Measure the dry ingredients and the small bowl
Add the Cake flour, salt, baking soda, and sugar to the small bowl. Set aside
Wet Ingredients go into the mixing bowl
Add the unsalted butter to the mixing bowl and microwave covered for 30 seconds. You want it soft not completely melted
Add the pure vanilla extract, half-n-half, and Greek yogurt. Stir to slightly mix
Heat the 1/2 cup of water for 1 full minute in the microwave and set aside
Add the dry ingredients to the mixing bowl and stir to slightly blend the dry ingredients. This is to keep the dry ingredients from flying out of the bowl when you use the mixer. Then use the immersion whisk to blend the ingredients
Add the hot water and the vinegar to the mixing bowl
Use the immersion blender/mixer to blend the batter. The vinegar and the baking soda will active a rising process
Pour the batter into the cake pan and set into the oven to bake
After 28 minutes, check for doneness using the toothpick process. The cake will continue to cook a little more while resting.
Remove from oven and let rest for 10 minutes before removing from the cake pan and setting on a plate.
