(*Note- you will need a large saucepan for this recipe, not a mixer and mixing bowl!)
Preheat oven to 350 F (static) or 325°F (convection).
Prepare a 9-inch springform tube or bundt pan or two 8-inch rounds by buttering and dusting lightly with gfJules™ All Purpose Gluten Free Flour.
In a small bowl, whisk the sour cream with the eggs and vanilla.
Measure out 1 cup of beer and let the head settle to be sure your measurement is correct. Pour the beer into a large saucepan (you can drink the rest!). Add the butter and heat just until melted over medium heat.
Whisk in the cocoa powder and the sugar until smooth.
Add the egg mixture into saucepan mixture and whisk. Sift in the the gfJules Flour and baking soda and whisk until mixed.
Pour into the prepared pan and bake for 35-40 minutes, or until a toothpick inserted into the center of the cake comes out fairly clean or with crumbs, not wet. Time will differ depending on the pan, so rely on the toothpick test.
Let the cake cool in the pan on a cooling rack for 15 minutes, then gently invert to remove from pan onto a cake plate.
Once cooled, dust with confectioner's sugar or frost with cream cheese frosting or sour cream frosting.
