Malted bday Cake

1. - preheat oven to 350F
2. - grease 9x13 inch baking pan with veg oil
3. - bring cold ingredients to room temp
4. MAKE THE CAKE BATTER
5. • Combine the milk and 1 tablespoon plus 1 ½
6. teaspoons white vinegar and let sit until thickened and curdled.
7. • Whisk to combine 2 ¼ cups flour, ¾ cup malted milk powder, ¼ cup cornstarch, 1
8. ¾ teaspoons baking powder, ¾ teaspoon baking soda, and
9. 2 ¼ teaspoons salt in a medium bowl.
10. • Combine 1 ½ sticks butter and 1 ⅔ cups granulated sugar in the bowl of a stand mixer fitted with a paddle attachment. Beat on medium-high until lightened, scraping down the bowl once or twice, 3-4 minutes.
11. • Add ¼ cup vegetable oil, 1 tablespoon plus 2 teaspoons vanilla extract, and the eggs.
12. Beat at medium speed until smooth, working up to medium-high, scraping down the bowl, about 2 minutes.
13. Add the milk mixture and mix until combined. The batter will look curdled at this point and that's okay!
14. • Add the dry ingredients and mix until no floury bits remain and batter is nearly smooth (there may be some lumps), scraping down the sides of the bowl as necessary.
15. • Transfer to the prepared pan, smooth the top, and bake, rotating halfway through, until lightly golden on top and a toothpick comes out clean, about 38-42 minutes.

3. WHILE THE CAKE BAKES, MAKE THE BUTTERCREAM:

1. • Sift 2 cups powdered sugar and the remaining 1 cup plus 2 tablespoons malted milk powder into the stand mixer bowl.
2. • Add the remaining 3 sticks butter (make sure they're quite soft for the smoothest frosting) and beat, starting on low speed and gradually increasing to medium-high, scraping down the bowl until lightened and smooth, about
3. 2-3 minutes.
4. • Add the remaining 3 tablespoons milk, the remaining 1 tablespoon vanilla, and ½ teaspoon salt. Beat to combine. Adjust consistency as necessary in teaspoons with more milk. Season to taste with salt.
5. • Once cooled, frost the cake, decorate it as you wish and serve it up.
