I stumbled upon this strawberry upside down cake recipe last summer when I had a flat of berries about to go bad, and it's become my go-to dessert for potlucks and backyard BBQs! The combo of fresh strawberries, strawberry jello, and fluffy white cake creates this amazing sweet-tart flavor that tastes way more complicated than the actual effort involved.
My neighbor practically stalked me for this recipe after trying it at our block party last July. When I told her how simple it was, she didn't believe me until I showed her the recipe card!
What You'll Need
- White cake mix: Any brand works fine - I've used everything from Betty Crocker to store brand with good results.
- Fresh strawberries: The star of the show! Ripe, juicy berries work best, but even slightly underripe ones soften nicely during baking.
- Strawberry jello: The powdered mix gets sprinkled right on the berries - no need to make the actual jello first.
- Mini marshmallows: These melt during baking to create a gooey layer between the fruit and cake that's absolutely heavenly.

How I Make It
Smart PrepI've found that using baking spray with flour (like Baker's Joy) works way better than regular cooking spray for preventing sticking. Nothing worse than having half your beautiful strawberry topping stay stuck in the pan when you flip it!
Berry BusinessI quarter large strawberries and halve small ones so they create an even layer. Arranging them cut-side down makes the prettiest top once flipped. Don't pack them too tightly together - leave a little space for the jello to settle between them.
Jello GeniusSprinkling the dry jello powder directly on the berries seems weird at first, but it combines with the natural juices from the strawberries during baking to create this amazing glossy glaze. Make sure to sprinkle it evenly so you don't get overly sweet spots.
Flipping TechniqueAfter cooling for about 20 minutes (no longer!), I place a serving tray or board over the top of the pan, then quickly but confidently flip the whole thing over. Waiting too long makes it harder to release from the pan.
I brought this to a family reunion where three people claimed to "not like strawberries" - and all three went back for seconds! There's something about the baking process that transforms the berries into something so much more than their fresh state.
Serving Ideas
This cake is perfect on its own, but adding a dollop of fresh whipped cream takes it to the next level. For extra indulgence, serve it slightly warm with a scoop of vanilla ice cream. I've even served it as a brunch item alongside coffee - the fruit makes it breakfast-appropriate, right?
Make It Your Own
Try different jello flavors with the strawberries - raspberry or cherry adds depth. Mix berries for a mixed berry version - blueberries and strawberries together are amazing. Add a teaspoon of almond extract to the cake batter for a subtle flavor boost. Sprinkle sliced almonds on the bottom (which becomes the top) before adding the berries for crunch.
Storage Smarts
This cake is actually better the second day when the flavors have had time to meld, but the presentation is best on day one. I store mine in the fridge covered with plastic wrap (not foil, which can react with the berries). It keeps well for about 3 days before the cake starts to get soggy from the fruit juices.

Pro Tips
- If your strawberries aren't very sweet, sprinkle a tablespoon of sugar on them before the jello
- Line the bottom of your pan with parchment for extra insurance against sticking
- For a cleaner slice, use a knife dipped in hot water between cuts
This cake has saved me countless times when I needed a dessert that looks and tastes like I spent hours on it, when in reality it took about 10 minutes of active time! There's something so satisfying about the "ooh" and "ahh" when you reveal those glistening red berries on top—it's the perfect dessert for people who want maximum impact with minimum effort.
Frequently Asked Questions
- → Can I use frozen strawberries instead of fresh?
- Yes, but thaw and drain them thoroughly first to prevent excess moisture that could make the cake soggy.
- → What can I use instead of strawberry jello?
- You can use raspberry or cherry jello for a similar flavor, or try other fruit-flavored jellos to complement different berries.
- → Can I make this cake a day ahead?
- Yes, but it's best served the same day. If making ahead, store in the refrigerator and bring to room temperature before serving.
- → Why did my marshmallows disappear in the cake?
- The marshmallows melt into a sweet, gooey layer during baking. This is normal and creates that special texture between the cake and fruit.
- → How do I know when the cake is done?
- Insert a toothpick into the center of the cake portion - it should come out clean or with a few moist crumbs, but no wet batter.
