3/4cupheavy creamor unsweetened almond milk or coconut cream - at room temperature
Preheat oven to 350°F (180°C). Grease a round 9-inch pie dish with butter or coconut oil. Don't use a bigger dish or you won't be able to cover it with the quantity of blueberries suggested in this recipe. You can use a smaller baking dish but the biscuit batter will be thicker and it will take longer to bake. Set aside.
In a large mixing bowl, combine the fresh peach slices with erythritol and psyllium husk. Note that you can make this recipe without psyllium husk or xanthan gum but the filling will be more watery and it will soften the bottom of the cobbler biscuit.
Arrange the peach slices into a single layer in the baking dish. Set aside on the counter while you are making the cobbler biscuit.
In another mixing bowl, whisk together the almond flour, coconut flour, erythritol, salt and baking powder.
Stir in beaten egg, melted butter (or coconut oil), and heavy cream until it forms a thick creamy biscuit batter. If your batter is very dry, this may happen if you used almond meal or too much coconut flour, add more cream - 1 tablespoon at a time.
Spoon the batter roughly onto the peaches.
Bake for 35-45 minutes in the center rack of your oven. I recommend you cover the baking dish with a piece of foil if the top browns too fast. It is ready when the top of the biscuit is very crispy and peaches form a jam-like texture and bubbles shows on the side of the baking dish.
Cool 2-3 minutes then serve in individual bowls, 1/3 cup per person, with a dollop of unsweetened whipped cream on top, some coconut cream, or yogurt. These toppings won't add carbs so be generous!
Store the cobbler for 3 days in the fridge in an airtight container.
Rewarm in hot oven, 350°F (180°C) for 10 minutes on top rack, in oven-proof ramekin, until lukewarm and crispy on top. You can switch the oven to broil mode for 1 minute to boost the crispiness.
Can I use canned peaches? Yes, if they are not stored in their juice like this one, but in water and it says no added sugar on the box. Read the ingredient list it should have juice or sugar, only peaches, water, and optionally citric acid, Vitamin C.
