These fudgy brownie bites are the easiest way to get rich, chocolatey brownies on the table fast. Made with a box brownie mix and baked in a mini muffin pan, they give you all the flavor of classic brownies in a grab-and-go size that's perfect for lunchboxes and after-school snacks.
One of my favorite things about this recipe is how quickly it comes together. From mixing to baking, you can have 2-bite brownies ready in under 30 minutes, with no slicing and no waiting for a big pan to cool.

Ingredient Notes
- Brownie mix: Use a standard 18-19 oz box. Any brand that has a fudgy brownie will work but I don't recommend using one with mix-ins like chocolate chips or nuts.
- Vanilla: Real or imitation will work. Use what's in your pantry.
- Espresso powder + water: The espresso deepens the chocolate flavor. You can substitute 2 TB of brewed coffee if you don't have espresso powder.
💡My Tips for Perfect Brownie Bites
- Use mini muffin liners if you want easy cleanup. Liners make the brownie bites easy to remove from the pan and perfect for packing into lunchboxes & taking on the go.
- Don't overbake. Pull the brownie bites out of the oven as soon as the centers look set. Overbaking leads to dry brownies and no one wants that!
- Stick to a cookie scoop. Filling the muffin tin evenly with a cookie scoop (or even a Tablespoon measuring spoon) helps all the brownie bites bake at the same rate, so you don't end up with some overdone and others underbaked.
How to Make Brownie Bites
Step 1: Preheat the oven according to the brownie mix package directions. Fill the mini-muffin pan with paper liners. Then, in a small bowl or measuring cup, stir the espresso powder into the water until dissolved.
Step 2: In a medium mixing bowl, combine the brownie mix, eggs, oil, vanilla, and the espresso mixture.
Step 3: Stir just until fully mixed.
Step 4: Using a small cookie scoop, fill each mini muffin cup about ¾ full.
Step 5: Bake for 12-15 minutes, until the tops are set and the centers no longer look wet. Do not overbake. Let the brownie bites cool in the pan for a few minutes, then remove and transfer to a cooling rack to cool completely.
Recipe FAQ's
Yes and no. Because brownie bites bake faster and in smaller portions, the centers stay softer while the edges set quickly. You get that fudgy brownie texture without the dry corners that can happen in a large pan.
You can, but the chocolate flavor won't be as deep. The espresso powder doesn't make them taste like coffee, it just enhances the chocolate. You can substitute it with the same amount of brewed coffee.
Brownie bites dry out when they bake too long. Check them early and pull them as soon as the centers look set. They'll continue to firm up as they cool.
Yes. These are great for baking ahead. Store them in an airtight container at room temperature for up to 5 days, or freeze for longer storage. Pop them into lunch boxes straight from the freezer, they will defrost by lunchtime. If you like baking once and freezing extras, my brownie mix cookies freeze just as well.
