raspberry fool with cornbread croutons

This is summer in a bowl, and I have a loose recipe to represent the season:

170 g (1 6-oz package) raspberries, 12 raspberries reserved for garnish
1/4 cup sugar
1 loaf store-bought cornbread, cubed
1 cup heavy cream
1 Tbsp powdered sugar
1/4 tsp vanilla extract
zest of 1 lemon
Mint sprigs, for garnish

1. Preheat oven to 400 degrees F.
2. Combine the raspberries (except for the 12 reserved raspberries) and the sugar in a small saucepan. Cook over low heat until the raspberries have broken down. Remove from heat and cool.
3. Place the cornbread cubes on a baking sheet and bake until toasted and light golden brown, about 5 minutes.
4. Whip the cream with powdered sugar, vanilla extract and lemon zest until stiff peaks form.
5. Stir a third of the whipped cream into the raspberry compote. Gently fold the rest of the whipped cream into the raspberry mixture.
6. Divide the cornbread croutons among four bowls. Top with the raspberry fool and garnish with three raspberries and a mint sprig.
