Soft and gooey chocolate brownie

I've been trying to find recipes of food, snacks and sweets that are good to freeze so that when the baby comes we can always just go to the freezer because we probably won't have the energy or time to cook every night and we don't want to get take-out all the time. So I'm trying to prepare as much as possible while I'm not working. I found this recipe on paleogrubs.com and it's a super easy recipe with not that many ingredients and it's pretty much like a normal chocolate cake/brownie.

Ingredients
makes about 10 brownies/1 round cake
240 ml almond butter
80 ml maple syrup
1 egg
2 tbsp melted ghee
1 tsp vanilla
80 ml cocoa powder
½ tsp baking soda

Preheat the oven to 170 degrees Celsius. In a large bowl, whisk together the almond butter, maple syrup, egg, ghee and vanilla. Stir in the cocoa powder and baking soda gently.
Pour the batter into a 22 cm baking pan (I used a round one).
Bake for 20-23 minutes, until the brownie is done, but still soft in the middle.
Let cool and enjoy by itself or with some berries and cream.
