Preheat oven to 350 degrees F.

Melt 1/2 cup of the butter and combine with pound cake mix and 2 eggs. Mix with an electric mixer on medium until ingredients are well blended.

Stir in 1/4 cup apple butter, 1 tablespoon cinnamon, and 1 tablespoon apple pie spice.

Spread onto a greased cookie sheet with short sides (or a 9x13 brownie pan for a slightly thicker bar). Set aside.

Melt the remaining 1/4 cup butter. Soften the cream cheese in a microwave-safe bowl.

Beat the cream cheese, remaining 2 eggs, powdered sugar, melted butter, 1 tablespoon cinnamon, and vanilla with an electric mixer until fluffy (3-5 minutes).

Pour over cake mixture in pan, being sure to spread all the way to the edges.

Drop remaining 1/2 cup apple butter on the batter and use a knife in a swirling motion to drag the apple butter throughout the batter.

Bake for 45 minutes or until golden brown.

Note: The top of these bars is quite "ooey gooey" (technical term) but they are done cooking at 45 minutes. Let them cool before cutting. You can also refrigerate them for easier cutting.
