Chop the thawed broccoli very fine, almost minced. Place in a large bowl.
Add softened cream cheese, grated cheddar, minced garlic, red pepper flakes, salt, and pepper to the bowl.
Using a sturdy fork, mash everything together until fully combined with no white cream cheese streaks visible.
Line a baking sheet with waxed paper. Scoop mixture and roll into balls under 1 inch in diameter. Place on sheet without touching.
Freeze the balls for 3-4 hours minimum, or overnight until completely frozen solid.
Set up breading station with three shallow dishes: coconut flour in first, eggs whisked with cream in second, pork rind crumbs in third.
Pour oil into a deep, heavy pot (4-quart Dutch oven works well). Heat to 350°F, using a candy thermometer to monitor temperature.
Working quickly with frozen balls, roll each in coconut flour, then dip in egg mixture, then coat with pork rind crumbs, pressing gently.
Drop 4-6 breaded balls into hot oil at 350°F. Fry for about 3 minutes, turning occasionally, until deep golden brown.
Remove with slotted spoon and drain on paper towels. Let oil return to temperature between batches.
Let cool for at least 10 minutes before serving to avoid burns from molten cheese center.
