How to Make Boston Cream Brownies

Step 1: Bake the Brownies

Preheat oven to 350°F (175°C).

Line a 9×9-inch baking pan with parchment paper.

In a bowl, whisk melted butter and sugar.

Add eggs and vanilla; mix well.

Stir in cocoa powder, flour, and salt until combined.

Spread batter evenly in pan.

Bake for 30–35 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs.

Cool completely.

Step 2: Prepare the Vanilla Cream Layer

Whisk vanilla pudding mix and cold milk until thickened.

In a separate bowl, whip heavy cream to soft peaks.

Fold whipped cream into pudding until smooth and fluffy.

Spread evenly over cooled brownies.

Refrigerate for 30 minutes to firm up.

Step 3: Make the Ganache

Heat heavy cream until just simmering.

Pour over chocolate chips and let sit for 2–3 minutes.

Stir until smooth and glossy.

Pour ganache over vanilla layer and spread evenly.

Step 4: Chill & Slice

Refrigerate for at least 1 hour until ganache sets.

Lift from pan using parchment and slice into squares.
