Dry ingredients
2 cups old-fashioned rolled oats
1 tablespoon chia seeds
1 teaspoon ground cinnamon
1 teaspoon baking powder
1/2 teaspoon salt
1/2 cup dairy-free dark chocolate chips
Wet ingredients
1/2 cup natural peanut butter, unsalted
1 1/2 cups unsweetened almond milk
1 flax egg (1 tablespoon flax meal mixed with 3 tablespoons lukewarm water)
1/4 cup pure maple syrup
1 teaspoon vanilla extract
Directions
Preheat the oven to 350°F (180°C). Lightly grease a 9-inch square baking dish and set aside.
Prepare the flax egg by mixing the flax meal with lukewarm water in a small bowl. Let it rest for 5 minutes until thick and gel-like.
In a large mixing bowl, combine the oats, chia seeds, cinnamon, baking powder, salt, and chocolate chips. Stir until evenly mixed.
In a separate bowl, whisk together the peanut butter, almond milk, maple syrup, vanilla extract, and prepared flax egg until smooth and fully combined.
Pour the wet mixture into the bowl with the dry ingredients and stir until everything is evenly moistened.
Transfer the mixture into the prepared baking dish and spread it out evenly.
Bake on the center rack of the oven for 35 to 45 minutes, until the top is lightly golden and the center is set.
Remove from the oven and let cool for about 15 minutes before slicing and serving.
