Preheat oven to 350*. Grease and flour baking pan. Set aside.

In bowl, mix eggs, yolk, buttermilk, oil, & vanilla. Mix well. It’ll be a tad foamy.

Sift ALL dry ingredients together. Stir into egg mixture.

SLOWLY pour in HOT water, once water is combined, continue mixing on low speed for 1 minute. Batter will be soupy!

Pour into prepared pan, jiggle pan to evenly distribute.

Bake 45 - 55 minutes or until cake tester inserted comes out clean.

Remove from oven, let sit in pan10 minutes. Invert onto wire rack to room temp. Store in airtight container.

This so yummy by itself, it’s even better with a big scoop on vanilla ice cream!
