Combine brownie mix, oil, eggs, and water in a large bowl; whisk together until smooth.

Pour 1/2 cup of the brownie batter into a squeeze bottle, pastry bag with a small round tip, or large resealable plastic bag with corner snipped off. Reserve remaining batter.

6 . Stage

Heat a large nonstick skillet over medium-low heat. Drop 1/3 cup pancake batter into the skillet, shaking skillet to spread batter evenly.

Repeat with remaining batters.
