Mix flaxseed meal and water. Let it thicken into your classy vegan egg—about 5 minutes.
In one bowl, whisk flour, baking soda, and salt.
In another, beat vegan butter, brown sugar, and granulated sugar until it’s smooth and flirty.
Stir in flax egg and vanilla. Whip it good.
Add dry ingredients slowly, forming a dreamy dough.
Fold in dark chocolate chips. Taste a few—you earned it.
Chill the dough for 10 minutes (your patience can handle it).
In a separate bowl, mix vegan cream cheese, hazelnut butter, espresso, powdered sugar, and a pinch of salt.
Scoop 1 tbsp of dough, flatten it, add ½ tsp of filling, then top with another scoop of dough.
Seal and shape into thick cookie domes.
Bake at 350°F (175°C) for 12 minutes until golden and slightly puffy.
Cool for 10 minutes. Resist biting too early unless you like lava-mouth.
