Preheat oven to 350°F (175°C). Line your pan with parchment like the baking queen you are.
In a bowl, whisk flour, cocoa, baking powder, and salt. Try not to inhale the cocoa like an amateur.
In another bowl, mix melted coconut oil and brown sugar until smooth—like your best excuse for skipping leg day.
Stir in milk, instant coffee, and vanilla. Combine it with the dry mix. The batter should look like edible sin.
Spread into your lined pan and smooth the top. Bake for 20 minutes until set but still fudgy. Cool completely.
Meanwhile, whip the vegan butter until fluffy. Add sugar slowly while pretending you’re on a baking show.
Mix in espresso, vanilla, and salt. Beat until light and spreadable. Try not to eat it straight from the bowl.
Once the base cools, slather that cream on like confidence at a bad date.
Chill for 20 minutes, slice into bars, and admire your work like it’s an art exhibit.
Serve with coffee, tea, or just cold sass.
