These Brownie Bites with Chocolate Truffle Filling feature a fudgy brownie shell and rich chocolate center. Perfect for weddings, baby showers, birthdays, dessert tables, and holiday parties.

Is it a Brownie. . .or is it a Truffle?

It's both, my friend. It's both.

If you've spent any time here at Out of the Box Baking, you know I've developed a real love for miniature desserts. From petit fours and macarons to mini layer cakes and cheesecake cups, there's something special about bite-sized treats that are easy to serve and even easier to enjoy.

These Brownie Bites with Chocolate Truffle Filling may be one of my favorite creations yet.

They start with a simple chocolate cake mix and bake up into soft, fudgy brownie bites with deep centers perfect for filling. Once cooled, each brownie bite is piped full of rich chocolate truffle filling and decorated to suit the occasion.

Whether you're planning a wedding dessert table, bridal shower, baby shower, birthday party, graduation celebration, anniversary party, church reception, or holiday gathering, these little treats fit right in.

They're elegant enough for special events but simple enough for everyday baking.

Ingredients

You will find a full printable recipe card at the bottom of this post but here's a peek at what you're going to need to make these delicious brownie bites. These are simple ingredients, since this recipe starts with a box of cake mix.

For the Brownie Bites

• 1 box Devil's food or dark chocolate/fudge cake mix
• 2 large eggs, room temperature
• ½ cup butter, softened/beaten
• 1 - 2 tablespoons water
• ⅔ cup chocolate chips
• 1 teaspoon vanilla extract

For the Chocolate Truffle Filling

• 1 ¼ cups semi-sweet chocolate chips
• ⅓ cup heavy whipping cream

Optional Decorations

• Chocolate drizzle
• White chocolate drizzle
• M&M candies
• Candy pearls
• Sanding sugar
• Holiday sprinkles
• Crushed cookies
• Chopped nuts with caramel drizzle

How to Make Brownie Bites with Chocolate Truffle Filling

Preheat oven to 350 degrees Fahrenheit.

Generously spray a mini muffin pan with baking spray.

Cream room temperature butter until light and fluffy.

Add vanilla, cake mix, eggs, and water. Beat until combined. Add chocolate chips.

The batter will be thicker than a typical cake batter, but thinner than cookie dough. It should still be soft enough to scoop.

Using a small cookie scoop, fill mini muffin wells about two-thirds full.

Bake for 10 to 11 minutes. The top should appear baked but the inside might still have a bit of a jiggle. That's what you want.

As soon as the brownie bites come out of the oven, allow them to cool for about three minutes. You might notice that they start to settle in the centers a bit. That's totally fine.

Use the handle of a wooden spoon, tart tamper, or similar tool to gently press down the center of each brownie bite to create a well. (I used a small fondant roller, which is the perfect size.)

Repeat this process on all brownies.

Allow the brownie bites to cool completely in the pan.

Run a thin knife around the edges if necessary before removing.

Make the Truffle Filling

Place chocolate chips in a microwave-safe bowl. Heat heavy cream until hot but not boiling.

Pour over chocolate chips and allow the mixture to sit for several minutes.

Stir until smooth and glossy.

Allow the filling to cool slightly until thick enough to pipe.

Transfer to a piping bag and fill each brownie bite.

Decorate as desired. See the note below about some fun decorating options!

Perfect for Every Celebration

One of the things I love most about this recipe is how easily it adapts to different events.

• For weddings and bridal showers, decorate with white chocolate drizzle and candy pearls.
• For baby showers, use pastel-colored drizzles and sprinkles.
• For birthday parties, top with M&Ms, candies, or colorful sanding sugar.
• For anniversaries and Valentine's Day, use red and pink decorations.
• For Christmas, add festive sprinkles or crushed peppermint candies.

The possibilities are endless.

Frequently Asked Questions

Can I make these brownie bites ahead of time?

Yes. These are excellent make-ahead desserts and often taste even better the following day.

Absolutely. Store in an airtight container and freeze for up to three months.

What kind of chocolate cake mix should I use?

Choose from Devil's food, chocolate fudge, German Chocolate, or even red velvet cake mix. All will work well.

Why do I press the centers while they're hot?

The brownie bites are easiest to shape immediately after baking. Just make sure you leave the brownies in the pan after shaping until they're fully cooled.

What chocolate should i use in the filling?

I used milk chocolate but you can use semi-sweet, dark chocolate, or even mint chocolate chips.

How do I keep them from sticking?

Use baking spray and allow them to cool completely before removing from the pan.

Can I make these for weddings and showers?

Yes! They're the perfect bite-sized desserts for dessert tables and special events.

Can I use a different filling?

Absolutely. Cheesecake, peanut butter, caramel, marshmallow, and cookies-and-cream fillings all work beautifully.

How should I store them?

Store in an airtight container at room temperature for several days or refrigerate for up to one week.

Can I decorate them in advance?

Yes. Decorate several hours ahead or even the day before serving.

How to Store Brownie Bites with Chocolate Truffle Filling

Store leftover brownie bites in an airtight container at room temperature for up to 3 days.

For longer storage, refrigerate them for up to one week. Allow chilled brownie bites to sit at room temperature for 15–20 minutes before serving for the best texture and flavor.

Because the filling contains heavy cream, refrigeration is recommended if you're making them more than a day in advance or serving them at an event later in the week.
