Gooey Raspberry Coffee Cake Bars — Do This Next

Now, let’s get into the step-by-step process of creating these heavenly bars.
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Grease your 9×9-inch baking dish or line it with parchment paper for easy removal.
Step 2: Make the Cake Base
In a large mixing bowl, combine the cake mix, melted butter, and egg. Stir until the mixture is well combined and resembles a thick batter.
Step 3: Assemble the Base in the Baking Dish
Spread the cake batter evenly into the prepared baking dish, pressing it down gently to create a smooth layer.
Step 4: Add the Raspberries
Evenly distribute the raspberries over the cake batter, gently pressing them in to ensure they stick.
Step 5: Prepare the Gooey Filling
In a separate bowl, combine the condensed milk, white chocolate chips, brown sugar, all-purpose flour, and cinnamon. Mix until smooth. Pour this mixture over the raspberries, spreading it evenly.
Step 6: Make the Topping
In another bowl, take the cold butter pieces and combine them with the remaining cake mix (approximately 1/2 cup), brown sugar, and cinnamon. Use your fingers or a pastry cutter to create a crumbly topping. Sprinkle this mixture evenly over the top of the gooey filling.
Step 7: Bake
Place the baking dish in the preheated oven and bake for about 30-35 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
Step 8: Cool and Slice
Once baked, remove the dish from the oven and allow the bars to cool in the pan for at least 15 minutes. Then, transfer them to a wire rack to cool completely before slicing into squares.
Tailor It to Your Diet

If you have specific dietary preferences, here are some easy ways to customize the recipe:
- Dairy-Free: Substitute the butter with a dairy-free alternative and use dairy-free white chocolate chips.
- Gluten-Free: Swap the cake mix for a gluten-free variety and use gluten-free all-purpose flour.
- Low-Sugar: Use a sugar-free cake mix and reduce the amount of brown sugar in the topping.
- Fruit Variations: Replace raspberries with blueberries, strawberries, or a mix of your favorite berries.
Don’t Do This
To ensure your Gooey Raspberry Coffee Cake Bars turn out perfectly, avoid the following common mistakes:
- Don’t skip greasing the baking dish; it helps prevent sticking.
- Avoid overmixing the batter, which can lead to tough bars.
- Don’t use overly ripe or mushy raspberries, as they can turn the filling too watery.
- Be careful not to underbake; the bars should be set in the center for the perfect texture.
Keep-It-Fresh Plan
To keep your Gooey Raspberry Coffee Cake Bars fresh and delicious, follow these tips:
- Store in an airtight container at room temperature for up to 3 days.
- For longer storage, freeze the bars. Wrap them individually in plastic wrap and place them in a freezer-safe bag. They can last up to 3 months.
- When ready to enjoy, thaw at room temperature or warm in the microwave for a few seconds.
- Consider adding a sprinkle of powdered sugar on top before serving for an extra touch of sweetness.
Your Questions, Answered
Can I use frozen raspberries instead of fresh?
Absolutely! Frozen raspberries work wonderfully in this recipe. Just be sure to thaw and drain them to avoid excess moisture.

Can I mix in other flavors?
Definitely! Feel free to add nuts, coconut, or even a splash of vanilla extract to the batter for added flavor.
What should I serve with these bars?
