Ingredients You’ll Need

- 16 ounces coconut water, chilled

- 1 can (14 ounces) sweetened condensed milk
- Ice, for serving

The original recipe uses a mini seedless watermelon, chilled coconut water, fresh lime juice, and a full 14-ounce can of sweetened condensed milk.
How to Make Backporch Punch
1. Prepare the Watermelon
Cut the watermelon in half and remove the rind.
Cut the flesh into large cubes. If you’re using a seedless watermelon, you can add the cubes directly to the blender.
For the coldest punch possible, refrigerate the watermelon before preparing the drink.
2. Add the Fruit and Coconut Water
Place the watermelon cubes in a large, high-powered blender.
Pour in the chilled coconut water and add the juice of one fresh lime.
Start with one lime and taste later. If you prefer a brighter, more tangy flavor, add the juice of a second lime.
3. Blend Until Smooth
Blend on high for approximately 2 minutes.
Give the mixture enough time to become smooth. Proper blending helps break down the watermelon so the drink isn’t overly pulpy.
If your blender is small, work in batches rather than overfilling it.
4. Add the Sweetened Condensed Milk
Pour the entire can of sweetened condensed milk into the watermelon mixture.
Blend again for about 30 seconds, or until everything is completely combined.
The punch will turn lighter and creamier as the condensed milk blends with the watermelon and coconut water.
5. Taste and Adjust
Taste the punch before serving.
If it needs more brightness, add another squeeze of lime. If you prefer a slightly less sweet drink, you can dilute it with a little additional chilled coconut water.
6. Chill
Pour the finished punch into a large pitcher.
Refrigerate until thoroughly chilled, or serve immediately over plenty of ice.
For the best flavor, make sure your watermelon and coconut water are already cold before blending.
7. Serve
Fill glasses with ice and pour the Backporch Punch over the top.
Garnish with a small watermelon wedge, lime slice, or fresh mint.
Serve immediately.
Tips for the Best Backporch Punch
Start with cold ingredients
This is one of the easiest ways to make the drink refreshing without relying on excessive ice.
Chill the watermelon, coconut water, and condensed milk before blending whenever possible.
Use ripe watermelon
The watermelon provides most of the fruit flavor, so choose one that’s ripe and naturally sweet.
A flavorful watermelon means you won’t need to add extra sugar.
Don’t skip the lime
Watermelon and condensed milk are both sweet. Fresh lime juice provides acidity that balances the sweetness and keeps the punch from tasting too heavy.
Strain it if you prefer
For an especially smooth, juice-like drink, pour the blended watermelon and coconut water mixture through a fine-mesh strainer before adding the condensed milk.
This is optional—the punch is delicious with some natural watermelon pulp as well.
Adjust the consistency
For a thicker, creamier punch, use slightly less coconut water.
For a lighter, more drinkable punch, add a little more coconut water.
Delicious Variations
Coconut-Lime Backporch Punch
Add a little extra lime juice and garnish each glass with fresh lime and coconut flakes.
Watermelon Mint Punch
Blend a small handful of fresh mint leaves with the watermelon for a cool herbal note.
Strawberry Watermelon Punch
Replace a portion of the watermelon with fresh strawberries for extra berry flavor and color.
Pineapple Watermelon Punch
Add 1–2 cups of fresh or canned pineapple for a tropical variation.
Sparkling Watermelon Punch
For a lighter, fizzy version, add chilled sparkling water to each glass immediately before serving.
Creamy Berry Punch
Blend a handful of strawberries, raspberries, or blueberries with the watermelon.
Adult Version
For adults who want a cocktail version, the original recipe suggests adding a splash of white rum, coconut rum, or silver tequila just before serving.
What to Serve With Backporch Punch
This fruity punch pairs especially well with summer foods such as:
- Grilled chicken
- Burgers
- Hot dogs
- Barbecue
- Grilled vegetables
- Fresh fruit platters
- Pasta salad
- Coleslaw
- Sandwiches
- Chicken skewers
- Picnic snacks
It’s also a great drink for backyard parties, pool gatherings, picnics, brunches, and casual family get-togethers.
Make-Ahead Instructions
You can prepare Backporch Punch a few hours before serving.
Blend everything together and transfer it to a covered pitcher. Refrigerate until you’re ready to serve.
Because the watermelon and condensed milk can naturally separate while sitting, give the punch a good stir or shake before pouring.
For parties, prepare the punch shortly before guests arrive and keep it chilled until serving.
How to Store Leftovers
Store leftover Backporch Punch in a covered pitcher or airtight container in the refrigerator.
It is best consumed within 2 days.
The mixture may separate during refrigeration, so stir thoroughly before serving again.
For the best texture, don’t freeze the finished punch.
Frequently Asked Questions
Can I use regular watermelon instead of a mini watermelon?
Yes. Any ripe, seedless watermelon will work. You simply need enough watermelon flesh to create the proper balance with the coconut water and condensed milk.
Can I make Backporch Punch without coconut water?
Yes. You can substitute chilled regular water or another mild fruit juice, although coconut water contributes to the original flavor and consistency.
Can I make it less sweet?
Yes. Start by using less sweetened condensed milk, then add more if needed. You can also dilute the finished punch with additional coconut water.
Can I make this without sweetened condensed milk?
You can, but the drink will no longer have the same creamy sweetness. For a lighter version, you could omit it and sweeten the watermelon mixture to taste.
Can I strain the watermelon?
Absolutely. Straining is optional but gives you a smoother, more juice-like beverage.
Can I make it ahead for a party?
Yes. Prepare it earlier in the day, refrigerate it, and stir thoroughly immediately before serving.
