Bear consuming almost every bun? (7)
I believe the answer is:
teacake
'bun?' is the definition.
(I've seen this before)
'bear consuming almost every' is the wordplay.
'bear' becomes 'take' ('take' can be a synonym of 'bear'**).
'consuming' indicates putting letters inside.
'almost' means to remove the last letter (most of the word but not all of it).
'every' becomes 'each' ('each' can be a synonym of 'every').
'each' with its final letter removed is 'eac'.
'take' going around 'eac' is 'TEACAKE'.
(Other definitions for teacake that I've seen before include "Light fruit bun" , "Kind of currant bun" , "Sweet thing" , "Sweet bun" , "Fruited bun" .)
