Mastering Gooey Raspberry Coffee Cake Bars: How-To

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This is crucial for baking your Gooey Raspberry Coffee Cake Bars to perfection.
Step 2: Prepare Your Baking Dish
Grease your 9×13 inch baking dish with a little butter or cooking spray to prevent sticking.
Step 3: Mix the Batter
In a large mixing bowl, combine the cake mix, egg, and melted butter. Stir until well combined. The batter will be thick and slightly crumbly.
Step 4: Spread the Batter
Using a spatula, spread half of the batter into the prepared baking dish. Make sure to create an even layer.
Step 5: Add the Filling
Spread the raspberries evenly over the layer of batter. Drizzle the condensed milk over the raspberries, followed by a generous sprinkle of white chocolate chips.
Step 6: Prepare the Topping
In a small bowl, combine the brown sugar, all-purpose flour, cold butter pieces, and cinnamon. Use a fork or your fingers to mix until crumbly. Sprinkle this mixture evenly over the filling.
Step 7: Bake
Bake the bars in the preheated oven for 25-30 minutes, or until the top is golden and a toothpick inserted in the center comes out clean.
Step 8: Cool and Serve
Allow the bars to cool in the baking dish for at least 15 minutes before cutting into squares. Serve warm or at room temperature.

Mistakes That Ruin Gooey Raspberry Coffee Cake Bars
To ensure your Gooey Raspberry Coffee Cake Bars turn out perfectly, avoid these common mistakes:
- Not greasing the baking dish properly, leading to sticking.
- Overmixing the batter, which can result in dense bars.
- Skipping the cooling time, as this helps the bars set properly.
- Using too much filling can cause the bars to be overly soggy.
Storing Tips & Timelines
To keep your Gooey Raspberry Coffee Cake Bars fresh:

Gooey Raspberry Coffee Cake Bars Q&A
Can I use frozen raspberries instead of fresh?
Absolutely! If using frozen raspberries, just ensure they are thawed and drained before adding them to the bars. This will prevent excess moisture.
What can I substitute for white chocolate chips?
You can substitute white chocolate chips with dark chocolate chips, butterscotch chips, or even chopped nuts for a different texture and flavor.
How do I know when the bars are done baking?
The bars are done when the top is golden brown and a toothpick inserted into the center comes out clean. If it comes out with wet batter, they need more time.
Can I make these bars in advance?
Yes! These bars can be made ahead of time and stored in the refrigerator. They taste even better after a day or two as the flavors meld together.
