How to Make Keto Strawberry Rhubarb Dump Cake – Step by Step

Follow these simple steps to create the perfect Keto Strawberry Rhubarb Dump Cake that will satisfy your dessert cravings without the carbs.

Step 1: Prepare for Baking

Preheat your oven to 350°F (175°C). Lightly grease an 8×8 inch baking dish or a 9-inch pie plate with butter or cooking spray.

Step 2: Create the Fruit Filling

In a medium bowl, combine the chopped rhubarb and strawberries. Sprinkle the powdered sweetener and glucomannan (or xanthan gum) over the fruit. Toss gently until all pieces are coated. The thickening agent will help create that perfect jammy consistency as it bakes.

Step 3: Transfer Filling to Baking Dish

Pour the fruit mixture into your prepared baking dish, spreading it evenly across the bottom.

Step 4: Make the Cake Topping

In a separate bowl, whisk together the almond flour, coconut flour, granulated erythritol, baking powder, and salt until well combined.

Step 5: Add Melted Butter

Pour the melted butter into the dry mixture and stir until you achieve a crumbly dough. It should resemble wet sand that clumps together when pressed.

Step 6: Add Topping to Fruit Layer

Sprinkle the topping mixture evenly over the fruit filling, covering it completely. Don’t press it down – the beauty of a dump cake is its rustic appearance.

Step 7: Bake to Perfection

Bake in your preheated oven for 40-45 minutes, until the topping is golden brown and the fruit filling is bubbling around the edges.

Step 8: Cool Slightly

Allow your Keto Strawberry Rhubarb Dump Cake to cool for at least 15 minutes before serving. This helps the filling set to the perfect consistency.

Pro Tips for Making the Best Keto Strawberry Rhubarb Dump Cake

Want to elevate your Keto Strawberry Rhubarb Dump Cake to the next level? These professional tips will help you nail this recipe every time:

• Balance the flavors: If your rhubarb is particularly tart, you may want to add an extra tablespoon of sweetener to the filling.
• Texture matters: For a more traditional “cake-like” topping, whisk an egg into the melted butter before combining with the dry ingredients.
• Avoid sogginess: If your strawberries are very juicy, toss them with the thickening agent first, then add the rhubarb and sweetener.
• Perfect golden crust: For an extra golden topping, sprinkle a tablespoon of granulated erythritol on top during the last 10 minutes of baking.
• Prevent dry topping: Check the cake after 30 minutes – if the topping looks dry, brush lightly with a tablespoon of melted butter.
