Notes

Optional Add-Ins

The basic recipe for this homemade brownie mix is perfect, but it’s always fun to customize and add a personal touch to your baked goods. You can enhance the flavors and textures of your brownies with a variety of optional add-ins. Just remember to only add shelf-stable items to the dry mix in the jars!
Add-In Benefit
Chocolate Chip For an extra dose of chocolaty goodness, fold in a handful of chocolate chips. They melt into gooey pockets of delight, making every bite more indulgent.
Candies Try different candies such as M&M’s, crushed peppermint candy, toffee bits, or caramels to add an interesting twist.
Various Extracts Play around with different extracts such as vanilla, peppermint, hazelnut, or orange, to enhance sweetness and aroma.
Chopped Nuts Walnuts, pecans, or almonds add a delightful crunch and nutty flavor that pairs perfectly with the rich cocoa base of the brownies.
Marshmallows Mix in mini marshmallows for a fun, chewy texture that kids and adults alike will love. They create a gooey topping that caramelizes beautifully while baking. (If you add some crushed-up graham crackers, you’ve just made a S’mores version!)

Tips for the Best Homemade Brownie Mix

Perfect brownies are easy to achieve when you know a few simple baking tricks. Here are my top tips to transform this homemade brownie mix into the best brownies you’ve ever baked:
  • Fat Sources – Choosing between melted butter and vegetable oil affects the texture. Melted butter gives a rich taste, while vegetable oil makes them moist and chewy. You can try mixing both to get the best of both worlds.
  • Quality Ingredients – Using high-quality cocoa powder is key for a deep chocolate flavor. Dutch-processed cocoa offers a smoother taste. Adding dark or milk chocolate chunks can make them even more indulgent.
  • Mixing Techniques – Sifting your dry ingredients like flour, sugar, and cocoa powder is important. It prevents lumps and ensures even mixing. This simple step greatly improves your brownies’ texture. Additionally, don’t overmix the batter because overmixing can make your brownies tough. Just mix until the ingredients are combined.
  • Choosing Texture – Fat is the secret to fudgy brownies. For extra moist brownies, add an extra tablespoon of coconut oil. If you prefer a cake-like consistency, add an extra egg.
  • Choosing Consistency – For gooey brownies, don’t overbake! Remove from the oven as soon as the toothpick comes out clean. For firmer brownies with crispy edges, add a few minutes of baking time and allow to cool completely before slicing.
  • Enhancing the Flavor – Coffee complements the chocolate and really brings out its flavor. To deepen the chocolate flavor without an overwhelming coffee taste, add a teaspoon of espresso powder, you won’t even notice it’s there.
