Preheat your oven to 325 degrees.
In a large bowl, cream the butter and sugar together until light and fluffy (approximately 5 minutes).
Add the vanilla and almond extracts.
Add the eggs one at a time, mixing just until combined.
In a separate bowl combine the gluten free flour, baking powder, and salt.
Add the dry mixture to the batter, alternating with sour cream, beginning and ending with the dry mixture.
Pour your batter evenly into your prepared 12 c bundt pan.
Bake for 1 hour and 15 minutes or until the cake is golden brown. (Insert a wooden toothpick into the center of the cake. The cake is done when the toothpick comes out clean.)
Allow the cake to cool for 10 - 15 minutes before removing it from the pan.
