Ingredients

Bars
  • Strawberry Cake Mix Duncan Hines, one 15.25-ounce box, try Betty Crocker or Pillsbury
  • ½ cup unsalted butter very well softened
  • 1 egg large
Frosting
  • 8 ounces cream cheese softened (lite okay)
  • ½ cup butter unsalted, softened
  • 2 ½ cups confectioners’ sugar sifted if it’s particularly lumpy
  • ½ teaspoon vanilla extract
  • Sprinkles optional and to taste

Instructions

Bars
    Cup of Yum
  1. Preheat oven to 350F. Line a 9×13-inch pan with aluminum foil, spray with cooking spray; set aside.
  2. To a large bowl (or to the bowl of a stand mixer using the paddle attachment), add the cake mix, butter, egg, and stir together by hand or beat with a handheld electric mixer on medium-high speed until all ingredients are combined. (Do not use the ingredients listed on the box or follow those directions because you are not making cake; use the ingredients and directions listed in my recipe.) Dough will be thick.
  3. Turn dough out into prepared pan using your fingertips or a spatula to help press it into corners. Press lightly with a spatula to create an even, flat layer. It’ll be on the thiner side.
  4. Bake for about 12 minutes, or until center is set and a toothpick inserted in the center comes out clean or with a few moist crumbs but no batter.
  5. Allow bars to cool in pan on a wire rack for at least 1 hour. Make sure bars are completely cooled before frosting them or the frosting will melt.
Frosting
  1. To the bowl of a stand mixer using the paddle attachment) add the cream cheese, butter, and beat with an electric mixer on high-speedy until fluffy, about 2 minutes.
  2. Slowly add the confectioners’ sugar, vanilla, and beat until smooth and incorporated, about 2 minutes.
  3. Turn frosting out over bars and spread into a smooth, flat layer using a spatula or knife.
  4. Optionally add sprinkles, to taste.

Notes

  • Bars will keep airtight at room temp for up to 5 days or in the fridge for up to 1 week. I’m comfortable storing items with cream cheese frosting at room temp, but if you’re not, store in the fridge noting bars will be more prone to drying out in the fridge.
