Classic Mixed Berry Dump Cake with Lemon and Ginger

A beautifully simple dessert that transforms fresh blueberries and raspberries into a bubbling, golden-topped treat with minimal effort. The berries are tossed with sugar, warming ginger, and bright lemon zest before being topped with cake mix and melted butter. As it bakes, the fruit juices meld with the cake to create a cobbler-like texture with crispy edges and tender pockets throughout. Perfect for summer gatherings, potlucks, or weeknight desserts when you want homemade taste without the fuss. The addition of fresh ginger and lemon this beyond typical dump cake recipes.

Tip 2

Tilt the pan in multiple directions when adding melted butter to ensure even coverage and prevent dry spots

Tip 3

Let cool the full 15 minutes to allow juices to thicken slightly and prevent a soupy texture when serving

FAQ

Can I use frozen berries instead of fresh?

Yes, but thaw and drain excess liquid first to prevent a watery cake. Frozen berries may break down more during baking.

What if I don't have a 13x9 pan?

Use a similar sized baking dish - the depth should be about 2 inches. Adjust baking time slightly if using a different shape.

How long will leftovers keep?

Store covered in refrigerator up to 3 days. The texture becomes softer but still delicious served cold or rewarmed.
