Equipment

Mixing bowl
8" x 8" baking dish

Ingredients

¼ cup ground flax
½ cup water
½ cup vegan butter, melted
1½ cups white sugar
⅔ cup unsweetened cocoa powder optionally sifted
2 teaspoon vanilla extract
¾ cup all purpose flour
1 teaspoon baking powder
¾ cup non-dairy chocolate chips
9 Oreos
⅓ cup peanut butter slightly melted if needed

Instructions

Mix together the ¼ cup ground flax and the ½ cup water to make flax eggs. Set aside for about 5 minutes to thicken.
Preheat the oven to 350℉. Prepare an 8" x 8" baking dish by cutting 2 pieces of parchment paper and laying them in the dish like a "t". This makes it super easy to take the brownies out of the pan to cut.
In a medium mixing bowl, whisk together the ½ cup vegan butter, melted, 1½ cups white sugar, ⅔ cup unsweetened cocoa powder, and the 2 teaspoon vanilla extract. Make sure there aren't any lumps. Stir in the flax eggs.
Stir in the ¾ cup all purpose flour and the 1 teaspoon baking powder until just combined. Fold in the ¾ cup non-dairy chocolate chips.
Pour the brownie batter into the prepared baking dish. Drop the ⅓ cup peanut butter in spoonfuls on top of the batter. Use a toothpick to swirl the peanut butter. If your peanut butter is more solid (depending on the kind you use), microwave it first for about 15 seconds to make it more liquid.
Place the 9 Oreos in a 3 x 3 pattern on top of the batter.
Bake in the oven for about 35-40 minutes. Take the pan out of the oven and let cool for about 30 minutes in the pan before transferring to a wire rack to cool completely. Use the parchment paper to easily lift out the brownies and place on the rack.
Store any leftovers in an airtight container at room temperature for up to 4 days.

Notes

Do not overmix the batter.
If you are using a natural peanut butter that's kept in the fridge, you'll probably need to slightly melt it first so you'll be able to swirl it.
If the peanut butter starts to brown, lightly cover with aluminum foil.
The amount of baking time can depend on the type of pan. Brownies made in glass pans take a few minutes more to cook than if they were baked in metal pans.
