20 Refreshing Summer Sonic Drinks to Try

These summer Sonic drinks let you recreate the drive-in's most requested cups without leaving your kitchen, using syrups and sodas you can measure exactly. Every recipe here is an independent copycat built from scratch with real ingredients and ratios, not an order placed anywhere. You control the sugar, the ice, and the strength of every pour, so a jug can go from tart to sweet in seconds. Best of all, most of these drinks come together in under 10 minutes with a blender or a pitcher and a long spoon.

This is the drink most people picture first: fresh lime juice and a dark cherry syrup stirred into cold lemon-lime soda over crushed ice. Simmer 150 g (1 cup) frozen pitted cherries with 100 g (1/2 cup) sugar and 120 ml (1/2 cup) water for 8 minutes, then strain for a clear ruby syrup instead of using bottled grenadine. Pour 30 ml (2 tbsp) of that syrup and the juice of one lime into a tall glass, then top with 240 ml (1 cup) chilled Sprite. Crushed ice, not cubes, is the trick that keeps it slushy-cold without watering it down too fast.

Ocean Water is just three things done well: lemon-lime soda, coconut syrup, and a single drop of blue food colouring. Whisk 120 ml (1/2 cup) sugar into 120 ml (1/2 cup) warm water until fully dissolved, cool it, then stir in 15 ml (1 tbsp) coconut extract to make your own syrup instead of buying flavoured Torani. Pour 20 ml (4 tsp) of that syrup over ice, add one drop of blue gel colouring, and top with 240 ml (1 cup) Sprite. Stir gently from the bottom so the colour swirls through evenly rather than pooling at the base.

This variation pushes the coconut flavour further for anyone who finds the classic Ocean Water too subtle. Use 30 ml (2 tbsp) of the coconut syrup instead of 20 ml, and swap half the Sprite for coconut-flavoured sparkling water so the fizz carries more of the tropical note. Float a thin wheel of fresh lime on top rather than stirring it in, since the oils release slowly and add a citrus lift as you drink. Keep the food colouring to one drop; two turns the drink teal instead of the signature pale blue.

Blend 300 g (2 cups) ice with 60 ml (1/4 cup) sugar water and 15 ml (1 tbsp) vanilla extract until it reaches a fine, sippable slush texture, about 45 seconds on high. Pour the slush into a cup, then drop in one scoop of vanilla ice cream so it floats and slowly melts into the drink rather than mixing straight in. A short 10-second blitz keeps the ice fine; over-blending turns it watery instead of slushy. Serve immediately with a wide straw so the melting ice cream doesn't clog a narrow one.

Blend 300 g (2 cups) frozen watermelon chunks with 60 ml (1/4 cup) lime juice and 30 g (2 tbsp) sugar until completely smooth, then pulse in 8-10 fresh mint leaves for just a few seconds so flecks of green stay visible. Freezing the watermelon beforehand is what gives the slush its thick, spoonable texture without diluting the flavour with extra ice. Taste before serving, since watermelon sweetness varies a lot by season and you may need another 15 g (1 tbsp) sugar. Garnish with a small mint sprig pressed against the inside of the glass.

Brew 480 ml (2 cups) strong black tea and let it cool completely, then stir in 60 ml (1/4 cup) peach syrup and 30 g (2 tbsp) sugar while the tea is still warm so it dissolves fully. Pour over ice and top with a splash of peach nectar for extra body and a soft, ripe-fruit finish. Using cooled tea rather than pouring hot tea over ice keeps the drink from turning cloudy and prevents the ice from melting too fast. A frozen peach slice as garnish also acts as an extra ice cube that won't water the drink down.

Blend 250 g (1 3/4 cups) frozen strawberries with 240 ml (1 cup) lemonade and 100 g (1/2 cup) ice until thick and completely smooth, roughly one minute on high speed. If the slush is too thin, add another 50 g (1/3 cup) ice a little at a time rather than more strawberries, which can make it icy instead of creamy. Strain out the seeds with a fine mesh sieve first if you want a smoother texture like the drive-in version. Finish with a drizzle of extra lemonade poured over the top so the first sip through the straw is tart before the sweet strawberry comes through.

Combine 300 g (2 cups) ice, 90 ml (6 tbsp) blue raspberry syrup, and 120 ml (1/2 cup) cold water in a blender and process until it forms a fine, even slush with no large ice chunks remaining. Blue raspberry syrup is stronger than most fruit syrups, so start with less and add more to taste rather than following flavoured syrup measurements exactly. For an extra-thick texture closer to the drive-in machine version, freeze the syrup and water mixture in ice cube trays first and blend the flavoured cubes instead of plain ice. Serve within a few minutes, since this slush melts faster than fruit-based ones.

For the fastest option on this list, stir 60 ml (1/4 cup) lime juice and 45 g (3 tbsp) sugar into 350 ml (1 1/2 cups) cold sparkling water until the sugar fully dissolves. No cooking or syrup-making is needed, which makes this the one to reach for on a hot afternoon with no prep time. Adjust the sugar in 15 g (1 tbsp) increments depending on how tart your limes are, since bottled juice is usually milder than fresh-squeezed. Pour over ice immediately so the fizz doesn't flatten before serving.

Blend 200 g (1 1/3 cups) frozen mango, 150 g (1 cup) frozen peach slices, and 120 ml (1/2 cup) orange juice until silky smooth, about 45 seconds. This combination copies the tropical, sweet-cream note in Sonic's popular summer slush menu without needing any dairy at all. If the mixture won't move in the blender, add cold water 30 ml (2 tbsp) at a time rather than more juice, which can make it too sweet. A thin drizzle of sweetened condensed milk on top adds the creamy finish some drive-in versions include.

Muddle a 2 cm (3/4 in) piece of fresh ginger with 30 g (2 tbsp) sugar and the juice of one lime in the bottom of a glass until fragrant. Top with 240 ml (1 cup) ginger beer and stir gently, keeping the ice cubes large so they melt slowly and don't dilute the spice too quickly. This one skips the usual lemon-lime soda base entirely, giving it a warmer, slightly peppery finish that pairs well with grilled food. Strain out the muddled ginger pieces before serving if you prefer a smoother sip.

Freeze three separate slush bases ahead of time: a cherry limeade slush, a plain vanilla cream slush, and a blue raspberry slush, each blended to the same fine texture. Spoon them into a clear cup one colour at a time, pressing each layer down gently with the back of a spoon so they stay distinct instead of blending together. Serve straight away with a wide straw so guests can see the three stripes before stirring them into one drink. This one is built for a crowd, so double each base if you're serving more than four people.

This one copies Sonic's seasonal favourite by layering a frozen lemonade slush with vanilla ice cream and real strawberries. Blend 240 ml (1 cup) lemonade with 200 g (1 1/3 cups) ice until slushy, pour it into a tall cup, then top with a scoop of vanilla ice cream and 60 g (1/2 cup) sliced fresh strawberries. Add the fruit last so it sits on top rather than sinking, which keeps the presentation closer to the original triple-layered version. Eat with a spoon for the first few bites before the ice cream melts into the slush.

Blend 300 g (2 cups) ice with 90 ml (6 tbsp) green apple syrup and 15 ml (1 tbsp) lime juice for a tart, bright-green slush that's less common but easy to love. The lime juice is the key swap here; it cuts through the syrup's sweetness so the drink doesn't taste one-note. Add a pinch of citric acid or a splash more lime if you want an extra-sour kick similar to sour candy. This slush holds its texture a little longer than fruit purée versions, so it's a good pick for slower sippers.

Any slush on this list becomes a cream slush with one small change: blend in 30 ml (2 tbsp) half-and-half per 240 ml (1 cup) of slush right at the end, pulsing just two or three times. Adding the cream too early or blending too long will thin the texture instead of giving it that signature velvety mouthfeel. This works especially well with the cherry limeade and blue raspberry versions, softening the tartness without masking the fruit flavour. Keep the cream cold before adding it so the slush doesn't start melting on contact.

Shake 200 ml (3/4 cup plus 1 tbsp) coconut milk, 30 ml (2 tbsp) simple syrup, and 15 ml (1 tbsp) lime juice with ice for 20 seconds, then strain over fresh ice in a tall glass. The shaking step matters here; it emulsifies the coconut milk so the drink pours smooth instead of separating in the glass. Top with a splash of soda water for light fizz, or leave it still for a richer, more dessert-like sip. Toasted coconut flakes pressed onto the rim add crunch and make it look like a proper summer treat.

Take the base cherry limeade recipe from earlier and add a scoop of vanilla ice cream on top instead of extra soda, turning it into a proper float. Pour the limeade first, then lower the ice cream in gently with a spoon so it floats rather than sinking and clouding the drink. The carbonation from the soda keeps bubbling up around the ice cream, which is part of the appeal and why this works better as a float than a shake. Serve with both a straw and a spoon since you'll want to scoop the last bit of melted cream from the bottom.

This one recreates a popular drive-in custom order: Sprite mixed with blue raspberry syrup, a splash of vanilla, and a splash of lemonade. Combine 240 ml (1 cup) Sprite, 20 ml (4 tsp) blue raspberry syrup, 10 ml (2 tsp) vanilla syrup, and 15 ml (1 tbsp) lemonade over ice and stir well. The vanilla is easy to overdo, so measure it rather than free-pouring, since too much turns the drink cloudy and overly sweet instead of balanced. The colour should land somewhere between teal and turquoise; add another drop of blue colouring only if it looks too green.

Blend 240 ml (1 cup) orange juice, 200 g (1 1/3 cups) ice, and 30 ml (2 tbsp) sweetened condensed milk until the texture turns pale and fully smooth, similar to a frozen creamsicle. Condensed milk works better here than half-and-half because its sugar content helps the mixture freeze into a proper slush instead of a thin smoothie. Taste before serving and add a little more orange juice if it tastes too much like straight condensed milk. A thin curl of orange zest on top adds aroma and a nice pop of colour.

Blend 100 g (3/4 cup) peeled cucumber with 30 ml (2 tbsp) lime juice and 15 g (1 tbsp) sugar, then strain through a fine sieve to remove the pulp and keep only the pale green juice. Top the strained juice with 200 ml (3/4 cup plus 1 tbsp) soda water over ice for a light, savoury-sweet drink that's less sugary than the rest of the list. This is the one to make when you want something refreshing but not dessert-sweet, especially alongside spicier grilled food. A thin cucumber ribbon draped over the glass rim makes an easy, elegant garnish.

Use crushed ice rather than cubes for slushes and limeades; it chills the drink faster and gives that signature drive-in texture without needing a machine. Always dissolve sugar into warm liquid before adding cold soda or ice, since sugar won't dissolve properly once everything is chilled. Chill your glasses and syrups ahead of time on hot days so the ice doesn't melt the moment the drink is built. Finally, taste every batch before serving a crowd, since fruit sweetness and syrup brands vary enough to shift the whole balance.

Rim glasses with sugar or a mix of sugar and citrus zest for the fruitier drinks, and with toasted coconut for the tropical ones. Frozen fruit chunks, like grapes or berries, make excellent flavoured ice cubes that won't water down a drink as they melt. Keep straws wide for anything slushy or floated with ice cream, since narrow straws clog almost immediately. For a party, set out small bowls of maraschino cherries, lime wedges, and mint so guests can garnish their own cups.

Homemade syrups keep well in the fridge for up to two weeks in a sealed jar, so make a big batch of cherry, coconut, or blue raspberry syrup once and use it across several drinks all week. Fruit purées and slush bases without soda can be frozen flat in freezer bags for up to two months, then broken up and reblended with a splash of fresh soda when needed. Never batch a drink with soda already mixed in ahead of time, since it goes flat within an hour; always add the fizz last, right before serving. For parties, set out the base mixers in labelled pitchers and let guests build their own cup over ice.
