Some desserts just have that magic—where one bite turns into another, and suddenly, the whole pan is gone. These strawberry white chocolate gooey bars are exactly that kind of treat. They’re rich, buttery, and perfectly sweet, with the nostalgic taste of strawberry cake and the creamy indulgence of white chocolate. And the best part? They’re ridiculously easy to make, thanks to a simple cake mix base and a few pantry staples.
The first time I made these… what a disaster!
I remember the first time I attempted these bars. I was in a rush, trying to make a last-minute dessert for a friend’s birthday. I had all the ingredients, but I didn’t read the instructions carefully (rookie mistake). Instead of setting aside part of the dough for the topping, I pressed the whole thing into the pan. I didn’t realize my mistake until I poured the sweetened condensed milk over the top and had no dough left to cover it. I tried to scrape some off the bottom to sprinkle over the top—let’s just say it was a mess.
Even though they looked like a total baking fail, they still tasted incredible. The gooey layers, the sweet strawberry flavor, and those pockets of melted white chocolate chips were enough to make me try again the next day. This time, I followed the instructions properly, and the result? Absolute perfection.
The secret behind these gooey bars
These bars are a spin on classic gooey butter bars, but with a fun strawberry twist. Gooey bars originated from the famous St. Louis gooey butter cake—a soft, chewy, and slightly sticky dessert that’s been around since the 1930s. Over time, bakers started experimenting with different flavors, leading to versions like lemon, chocolate, and now, strawberry white chocolate!
The beauty of these bars is how they balance textures. The bottom layer is soft and chewy, the center is gooey and rich, and the top has just the right amount of crunch from the slightly golden edges. The contrast makes every bite absolutely irresistible.
Let’s talk ingredients: what makes these bars so good?
- Strawberry cake mix – This is the key ingredient that gives the bars their signature flavor and vibrant pink color. If you don’t have a strawberry cake mix, you can use a vanilla or white cake mix and add a few tablespoons of strawberry gelatin powder for a similar effect.
- Unsalted butter – Super soft butter is essential to making the dough come together. If you forget to soften your butter, microwave it in 5-second intervals until just soft.
- Egg – Helps bind everything together. Room temperature eggs work best, so let it sit out for a bit before using.
- White chocolate chips – These add pockets of creamy sweetness. If you’re not a fan of white chocolate, try using semi-sweet or even dark chocolate chips.
- Sweetened condensed milk – This is where the gooey magic happens! It melts into the layers, creating a rich and fudgy texture. If you only have regular sweetened condensed milk, that works just as well.

Kitchen tools you’ll need (and some workarounds)
- 9×9-inch baking pan – This size works best for thick, gooey bars. If you only have an 8×8-inch pan, increase the baking time by a few minutes.
- Electric mixer – Makes beating the butter and dough easier, but you can also use a sturdy spatula and some arm strength.
- Aluminum foil & cooking spray – Lining the pan with foil makes cleanup a breeze. Parchment paper works too, but foil holds its shape better.
- Spatula or greased hands – The dough is thick and sticky, so a spatula helps spread it evenly. Greasing your hands with cooking spray also does the trick.
Step-by-step: how to make these bars perfect every time
- Prep the pan – Preheat your oven to 350°F and line a 9×9-inch pan with aluminum foil. Spray it with cooking spray to prevent sticking.
- Make the dough – Beat the softened butter until smooth. Add the cake mix and egg, then mix until a thick, tacky dough forms. It will look crumbly at first, but keep mixing!
- Press the base layer – Use a spatula (or your hands) to press about two-thirds of the dough evenly into the pan. This forms the chewy foundation of the bars.
- Add the toppings – Sprinkle the white chocolate chips over the dough, then drizzle about 8 ounces of sweetened condensed milk over the top. It might look like a lot, but trust me, it’s what makes these bars gooey.
- Top it off – Take the remaining dough and drop it over the top in small pieces, lightly pressing it down. You don’t need full coverage—some sweetened condensed milk will still be visible.
- Bake to perfection – Bake for 27-30 minutes, or until the edges are golden brown and the center is mostly set (a slight jiggle is okay).
- Cool completely – This is the hardest part! Let the bars cool in the pan for at least 2-3 hours, or overnight for the best results. Cutting them too soon will make a gooey mess.

Fun variations to try
- Chocolate-covered strawberry version – Swap the white chocolate chips for semi-sweet or dark chocolate to create a flavor reminiscent of chocolate-covered strawberries.
- Berry explosion – Add freeze-dried strawberries or a handful of fresh raspberries for extra fruitiness.
- Lemon twist – A teaspoon of lemon zest in the dough brightens the flavor beautifully.
- Gluten-free option – Use a gluten-free cake mix for an easy gluten-free treat.
- Holiday edition – Add red and white sprinkles for Valentine’s Day, or mix in crushed peppermint for a festive Christmas version.
How to serve these bars for maximum deliciousness
These bars are already stunning with their pink hue and gooey layers, but you can take them up a notch with a few finishing touches:
- Dust with powdered sugar – A light dusting makes them look extra fancy.
- Top with whipped cream – A little dollop balances the sweetness perfectly.
- Serve warm with ice cream – Strawberry or vanilla ice cream makes these bars next-level indulgent.
What to drink with these gooey bars?
- Milk – Classic and perfect for cutting the sweetness.
- Coffee – A hot cup of black coffee contrasts beautifully with the rich bars.
- Sparkling rosé – If you’re feeling fancy, this lightly sweet wine complements the strawberry flavor perfectly.
Storing and reheating tips
- Room temperature – Store in an airtight container for up to 4 days.
- Fridge – Keeps well for up to a week. Let them come to room temp before eating.
- Freezer – Freeze for up to 3 months; thaw overnight before enjoying.

FAQs
1. Can I use a different cake mix flavor?
Yes! Vanilla, lemon, or even funfetti cake mix all work well.
2. Why are my bars too runny?
They probably needed more cooling time. Let them sit for a few hours before cutting.
3. Can I double the recipe?
Yes, but use a 9×13-inch pan and increase the baking time slightly.
4. Can I make these without white chocolate?
Absolutely! Try milk or dark chocolate for a different flavor.
5. Do these bars need to be refrigerated?
No, but they stay fresher longer if stored in the fridge.
