Prepare Bundt cake pan by spraying with non-stick baking spray.
In a large bowl, whisk together flour, ground ginger, ground cinnamon, ground nutmeg, salt, baking soda and baking powder. Set bowl aside.
2 ½ Cups All Purpose Flour, 1 Tablespoon Ground Ginger, 1 teaspoon Ground Cinnamon, 1 teaspoon Ground Nutmeg, 1 teaspoon Salt, ¼ teaspoon Baking Soda, 1 teaspoon Baking Powder
In a separate large bowl, beat the brown sugar and butter together until light and fluffy (1 - 3 minutes). A stand or hand mixer may be used.
¾ Cup Unsalted Butter, 1 ½ Cups Dark Brown Sugar
Add the eggs one at a time, mixing between each addition.
2 Large Eggs
Add molasses and mix until well combined.
½ Cup Molasses
Add flour mixture to the mixing bowl in three additions, alternating with the water (starting and ending with the flour).
1 Cup Water
Pour one-half of the cake batter into Bundt pan. Using a spatula or spoon, create a well through center of the batter. Pipe or spoon lemon cream cheese filling into the well.
Pour remaining half of cake batter over the filling. Smooth top of the batter with a rubber spatula.
Bake for 55 - 60 minutes, or until a toothpick inserted in the center of the cake comes out clean.
Remove pan from oven and place on a cooking rack for 15 minutes. After 15 minutes invert the pan onto the cooling rack and allow to cool completely (approximately 1 hour).
