Let’s create this unique Strawberry Bliss dessert:

1. Make the Choux Pastry Base:

Preheat oven to 400°F (200°C). Grease a 15x10x1-inch baking pan and line it with parchment paper; grease the paper as well.

In a large saucepan, bring the 1 cup of water and the cubed butter to a rolling boil over medium-high heat.

Remove the pan from the heat. Add the flour all at once. Beat vigorously with a wooden spoon until the mixture is blended and forms a smooth ball, pulling away from the sides of the pan.

Return the pan to medium heat. Cook, stirring constantly, for about 1 minute to dry out the paste slightly.

Remove from heat again and let the paste stand for 5 minutes to cool slightly.

Add the eggs, one at a time, beating very well with an electric mixer (or vigorously by hand with the wooden spoon) after each addition until the egg is fully incorporated and the dough is smooth and shiny.

2. Bake the Choux Base:

Spread the choux pastry dough evenly into the prepared 15x10x1-inch baking pan.

Bake for 20-25 minutes, or until the pastry is puffed, golden brown, and feels dry to the touch. The surface will likely be uneven and bumpy – this is normal for choux baked flat.

3. Cool the Base:

Cool the baked choux base completely in the pan on a wire rack.

4. Make the Creamy Filling:

In a large bowl, beat the softened cream cheese, confectioners’ sugar, and strawberry jam with an electric mixer until smooth.

Gradually beat in the cold milk and the instant vanilla pudding mix until the mixture is smooth and starts to thicken.

5. Prepare Whipped Cream:

In a separate small bowl, beat the ½ cup heavy whipping cream until stiff peaks form. (Add vanilla here if desired).

6. Combine Filling:

Gently fold the whipped cream into the cream cheese/pudding mixture until evenly combined.

7. Assemble the Dessert:

Spread the prepared filling evenly over the completely cooled choux pastry base in the pan.

8. Chill:

Refrigerate, covered, for at least 1 hour, or until the filling is well-chilled and slightly set.

9. Top and Serve:

Just before serving, arrange the quartered fresh strawberries over the top of the chilled filling.

Slice into squares or rectangles and serve immediately. Enjoy your Strawberry Bliss
