Ingredients You’ll Need

For the Fruit Layer:

  • 2 cups fresh or frozen low-carb fruit (berries, sliced peaches, diced apples, or rhubarb)
  • 1–2 tbsp lemon juice (to preserve color and enhance flavor)
  • 1/4 cup powdered erythritol or monk fruit sweetener
  • 1 tsp vanilla extract
  • Pinch of salt

Optional: 1/2 tsp cinnamon or nutmeg for spiced flavor


For the Crumb Topping:

  • 1 cup almond flour
  • 1/4 cup coconut flour
  • 1/4 cup powdered erythritol or monk fruit sweetener
  • 1 tsp cinnamon (optional)
  • 1/4 tsp salt
  • 1/3 cup melted butter or coconut oil

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C) . Grease a 9×9-inch baking dish or 8×8-inch pan for easy removal.

Tip: Use a cast iron skillet for even baking and rustic presentation.


Step 2: Prepare the Fruit Base

In a mixing bowl, toss your chosen fruit with:

  • Powdered sweetener
  • Lemon juice
  • Vanilla extract
  • Salt
  • Optional: Cinnamon or nutmeg

Spread evenly in the bottom of your prepared pan.

Pro Tip: Berries work best fresh or partially frozen—apples and peaches should be peeled and sliced thinly.


Step 3: Mix the Topping

In a separate bowl, combine:

  • Almond flour
  • Coconut flour
  • Powdered sweetener
  • Cinnamon (if using)
  • Salt

Add melted butter or oil and stir until coarse crumbs form.

Note: The mixture should be thick and crumbly—not runny.


Step 4: Layer the Topping Over the Fruit

Sprinkle the topping evenly over the fruit layer—no need to mix!

Press lightly to help the topping settle and create a dense crust during baking.


Step 5: Bake Until Golden and Bubbly

Bake at 350°F (175°C) for 30–35 minutes , or until the top is golden brown and the fruit juices are bubbling up around the edges.

Let cool slightly before serving to allow the layers to set.


Step 6: Serve and Enjoy!

Scoop warm or chilled into bowls and enjoy every soft, fruity bite of your Keto Dump Cake .

Pair with whipped cream, Greek yogurt, or a scoop of keto ice cream for extra indulgence.

Keto Dump Cake – Rich, Fruity & Perfectly Low-Carp!


  • Author: WAFA LI
  • Total Time: 1 hr

Description

A delightful mix of sweet strawberries and tart rhubarb awaits!


Ingredients

🍓 2 1/2 cups (305 g) chopped rhubarb
🍓 1 cup (144 g) chopped strawberries
🍓 1/2 cup (91 g) powdered sweetener
🍓 1/2 tsp glucomannan (or xanthan gum)
🍰 1 1/4 cup (140 g) almond flour
🍰 1/3 cup erythritol sweetener
🍰 1/4 cup (30 g) coconut flour
🍰 2 tsp baking powder
🍰 1/4 tsp salt
🍰 2/3 cup (151.33 g) butter, melted


Instructions

Filling
Preheat the oven to 350ºF and grease a 2-quart glass or ceramic baking dish.
Add the rhubarb and strawberries to the dish and sprinkle with the sweetener and glucomannan. Toss well to combine.
Topping
In a medium bowl, whisk together the almond flour, sweetener, coconut flour, baking powder, and salt. Sprinkle evenly over the filling in the dish.
Drizzle the melted butter as evenly as possible over the topping. This works best by spooning it over, rather than pouring from a bowl.
Bake about 45 minutes, until the top is golden brown all over and the filling is bubbling up through in places. Remove and let cool (the topping will crisp up some as it cools).
