Cut a circle in the top of the bread leaving about 1 inch around the edge. Remove the top and tear out the inside of the bread to make room for the dip, leaving about 1-inch wall around the middle and bottom.
Cut slices around the edge of the bread about 1.5 inches apart. Slice about 3/4 of the way, but not all the way through the bottom. This will make pull apart pieces for people to tear off and dip.
Make the beer cheese dip
In a medium bowl, stir cream cheese until smooth. Add the grated cheddar cheese and 1 cup of the grated mozzarella, stir to combine.
Add the garlic powder, beer and hot sauce, stir until completely mixed.
Pour into the prepared bread bowl and sprinkle the remaining ¼ cup of mozzarella on top. Replace top of the bread.
Bake for 20-25 minutes or until cheese is melted and bread is golden.
Garnish with chopped parsley if desired and serve with additional slices of bread and/or crackers for dipping.
Serve in a dish with edges to catch any of the cheese dips that might spill out.
Notes
Use something to catch any dip that might spill out of the bowl like a baking sheet.
You can experiment with the cheeses and different beers for other flavor options.
Try it in a crockpot and serve the dippers on the side.
