Keto Raspberry Almond Crumble Cake (With That Perfect Jammy Layer)
Let me paint you a picture: golden-brown crumb topping crunching under your fork, giving way to a soft, moist almond-scented cake base… then BAM — juicy, tart raspberries oozing through the middle like nature’s candy. Topped with toasted sliced almonds and a dusting of powdered sweetener? Yeah, this is dessert royalty.
It’s rustic enough for Sunday brunch but fancy enough for “I’m treating myself because I deserve it” Tuesday nights. The texture combo? Unbeatable. Crunch + squish + melt = pure joy. And yes, it’s 100% keto-friendly. No guilt, all glory.
Ingredients:
For the Cake Base:
1 ½ cups super-fine almond flour
¼ cup coconut flour
1 tsp baking powder
¼ tsp salt
½ cup unsalted butter, softened
¾ cup granulated erythritol or monk fruit sweetener
2 large eggs
1 tsp vanilla extract
1 tbsp lemon juice (brightens the berries!)
For the Raspberry Layer:
1 ½ cups fresh or frozen raspberries (don’t thaw if frozen!)
1 tbsp chia seeds or xanthan gum (optional, helps thicken juices)
For the Crumble Topping:
½ cup almond flour
¼ cup chopped pecans or walnuts (optional, adds crunch)
3 tbsp cold unsalted butter, cubed
2 tbsp granulated sweetener
½ tsp cinnamon
Pinch of salt
For Garnish:
¼ cup sliced almonds, lightly toasted
Powdered erythritol or monk fruit, for dusting
Instructions:
Prep & Preheat: Preheat oven to 350°F (175°C). Grease a 9-inch round springform pan or line with parchment paper. Place on a foil-lined baking sheet (catches any bubbly overflow!).
Make the Batter: In a medium bowl, whisk almond flour, coconut flour, baking powder, and salt. In another bowl, cream butter and sweetener until fluffy. Add eggs one at a time, then vanilla and lemon juice. Fold in dry ingredients until just combined. Spread evenly into prepared pan.
Add Berries: Scatter raspberries over batter. If using chia/xanthan, sprinkle lightly over berries to help absorb juice. Don’t press them in — let them sit pretty on top.
Make Crumble: In a small bowl, mix almond flour, nuts (if using), sweetener, cinnamon, and salt. Cut in cold butter with fingers or pastry cutter until mixture resembles coarse crumbs. Sprinkle evenly over berries.
Bake: Bake 45–55 minutes until topping is golden brown and center is set (a toothpick should come out clean from cake layer, not berry zone). Let cool 15 mins before removing ring.
Garnish & Serve: Toast sliced almonds in a dry skillet 2–3 mins until fragrant. Dust cake with powdered sweetener. Slice warm or chilled — both are magical.
Pro Tips to Make It Shine:
Frozen Berries Work! Just don’t thaw — they’ll release less water during baking. Add 5 extra mins bake time if needed.
Toasted Nuts = Flavor Boost: Toast sliced almonds AND any chopped nuts in the crumble for deeper, nuttier flavor.
No Springform Pan? Use a regular 9-inch round pan lined with parchment sling — lift out after cooling.
Make Ahead? Bake 1 day ahead. Store covered at room temp 1 day, or fridge up to 3 days. Reheat slices gently in microwave or toaster oven.
Extra Fancy? Drizzle with sugar-free white chocolate or serve with whipped cream made from heavy cream + powdered sweetener.
