Ingredient Notes

A few smart ingredient choices help these brownie bites turn out rich, soft, and perfectly balanced.

Granulated sugar
Provides sweetness and helps create that glossy brownie texture. It also contributes to the shiny top that makes brownies look bakery-quality.

Butter
Softened butter melts easily and blends smoothly with sugar and chocolate, creating a rich base.

Water
Helps dissolve the sugar and creates a smoother chocolate mixture during the melting process.

Semi-sweet chocolate chips
These form the main chocolate base. Semi-sweet works best because it balances sweetness and richness.

Egg
Gives structure and moisture while keeping the brownie bites soft and fudgy.

Vanilla extract
Enhances the chocolate flavor and adds warmth.

All-purpose flour
Provides structure without making the brownies too cakey.

Baking soda
A small amount helps the brownie bites rise slightly and stay tender.

Milk chocolate chips
These add extra sweetness and chocolate pockets inside the brownie.

Creamy peanut butter
The star filling. It creates a smooth, rich center that pairs perfectly with the chocolate.

Step-by-Step Instructions

1. Melt butter and sugar

In a microwave-safe bowl, combine:

• granulated sugar
• softened butter
• water

Microwave in 45-second intervals, stirring between each round until the butter melts and the mixture becomes hot and smooth.

2. Add chocolate

Stir in the semi-sweet chocolate chips while the mixture is still warm.

Mix until completely melted and smooth.
If needed, microwave for a few extra seconds and stir again.

The mixture should look glossy and rich.

3. Add egg and vanilla

Stir in:

• egg
• vanilla extract

Mix well until fully combined.

This step creates the classic brownie texture.

4. Add dry ingredients

Add:

• flour
• baking soda

Mix gently until smooth and thick.

Do not overmix to keep the brownie bites soft.

5. Cool the batter slightly

Let the batter rest for 5–10 minutes.

This prevents the milk chocolate chips from melting completely when added.

6. Fold in milk chocolate chips

Stir in the milk chocolate chips until evenly distributed.

The batter will be thick and glossy.

7. Prepare for baking

Preheat oven to 350°F (175°C).

Grease a muffin tray or line it with paper liners.

Fill each muffin cup about ¾ full with batter.

8. Bake

Bake for 14–16 minutes.

The tops should look set and slightly cracked, and a toothpick inserted near the edge should come out with a few moist crumbs.

Avoid overbaking to keep them fudgy.

9. Create the peanut butter center

Let the brownie bites cool for 5 minutes.

If the centers do not sink naturally, gently press the middle with the back of a spoon to create a small well.

10. Add melted peanut butter

Microwave the peanut butter in short bursts until smooth.

Spoon about 1 tablespoon into the center of each brownie bite.

Top with extra chocolate chips if desired.

Let them cool until the peanut butter thickens slightly.

Serve warm or at room temperature.

Expert Tips for Best Results

Use good-quality chocolate chips for a richer flavor and smoother texture.

Do not overbake. The edges should be set while the centers stay soft.

Allow the batter to cool slightly before adding milk chocolate chips to keep them intact.

Press the center gently while still warm to create a perfect peanut butter well.

Use a non-stick muffin pan or liners to prevent sticking.

For a bakery-style finish, sprinkle extra chocolate chips on top right after adding peanut butter.

Variations and Substitutions

Crunchy peanut butter version
Use crunchy peanut butter for added texture.

Dark chocolate brownie bites
Replace semi-sweet chocolate with dark chocolate for a deeper flavor.

Mini brownie bites

Nut-free version
Replace peanut butter with chocolate spread or cookie butter.

Salted peanut butter topping
Add a small pinch of sea salt on top for a sweet-salty contrast.

Caramel version
Drizzle caramel over the peanut butter center for extra richness.

Storage and Freezing

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

For a firmer peanut butter center, refrigerate them.

To freeze, place in a freezer-safe container and store for up to 2 months.

Let them thaw at room temperature before serving.

You can warm them slightly in the microwave for a fresh-baked taste.

Yes, but stir it well first to keep the texture smooth and creamy.
