I’m obsessed with these Strawberry White Chocolate Gooey Bars because they taste like Valentine’s Day got a little messy and way more fun. I love the soft, chewy bite, the sweet strawberry flavor from strawberry cake mix, and those creamy little hits of white chocolate chips in every square.

But the real reason I keep coming back? That gooey middle.

Sticky, rich, ridiculous. And so pretty without trying too hard.

I like desserts that look cute but still taste bold, and these bars totally get it. Sweet, pink, chewy, and unapologetically extra.

Exactly my kind of dessert, always.

Strawberry cake mix brings that bright berry flavor and keeps things super easy.
Eggs help the bars set, so they’re gooey but not a total mess.
Vegetable oil makes the crumb soft, rich, and a little fudgy.
Vanilla extract adds cozy sweetness that makes the strawberry taste less boxed.
Sweetened condensed milk is the sticky magic that makes these bars gooey.
White chocolate chips melt into creamy pockets, and yes, they’re very sweet.
Fresh strawberries add juicy bites and make everything feel a bit fresher.
Plus, pan spray or butter saves you from scraping dessert off the dish.
Basically, powdered sugar makes them look bakery-cute with almost no effort.

Ingredient Quantities

1 (15.25 ounce) box strawberry cake mix

2 large eggs

1/2 cup vegetable oil

1 teaspoon vanilla extract

1 (14 ounce) can sweetened condensed milk

1 1/2 cups white chocolate chips

1 cup fresh strawberries, hulled and chopped

Nonstick cooking spray or butter for the pan (optional)

Powdered sugar for dusting (optional)

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 350 degrees F and lightly grease a 9×13 inch baking pan with nonstick spray or butter.

2. In a large bowl whisk together the strawberry cake mix, eggs, vegetable oil, and vanilla until a thick, uniform batter forms.

3. Reserve about half of the batter in the bowl and press the remaining half evenly into the bottom of the prepared pan to form a base layer.

4. Pour the sweetened condensed milk evenly over the base layer.

5. Sprinkle 1 cup of the white chocolate chips and the chopped fresh strawberries evenly over the condensed milk.

6. Crumble or dollop the reserved batter over the top to partially cover the filling; it is fine if some filling shows through.

7. Scatter the remaining 1/2 cup white chocolate chips over the top.

8. Bake until the top is set and golden at the edges and a toothpick inserted into the cake layer comes out with a few moist crumbs, about 25 to 30 minutes.

9. Cool completely in the pan on a wire rack so bars firm up, then cut into squares.

10. If desired, dust with powdered sugar before serving.

FAQ

What pan size and oven temperature should I use? Preheat oven to 350°F. Use a 9×13 inch baking pan lined with parchment or greased; bake 22 to 28 minutes until edges are set and center is slightly soft.

Can I use frozen strawberries instead of fresh? Yes, but thaw and drain them well first to avoid excess moisture that can make the bars soggy.

How do I know when the bars are done? The edges should look set and golden while the center remains slightly soft and gooey. A toothpick inserted near the center may come out with a few moist crumbs but not wet batter.

How should I store and how long will they keep? Cool completely, then store in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 5 days. Rewarm gently in a low oven or microwave for a few seconds to restore gooeyness.

Can I substitute white chocolate chips or use a different chocolate? Yes. You can use milk or semi sweet chips, but white chocolate pairs best with the strawberry flavor. If using a different chip, expect a change in sweetness and texture.

Any tips for cutting clean squares? Chill the bars for 20 to 30 minutes after cooling, then use a sharp knife wiped clean between cuts. Dust with powdered sugar just before serving if desired.

Strawberry White Chocolate Gooey Bars Recipe Substitutions and Variations

Strawberry cake mix: swap for a vanilla or white cake mix (same weight) or make a quick homemade mix using 1 3/4 cups all-purpose flour, 1 cup granulated sugar, 1 tbsp baking powder and a pinch of salt; add 1/4 cup freeze-dried strawberry powder or 1/2 cup finely chopped fresh strawberries for flavor.
Eggs: use flax “eggs” (1 tbsp ground flaxseed mixed with 3 tbsp water per egg, let sit 5 minutes) or 1/4 cup applesauce per egg for a moist, egg-free option.
Vegetable oil: substitute equal parts melted unsalted butter for richer flavor, or use applesauce for a lower-fat swap (use 3/4 to 1 cup applesauce in place of 1/2 cup oil and expect a slightly denser texture).
White chocolate chips: swap for chopped white chocolate from a bar or use vanilla-flavored chips; if you want contrast, use semi-sweet chocolate chips instead.

Pro Tips

1. Use room temperature eggs and oil so the batter comes together smoothly and bakes more evenly. Cold ingredients can give you uneven texture and longer bake times.

2. Chop the strawberries into small, uniform pieces and pat them lightly with a paper towel to remove excess moisture. That prevents the bars from getting soggy while still keeping bright fruit pockets.

3. Gently press the base layer without compacting it too much. You want a solid foundation but a little lift helps the condensed milk and fruit mingle without turning the crust gummy.

4. For creamier pockets of white chocolate, warm the chips for 10 to 20 seconds in the microwave and stir before scattering a few spoonfuls into the filling. Be careful not to overheat or they will seize.

5. Cool completely in the pan before cutting, preferably chilling for 30 to 45 minutes if you can wait. The filling firms up as it cools, giving cleaner slices and a neater presentation.
