Ingredients You’ll Need

To whip up this delicious dump cake, gather the following ingredients:

  • 1/2 cup butter (1 stick, or you could use margarine)
  • 1 cup flour (all purpose or whole wheat pastry flour)
  • 1 cup sugar
  • 1 cup milk (skim, almond milk, or other dairy-free options work well)
  • 1 pint blueberries

Ingredient Notes, Variations & Simple Swaps

Equipment Needed

  • Oven
  • Skillet (preferably cast iron or oven-safe)
  • Mixing bowl
  • Whisk or spoon

How to Make This Recipe

Step 1 – Preheat the Oven

Start by preheating your oven to 375°F. While it’s warming up, prepare your skillet by greasing it with cooking spray or butter to prevent sticking.

Step 2 – Make the Batter

In a separate bowl, melt the butter in the microwave for about 30 seconds until it’s completely liquid. Once melted, add in the flour, sugar, and milk. Whisk everything together until you have a smooth batter with no large clumps.

Step 3 – Add the Blueberries and Bake

Pour the batter into the prepared skillet, spreading it evenly. Sprinkle the blueberries on top, making sure they’re distributed fairly. Place the skillet in the oven and bake for 40-45 minutes. You’ll know it’s done when the edges start turning slightly brown. Remove it from the oven and let it cool for about 10 minutes before serving warm or cold.

Tips for Perfect Results

To ensure your dump cake comes out perfectly every time, consider these tips:

  • Make sure your butter is fully melted; lumpy batter will affect the final texture.
  • Whisk the batter well to avoid any dry pockets of flour.
  • If using frozen blueberries, there’s no need to thaw them; just toss them in as is.
  • Keep an eye on the cake during the last few minutes of baking to prevent over-browning.
  • Allow the cake to cool slightly before serving for easier slicing.

Flavor Variations

While this blueberry dump cake is fantastic on its own, here are a few tasty variations you can try:

  • Swap blueberries for strawberries or cherries for a fruity twist.
  • Add a teaspoon of vanilla extract to the batter for extra flavor.
  • Mix in a teaspoon of cinnamon or nutmeg for a warm spice note.
  • Top with a dollop of whipped cream or vanilla ice cream for a special touch.

What to Serve With This Recipe

This delicious dump cake pairs wonderfully with a variety of items. Here are some ideas for serving:

  • A scoop of vanilla ice cream or whipped cream
  • Fresh fruit for a refreshing contrast
  • A drizzle of honey or maple syrup for added sweetness
  • Coffee or tea for a delightful afternoon snack

Storage, Make-Ahead & Leftovers

For storing your dump cake, cover it with plastic wrap or transfer it to an airtight container to keep it fresh. It can be kept in the fridge for up to three days. If you’d like to make it ahead of time, prepare the batter and pour it into the skillet, then cover it until you’re ready to bake. If you have leftovers, you can enjoy them cold or reheat individual portions in the microwave for a quick treat.
