Heat the oven to 375°F (190°C) and line a square 9x9 pan with parchment paper.
02 -
In a small pot, toss in the frozen berries (halve the larger ones if necessary), coconut sugar, maple syrup, lemon juice, and sea salt. Warm everything on low-medium heat for 5-10 minutes until the berries soften and release juices.
03 -
Scoop out a couple of tablespoons of berry liquid and mix it with tapioca starch in a small bowl. Stir till smooth, then pour it back into the pot. Mix over heat for another minute before taking it off the stove to set aside.
04 -
Stir oats, almond flour, sea salt, and baking soda in a big bowl. Add in the maple syrup, vanilla, and coconut oil. Use a fork first, then your hands, to make sure it all sticks together.
05 -
Save ½-¾ cup of the oat mix for the topping. Press the rest evenly into the lined baking pan.
06 -
Pour the berry mixture over the pressed crust and smooth it out so it’s even.
07 -
Take the reserved oat mix and crumble it on top of the berries. Press lightly if you want chunkier pieces.
08 -
Set it in the oven and bake for about 20-25 minutes, just until the edges are a bit golden.
09 -
Let everything cool all the way before cutting into squares so they stick together nicely. Store in the fridge for up to a week with a loose cover.
