7 quart crockpot, can I double this recipe?

I’m making crockpot hot chocolate this weekend, and I’m planning on doubling this recipe. Would it be okay to put it all in my 7 quart crockpot, or should I do the second batch in a separate crockpot? The second one is also a 7 quart. I’d like to save counter space if possible because it’s very limited, and less dishes would be a bonus too lol
