Brownie Muffin Ingredients
Unlock the secret to these delicious brownie muffins with this simple ingredient list!
For the Muffin Batter
- Bittersweet or Semisweet Chocolate – Provides intense chocolate flavor and moistness; consider dark chocolate for a richer taste.
- Unsalted Butter – Adds richness, contributing to the fudgy texture; coconut oil can be a substitute, though the flavor will change.
- All-Purpose Flour – Gives structure to the muffins; gluten-free flour works as an alternative but may alter the result slightly.
- Unsweetened Cocoa Powder (Dutch-process) – Enhances the chocolate flavor; natural cocoa is a great alternative, though it may impact color and taste.
- Salt – Essential for balancing sweetness and enhancing flavors; don’t skip this ingredient!
- Large Eggs – Binds the ingredients together and helps the muffins rise; egg substitutes are not recommended for this recipe.
- Granulated Sugar – Sweetens the muffins and helps achieve that shiny top; feel free to swap with coconut sugar, but it will affect the flavor profile.
Step‑by‑Step Instructions for Ultimate Brownie Muffins
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (180°C). While the oven warms up, line a muffin tin with paper liners or grease them lightly. This step ensures that your ultimate brownie muffins release easily once baked and helps achieve that perfect, fudgy texture.
Step 2: Melt the Chocolate and Butter
In a medium microwave-safe bowl, combine the bittersweet or semisweet chocolate with unsalted butter. Microwave in 30-second intervals, stirring after each, until fully melted and smooth—about 1-2 minutes total. You can also melt them together over a double boiler on the stove if you prefer. Set aside to cool slightly.
Step 3: Mix Dry Ingredients
In a separate bowl, sift together 1 cup of all-purpose flour, ¼ cup unsweetened cocoa powder, and a pinch of salt. Ensure even mixing and eliminate any lumps, which will help create a smooth batter. Set this dry mixture aside while you prepare the wet ingredients for your brownie muffins.
Step 4: Whisk Eggs and Sugar
In a large mixing bowl, use an electric mixer to whisk 2 large eggs and 1 cup of granulated sugar on high speed. Continue whisking until the mixture becomes thick, pale, and forms ribbons—this should take about 4 minutes. The air incorporated here is crucial for a nice rise in your brownie muffins.
Step 5: Combine Wet and Dry Mixtures
Once your egg and sugar mixture has reached the desired consistency, reduce the mixer speed to low. Slowly drizzle in the melted chocolate and butter mixture, mixing until just combined. Be careful not to overmix, as this can affect the fudginess of your brownies—aim for a smooth consistency with a few streaks remaining.
Step 6: Fold in the Dry Ingredients
Stop the mixer and add the sifted flour mixture to your wet batter. Using a spatula, gently fold the ingredients together until they are just combined. It’s important to avoid overmixing here as well, which could lead to denser brownie muffins instead of the desired fudgy texture.
Step 7: Fill the Muffin Tin
Divide the batter evenly among the prepared muffin cups, filling each about ¾ full. For an extra chocolaty touch, consider sprinkling a few chocolate chips on top of each muffin. This step adds a delightful melt-in-your-mouth experience once baked.
Step 8: Bake the Muffins
Place the muffin tin in the preheated oven and bake for 13-15 minutes. Keep an eye on your ultimate brownie muffins; when a toothpick inserted in the center comes out with moist crumbs (not wet batter), they are ready. Avoid overbaking to ensure that rich, fudgy center.
Step 9: Cool and Serve
After baking, allow your brownie muffins to cool in the pan for about 10 minutes. Then, gently transfer them to a wire rack to cool completely. This step helps set the muffins’ structure while maintaining that gooey texture that makes them so irresistible. Enjoy warm or at room temperature!

How to Store and Freeze Brownie Muffins
Room Temperature: Keep your brownie muffins in an airtight container at room temperature for up to 2 days. This ensures they’re moist and delicious for snacking.
Fridge: If you want to extend their life, store the muffins in the fridge for up to a week. Allow them to return to room temperature before serving for the best taste.
Freezer: To freeze, wrap each muffin individually in plastic wrap and place them in a freezer-safe bag. They can be stored for up to 3 months; just thaw and enjoy a fudgy treat whenever you crave it!
Reheating: For a warm, freshly baked experience, microwave cooled muffins for about 10-15 seconds. This will rejuvenate their fudgy texture and rich flavor, making these brownie muffins irresistible once again.
Make Ahead Options
These Ultimate Brownie Muffins are perfect for meal prep enthusiasts! You can prepare the batter up to 24 hours in advance by mixing all your wet and dry ingredients and storing the bowl in the refrigerator. When you’re ready to bake, simply let the batter come to room temperature for about 15 minutes before filling the muffin cups and baking. Additionally, you can pre-portion the batter into the muffin tin, cover it tightly with plastic wrap, and refrigerate for up to 3 days; just be sure to remove it from the fridge for about 30 minutes before baking to ensure they rise beautifully. This way, you’ll enjoy decadent brownie muffins just as delicious as if made fresh!
Expert Tips for Brownie Muffins
-
Whisk Eggs Properly: Ensure you whisk the eggs and sugar until thick and pale to achieve a light rise; under-whisking may lead to sinking muffins.
-
Monitor Baking Time: Start checking for doneness at the 13-minute mark. Overbaking can rob your brownie muffins of their signature fudgy texture.
-
Skip the Overmixing: When combining ingredients, mix until just combined. Overmixing can lead to denser muffins rather than the desired rich, fudgy finish.
-
Use Quality Liners: Opt for silicone muffin pans or high-quality liners. This choice prevents sticking and ensures perfect release without mess.
-
Add Your Touch: Don’t hesitate to experiment! Swirl in peanut butter or add chocolate chips for a delightful twist on these brownie muffins.

- Flavored Extracts: Experiment with flavored extracts like mint or almond to customize the taste profile and bring a refreshing twist. The ideas are limitless!
- Gluten-Free Option: Swap all-purpose flour for a gluten-free blend. Just be mindful that the texture might vary, but the chocolate flavor will still shine through.
- Cocoa Alternatives: Use natural cocoa powder instead of Dutch-process for a lighter color and slightly different flavor note. It’s a subtle but interesting alteration!
- Sugar Swaps: Replace granulated sugar with coconut sugar for a deeper caramel-like flavor, but be aware it will change the muffins’ sweetness.
- Spicy Kick: Add a pinch of cayenne pepper or cinnamon to the batter for an unexpected, delightful kick that pairs beautifully with chocolate.
