Ingredients

  • 1 ½ cups all-purpose flour
  • 1 ½ teaspoons baking powder
  • ¼ teaspoon salt
  • ½ cup unsalted butter softened
  • 1 cup granulated sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • ½ cup whole milk
  • 1 cup frosting of your choice
  • Assorted toppings sprinkles, chocolate chips, crushed nuts, etc.

Instructions

  • Preheat your oven to 350°F (175°C). Grease the inside of each mason jar with cooking spray or butter and set aside.
  • In a medium mixing bowl, sift together the flour, baking powder, and salt. Set aside.
    1 ½ cups all-purpose flour, 1 ½ teaspoons baking powder, ¼ teaspoon salt
  • In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy using a hand mixer or stand mixer.
    ½ cup unsalted butter, 1 cup granulated sugar
  • Add the eggs one at a time, beating well after each addition. Then, mix in the vanilla extract.
    2 large eggs, 2 teaspoons vanilla extract
  • Gradually add the dry ingredients to the wet ingredients, alternating with the milk, starting and ending with the dry ingredients. Mix until just combined, being careful not to overmix.
    ½ cup whole milk
  • Divide the batter evenly among the prepared mason jars, filling each jar about halfway full.
  • Place the filled mason jars on a baking sheet and transfer them to the preheated oven. Bake for 25-30 minutes, or until a toothpick inserted into the center of a cake comes out clean.
  • Remove the jars from the oven and allow them to cool completely on a wire rack.
  • Once cooled, spread a layer of frosting on top of each cake in the jar. Add your favorite toppings to decorate.
    1 cup frosting of your choice
  • Screw the lids onto the jars and store in the refrigerator until ready to serve. Enjoy your adorable and delicious cake in a jar!

Notes

  • Don't overmix the batter. This helps keep the cake light and fluffy.
  • Only fill each jar halfway! This will keep it from baking over the top.
  • Don't want to make homemade frosting? Use your favorite canned frosting, but make it better!
  • Use 16 ounce mason jars for this recipe.
