What you are aiming for — a Key Lime Pie Lemonade off the board. The stand's Medium is 218 calories; this version comes in at 218.
A Key Lime Pie Lemonade is a lemonade build. Key lime pie in a cup is lime plus vanilla cream plus a biscuit note. Graham cracker dusted on the cream is what sells it — the pie reference is mostly texture and smell.

Ingredients
- 120 ml fresh lemon juice (about 4 lemons)
- 150 ml simple syrup
- 400 ml cold water
- 2 tbsp key lime syrup and 1 tbsp vanilla cream
- a lime wheel and a biscuit crumb
- Ice
Equipment
- Citrus juicer
- 1 L pitcher
- Fine-mesh sieve
- 16 oz glass
How to make it
- Juice about 4 lemons until you have 120 ml, then strain it to remove pulp and pips.
- Make the base: dissolve the sugar in 150 ml of just-boiled water, let it cool, then combine with the lemon juice and 400 ml of cold water. Chill at least 30 minutes.
- Put the fruit in the bottom of a 16 oz glass and muddle lightly — press just enough to release juice, not enough to shred it.
- Fill the glass with ice and pour 240 ml of the lemonade base over it.
- Stir in 2 tbsp key lime syrup and 1 tbsp vanilla cream. Taste and adjust: more syrup for sweet, a squeeze more lemon for tart.
- Add a lime wheel and a biscuit crumb and serve immediately while the ice is still hard.
Tips that actually matter
- Graham cracker crumb on the cream — that is the pie reference.
- Key lime is sharper than regular lime; use about two thirds as much.
- The vanilla cream float goes on last so it clouds down slowly.
Variations
- Frozen key lime pie lemonade blended with ice.
- Add 1 tsp of coconut for a tropical key lime.
- Skip the cream for a straight key lime lemonade.
