You dont get the buckets back when you make cake

You dont get the buckets back when you make cake.

I was expecting to get the 3 buckets back after I made the cake.

When I made it though, I didnt get the buckets back I dont know if this was intended but its not fair if it was.

Steps to Reproduce:
1.Go to crafting table
2. Make a cake
3. You wont get the buckets back
