AI am making my father-in-law birthday cake and he is a gardener. I am making the vegetable garden and I would like to use the Oreo cookie crumbs for the soil, but the cake is lemon and I am going to create the grass around the soil made with lemon icing. I don't know how the chocolate and the lemon will taste. Does anyone have any sugestions? Please help.

Chocolate and orange is delicious, but not a fan of chocolate and lemon.  However I doubt that the little bit of chocolate cookie decoration on the top will make that much difference in the flavor.

How about crushing up gingersnap cookies. I think that would taste good with the lemon and give you a light brown soil.

AThat does sound better than chocolate. I will keep it in mind. What do you all think about creating a cart with brown fondant and putting the soil in it and the vegetable. That means that non of the soil would touch to cake because the fondant cart will sit directly on the cake.

AChocolate and lemon is not a mainstream flavor, but it is not an unheard of combination either. You are using it as a decoration element, not as a main flavor filling. If you are looking for that black soil decoration element, I wouldn't fret too much. If you don't want the cream flavor of Oreo to come through and chocolate is ok, chocolate graham crackers or those famous wafers (my personal favorite). Gingersnaps sounds good as well, though.

I would bake my own biscuits, using a brown colouring through the dough, flavour as desired and then crush those up.
