Even my sugar-loving sister asked for seconds—and didn’t realize it was keto.
I’ve Tested So Many Sad Cobblers. This One Finally Delivers.
You know that moment when you’ve got a killer summer haul of blackberries… and then every low-carb “cobbler” recipe turns into either a dry protein bar on top or a watery jam soup?
Yeah, I’ve lived it.
This version finally nailed the balance: a gooey, slightly tart berry base (thanks, lemon + gelatin) and a golden almond flour topping that’s actually crumbly—not gritty, not eggy, and not trying to be cake. It’s low-carb comfort in a bowl.
I’ve made it dairy-free, too, for my bloat-averse days. And it reheats like a dream.
Why This One Works So Well
- Gelatin for the win: It thickens the filling without starch or xanthan. Just sprinkle slowly or it’ll clump—been there, fixed that.
- Almond flour topping: No eggs, no cheese, no weird binding. Just fat + flour = real crumble vibes.
- Sweetened just enough: Monk fruit allulose blend plays nice here—no cooling aftertaste, and it browns like sugar.
What I Used (And Why It Worked)
For the Filling:
- Blackberries (450g / 1 lb) – Low in net carbs, big on flavor. Fresh works best. Frozen = fine if you drain well.
- Lemon juice (2 tbsp) – Brightens the berries and offsets the monk fruit sweetness.
- Monk Fruit Allulose Blend (67g / ⅓ cup) – Tastes like sugar and browns like it too. Less cooling effect than erythritol.
- Unflavored gelatin (2 tbsp) – Keeps it from becoming a puddle. Essential. Don’t skip.
For the Crumble Topping:
- Blanched almond flour (100g / 1 cup) – Blanched is smoother. Don’t sub coconut flour unless you want a dry disaster.
- More Monk Fruit Allulose Blend (50g / ¼ cup) – Or less if your berries are sweet enough.
- Baking powder (½ tsp) – Adds a little lift to the topping.
- Sea salt (¼ tsp) – Balances the sweetness.
- Coconut oil (¼ cup) – Or sub butter/ghee for non-dairy-free days. Fat = flavor.
- Vanilla extract (½ tsp) – Optional, but adds a warm depth to the topping.
Keto Swaps That Actually Work
Swap | Works? | Notes |
---|---|---|
Butter for coconut oil | ✅ | Slightly richer flavor, not dairy-free |
Frozen berries | ✅ | Thaw + drain well or the filling gets soupy |
Coconut flour for almond | ❌ | Just don’t—completely changes texture |
Gelatin for chia | ⚠️ | Technically works, but more jammy and less set |
What I Got Wrong
What Went Wrong | Why It Happens | How to Fix It |
---|---|---|
Watery filling | Didn’t drain frozen berries or rushed the gelatin | Thaw and drain berries fully. Sprinkle gelatin in two rounds |
Topping too soft | Used superfine almond flour | Use regular blanched for better crumble texture |
Over-sweet | Berries were already sweet | Taste before baking and dial down sweetener if needed |
Step-By-Step Cobbler Magic
- Preheat oven to 180°C / 350°F.
- Toss blackberries with lemon juice and sweetener.
- Sprinkle gelatin over berries—one tablespoon at a time, mixing in between.
- Pour into 8×8″ dish (glass or non-stick).
- Melt coconut oil, stir in vanilla.
- Mix dry topping ingredients, then stir into the oil until crumbly.
- Crumble topping over berries—leave a few gaps for bubbling goodness.
- Bake 25–30 minutes until golden and juicy.
- Cool 10+ minutes before serving. Trust me—it sets better and scoops clean.

Keto Cooking Tricks That Help
- I portion this into 9 servings so I can track my macros without mental math.
- Letting the topping cool before covering avoids sogginess.
- I mix extra dry topping and freeze it for a fast cobbler another day.
How I Store and Track It
- Fridge: 4 days, sealed.
- Freezer: Up to 3 months. Freeze in individual slices to avoid the soggy middle issue.
- Reheat: I pop it in the toaster oven. But honestly? It’s also amazing cold with a dollop of whipped cream.
Can I Eat This on Keto? (Yes, Here’s Why)
