We made peanut butter and jelly muffins last night (I know! Yum!), and it was an exercise in hilarity for Josh and me.
You have to make the peanut butter batter, then push a little hole into the center of the muffin, spoon in the jelly, and then put another glob of peanut butter batter on top. We got Gabe involved, and these were the comments that came out of our mouth, complete with uncontrollable snickering from Gabe's parents.
"You push your fingers in the hole and spread it."
"After you put your fingers in the hole, Daddy will stick the jelly in."
"Stop licking your fingers after putting them in the hole."
"It's too sticky in there."
"You stick your fingers in the middle, not on the sides."
And on, and on, and on.
This is a public service announcement, do not try to accomplish any cooking project like this with preteens or teenagers. It will not go well, I promise you that.
