Preheat oven to 350 degrees F.
Lightly grease and flour a standard size bundt pan.
In a medium size bowl, add buttermilk, yogurt, and vanilla and whisk until blended.
In a large bowl, add brown sugar, honey, and butter. Using your hand mixer, blend until light and fluffy, about 2 minutes.
Add molasses and continue to blend.
Add eggs, one a time and blend all of the ingredients until well incorporate.
Next, add 1/3 of the flour mix plus 1/3 of the buttermilk, yogurt, vanilla mixture to your bowl.
Blend these ingredients and repeat the step above until all of the flour and liquids are blended.
Pour batter into prepared bundt pan.
Tap on the counter to remove any bubbles and then bake for 50 to 60 minutes or until a toothpick inserted in the center comes out clean.
Remove the cake when done and allow to cool for an hour.
Carefully remove from bundt ban and frost.
For the glaze, mix about a cup of powdered sugar with a couple tbsp heavy cream or half and half. You want your glaze to be thick and not too runny so adjust the liquid - sugar ratio as needed.
