Ingredients You’ll Need
Getting started with this Creamy Strawberry Banana Jello Recipe is incredibly simple because it relies on a handful of essential ingredients. Each one plays a crucial role—from the bold strawberry flavor to the perfect balance of creaminess and tartness that makes this dish truly unforgettable.
- Strawberry Jell-O package: This is the foundation of the dessert, providing that iconic strawberry flavor and vibrant red color.
- Boiling water: Necessary to dissolve the Jell-O powder thoroughly, ensuring a smooth base.
- Frozen strawberries: They add texture and deepen the fresh berry flavor without making the dessert watery.
- Banana: Adds natural sweetness and creaminess when mashed, complementing the strawberry perfectly.
- Lemon juice: Helps balance sweetness with a hint of tang and brightens the overall flavor profile.
- Sour cream: The secret ingredient that brings that silky, creamy texture and rich tang to this Jello recipe.
- Fresh strawberries (optional): Ideal for garnish, adding a fresh, juicy burst and enhancing presentation.
How to Make Creamy Strawberry Banana Jello Recipe
Step 1: Dissolve the Jello
Start by emptying the 6-oz package of strawberry Jell-O into a large bowl. Carefully pour 2 cups of boiling water over it, then stir until every bit of powder dissolves completely. This ensures the base is smooth and ready to mingle with the other fresh flavors.
Step 2: Add the Frozen Strawberries
Next, toss in 24 ounces of frozen strawberries—whole or sliced, whichever you prefer. Stir the berries into the warm Jello until they are mostly thawed. This adds a wonderful texture and chewy bits that make each bite more interesting. Once mixed, pour everything into a large blender to prepare for the creamy blend.
Step 3: Mash Banana with Lemon Juice
In a small bowl, roughly mash one banana with 2 tablespoons of fresh lemon juice. The lemon juice keeps the banana bright and fresh-tasting rather than dull or brown. Add this mixture to the blender along with the strawberry Jello blend for a beautiful marriage of fruity flavors.
Step 4: Blend in the Sour Cream
Pour in 2 cups of sour cream, either light or regular depending on your preference for richness. Blend everything together for about 30 seconds. Don’t worry if there are a few lumps – that natural texture only adds charm and a homemade feel to your dessert.
Step 5: Prepare Your Mold or Bowl
Grab your favorite Jello mold or a 10-12 cup bundt pan and spray it with nonstick cooking spray to make removal easier. If you prefer to serve it straight from a pretty serving bowl, no need to spray—this dessert is as charming as it is delicious either way.
Step 6: Chill Thoroughly
Pour the creamy mixture into your prepared mold or bowl. Cover it tightly with plastic wrap and place it in the refrigerator for several hours, or ideally overnight. This chilling time lets the flavors meld and the texture set to that perfect creamy firmness we all love.
Step 7: Unmold with Care
When it’s time to serve, place a plate on top of the mold and carefully flip it over. If the jello doesn’t release right away, dip the bottom of the mold in hot water for 1 to 3 seconds. This warms the outer edge just enough to loosen it without melting your creamy masterpiece.
Step 8: Add Final Touches and Serve
Finally, garnish your Creamy Strawberry Banana Jello Recipe with fresh strawberries or any other fruit you love. Slice and serve chilled for the fullest flavor and freshest texture.
How to Serve Creamy Strawberry Banana Jello Recipe

Garnishes
The simplest way to add even more charm to your creamy dessert is with fresh strawberry slices strategically placed on top. They add burst of juiciness, a pop of natural color, and a fresh aroma that intensifies the whole experience. You can also sprinkle a little fresh mint or even a few banana chips for crunch.
Side Dishes
This dessert pairs wonderfully with light mains such as grilled chicken or fish, especially when served at a summer picnic or brunch. For a sweeter combo, fresh fruit salads, whipped cream, or vanilla ice cream on the side will elevate your Creamy Strawberry Banana Jello Recipe to a decadent new level.
Creative Ways to Present
Want to wow your guests? Try layering the Jello with whipped cream or alternating with slices of fresh fruit in a glass trifle dish for a stunning, multi-layered look. You can also mold individual servings in small ramekins for cute, personal desserts perfect for parties.
Make Ahead and Storage
Storing Leftovers
Keep your leftovers tightly covered in the refrigerator, ideally in an airtight container or wrapped well with plastic wrap. The Creamy Strawberry Banana Jello Recipe stays fresh for up to 3 days, maintaining its luscious texture and vibrant flavor.
Freezing
While you can freeze Jello, it’s generally not recommended for this creamy version because freezing may alter the texture and cause separation. For the best experience, enjoy it fresh from the fridge instead.
Reheating
This dessert is designed to be served cold and refreshing, so reheating is not suitable. Just make sure to take it out of the fridge about 10 minutes before serving to allow a slight softening for the best mouthfeel.
FAQs
Can I use fresh strawberries instead of frozen?
Absolutely! Fresh strawberries work wonderfully if in season, but frozen berries help maintain texture and chill the mixture as you blend, making the process quicker and easier.
Is there a dairy-free alternative for the sour cream?
You can substitute with coconut cream or a dairy-free yogurt to keep that creamy texture while accommodating dietary needs, though it will slightly change the flavor profile.
Can this recipe be made sugar-free?
Using a sugar-free strawberry gelatin and choosing a no-sugar-added sour cream can help reduce sugar, but the natural sweetness of the fruit also contributes, so taste and adjust accordingly.
How long does it take to set in the fridge?
For the best firm yet creamy set, plan on chilling the jello for at least 4 hours, though overnight is ideal for maximum flavor melding and texture.
What if the jello doesn’t come out of the mold?
Don’t worry! A quick dip of the mold bottom in hot water for a few seconds will loosen it nicely. Just be careful not to leave it in too long to avoid melting the edges.

Ingredients
Jello and Fruit
- 1 6-oz package Strawberry Jell-O
- 2 cups boiling water
- 24 ounces frozen strawberries (whole or sliced)
- 1 banana
- 2 tablespoons lemon juice
Dairy
- 2 cups sour cream, light or regular
Garnish (Optional)
- Fresh strawberries
Instructions
- Dissolve Jello: Empty the strawberry Jell-O package into a large bowl. Carefully pour 2 cups of boiling water over the jello powder, stirring constantly until the gelatin is completely dissolved and the mixture is smooth.
- Add Frozen Strawberries: Stir in the 24 ounces of frozen strawberries until they begin to thaw and are mostly blended into the gelatin. Then, carefully pour the mixture into a large blender.
- Prepare Banana Mixture: In a small bowl, roughly mash the banana along with the 2 tablespoons of lemon juice. This helps prevent the banana from browning and adds brightness to the flavor. Add this mashed banana mixture into the blender with the jello and strawberries.
- Blend with Sour Cream: Add the 2 cups of sour cream to the blender. Blend the entire mixture for about 30 seconds to combine everything. Some small lumps of banana are acceptable for texture.
- Prepare Mold: Spray a Jello mold or a 10-12 cup bundt pan lightly with nonstick spray. Alternatively, you can use a pretty bowl without spraying.
- Chill: Pour the blended jello mixture into the prepared mold or bowl. Cover the mold tightly with plastic wrap and refrigerate for several hours or overnight, until it is completely set and chilled.
- Unmold Jello: To serve, place a plate over the top of the mold and invert it to release the jello. If it does not come out easily, dip the bottom of the mold in hot water for 1-3 seconds to loosen the edges, then invert again.
- Serve: Garnish with fresh strawberries if desired, and serve chilled.
Notes
- For a lighter version, use light sour cream instead of regular.
- You can substitute fresh strawberries if preferred, but frozen strawberries give the dessert a nice texture.
- Ensure the Jello is fully dissolved in boiling water to avoid graininess.
- Mash the banana with lemon juice to maintain its fresh color and add tartness.
- Allow enough time for the Jello to set completely—several hours or overnight works best.
- If the jello is stuck during unmolding, briefly dipping the mold in hot water will loosen it without melting the dessert inside.
