FAQs
Why use butter instead of oil?
Butter adds a richer flavor and improves the texture, making the brownies taste more homemade.
Can I use milk instead of water?
Yes, milk makes the brownies more moist and creamy. Coffee adds depth and enhances chocolate flavor.
How do I make the brownies extra fudgy?
Use one less egg and bake until just set in the center. Avoid overbaking.
Can I make these in a different pan size?
Yes, adjust the baking time accordingly—smaller pans yield thicker brownies and may take longer.
What mix-ins work best?
Chocolate chips, peanut butter chips, nuts, crushed cookies, or swirls of jam or Nutella.
How do I keep brownies moist?
Don’t overbake them, and store tightly covered once cooled.
Can I add frosting?
Yes! Chocolate ganache, cream cheese frosting, or a dusting of powdered sugar all work well.
How can I tell when they’re done?
Insert a toothpick near the edge—it should come out with moist crumbs but not wet batter.
Do I need to use the same brand of mix?
No, this method works with any standard boxed brownie mix.
Can I make brownie bites or muffins?
Yes, use a greased or lined mini muffin tin and reduce bake time to about 12–15 minutes.
