THM Blackberry Crisp | Keto, GF

Save for later!

Is it a THM blackberry crisp or crumble? You decide!

It’s been *gasp* literal years since I’ve created a new Trim Healthy Mama recipe, but the backyard of the house we are currently occupying is exploding with some might good Texas-sized blackberries, and I couldn’t let them go to waist!

I mean, waste.   

And since I’ve re-committed to Trim Healthy Mama in recent weeks, I thought I’d try putting the blackberries into a crisp – an S crisp, of course, so it can be served with whipped cream or some on-plan ice cream!

(Blackberries themselves are a fuel pull fruit, suitable for enjoyment in every fuel setting!) 

The trick to not burning a nutty, crumble topping is to allow the fruit a head start on cooking while you prepare it. 

Here’s how simple this recipe is:

First, you toss your berries in some sweetener, lemon juice, and xanthan gum. The xanthan gum thickens the juices into a nice, syrupy filling.

Pop the berry mixture into the oven while you prepare the topping.

Then you cut some butter into sweetener, cinnamon, coconut flakes, ground almonds, and salt for an incredibly delicious crumble topping.

Mmmm-mmmm! I could eat this stuff plain.

Remove the partially cooked berries from the oven to sprinkle on your topping. Return to oven and back until golden.

Try not to eat it all in one sitting, like my 3 year-old who had as many helpings of this THM Blackberry Crisp as her years.

    • Hi Lindy!

      Peaches are an E, so they would make this recipe a Crossover which is still on plan, but not necessarily conducive to weight loss. Hope that helps!!

  1. I had frozen blueberries that I needed to clear out of our freezer and they worked great. I just added the cook time of 5 minutes before putting on the topping. Yummy!
