In a bowl of a stand mixer (hand mixer works just as well), combine the first 4 ingredients and mix well, until combined and smooth. If you don't want it to be too garlicky use only 2 cloves (3 was a little too strong for my daughter but my husband and I both thought it was great). Fit a piping bag with a large star tip (1M) or a large flower tip (2D) and fill the bag with the cream cheese mixture.
Roughly peel the cucumber, this give it a nicer look but you can definitely skip this step. Slice the cucumber into 1/4 - 1/2 inch discs. Place all the sliced cucumbers on a platter.
Pipe the cream cheese mixture on each cucumber slice and top with Everything but the Bagel Seasoning, a little bit goes a long way.
