The Key Lime Pie is one of the most unique drinks on the 7 Brew menu. Lime and lemon give it a strong, tart citrus taste. White chocolate adds a creamy sweetness, like the filling and whipped topping of a pie. Because of the white chocolate, it contains milk. A Large iced Key Lime Pie has about 420 calories.
White chocolate in lemonade sounds strange, but it works. It softens the sour citrus and gives the drink a dessert feel. Make sure to stir well, because the sauce can sink. A crushed graham cracker rim makes it taste even more like pie. It is a fun drink for spring and summer.

Ingredients for the 7 Brew Key Lime Pie Recipe
Here is everything you need for this 7 Brew Key Lime Pie recipe. It makes one 16-ounce drink, which is close to a 7 Brew Small. Use coffee-shop style syrups and sauces, the same kind sold for lattes and Italian sodas. A pump from a store syrup bottle is about 1/4 ounce, and a tablespoon is about 1/2 ounce. Change the amounts after your first try to match your taste.
| Ingredient | Amount | Notes |
|---|---|---|
| Lemonade | 1 cup (8 oz) | Store-bought or homemade |
| Lime syrup | 1/4 oz (1/2 tbsp) | Or 1 tbsp fresh lime juice |
| Lemon syrup | 1/4 oz (1/2 tbsp) | Extra citrus |
| White chocolate sauce | 1/2 oz (1 tbsp) | Creamy pie flavor |
| Ice | 1 to 1 1/2 cups | Crushed or nugget ice works best |
Tip: Warm the white chocolate sauce for 10 seconds and whisk it into a little lemonade first. That keeps it from clumping in the cold drink.

Flavored lemonades at 7 Brew are quick to copy. Mix the syrups into the lemonade first so the flavor spreads evenly. Then pour it over a cup full of ice. Stir well and taste. The whole drink takes about three minutes.
1. Mix the flavors
Stir the lime syrup, lemon syrup and white chocolate sauce into 1 cup of cold lemonade.
2. Fill a cup with ice
Add about 1 1/2 cups of ice to a 16 oz cup.
3. Pour and stir
Pour the flavored lemonade over the ice and stir.
4. Garnish
Add a lemon slice or fresh fruit if you like.
Dip the rim of your cup in honey, then in crushed graham crackers. Fill with ice and pour in the lemonade. Top with whipped cream and lime zest for a real pie look. If it is too tart, add more white chocolate. If it is too sweet, add fresh lime.

Common Mistakes When Making a Key Lime Pie
- Too much syrup: start small, because you can always add more.
- Warm ingredients: they melt the ice and water the drink down.
- Skipping the stir: syrup sinks, so the last sips taste too sweet.
- Wrong cup size: a 16 oz cup keeps the flavor balance right.
