Preheat oven to 350 degrees. Grease or spray a standard size bundt pan with oil.
In a medium bowl, whisk together the almond flour, cocoa powder, baking powder, baking soda, xanthan gum and salt.
In a large mixing bowl, use a hand mixer on medium speed to cream together the butter and sweetener. Blend until light and fluffy. Scrape down the sides. Blend in eggs one at a time, scraping down the sides after each. Blend in vanilla. Add Almond flour mixture a little at a time alternating with the sour cream. Blend in the hot coffee until just combined. Gently fold chocolate chips into the batter.
Spoon batter into prepared bundt pan. Gently tap pan on counter to release any air bubbles. Smooth the top evenly with the back of a spoon. Bake cake for 40-45 minutes, until a toothpick or tester inserted in the center comes out with just a few crumbs on it.
Remove the cake from the oven and cool on a wire rack for 10-15 minutes. Gently loosen the sides and invert the cake on cake stand. Allow to finish cooling.
