butter, at room temperature, plus more for the baking dish

3/4 cup light brown sugar

3/4 cup granulated sugar

1 teaspoon vanilla extract

1/2 teaspoon almond extract

2 large eggs

2 tablespoons whole milk

2 1/4 cups all-purpose flour

1 teaspoon baking soda

1 teaspoon kosher salt

1/2 cup rainbow sprinkles

Optional Mix-Ins:

1 cup chocolate, white chocolate or butterscotch chips

1 cup chopped nuts, such as almonds, walnuts, pecans

Optional Decorations:

Icing, edible sugar pearls, sanding sugar, for decorating

Directions

  1. Preheat the oven to 375 degrees F. Prepare a 9- by 13-inch baking dish by coating it with butter.
  2. Combine the butter, brown sugar and granulated sugar in a large bowl. Beat with an electric mixer until light and fluffy, 3 to 4 minutes.
  3. Scrape down the sides of the bowl and beat in the extracts. Add the eggs, one at a time, beating well after each addition. Add the milk and beat again until smooth.
  4. In a separate bowl, whisk together the flour, baking soda and salt. Add half of the flour mixture to the wet ingredients and gently mix to incorporate. Add the remaining flour and mix again. Stir in the rainbow sprinkles and any additional mix-ins you choose.
  5. Spread the batter into an even layer in the prepared pan. Bake until just set in the center, 20 to 25 minutes. Cool on a rack before slicing and decorating as desired.
