Lemon and Poppy Seed Cake

This is from Ottolenghi cookbook and it's absolutely divine

3 large eggs, 1 cup plus 2 tablespoons (225 grams) granulated sugar, 1/2 cup (120 milliliters) heavy cream, 5 tablespoons (70 grams) unsalted butter, cubed, plus extra for greasing, 1 tablespoon poppy seeds, finely grated zest of 3 lemons (1 tablespoon), 1 1/3 cups (170 grams) all-purpose flour, 1 1/4 teaspoons baking powder, 1/4 teaspoon salt, 3/4 cup (90 grams) confectioners' sugar, sifted, 2 tablespoons lemon juice 

Heat the oven to 350° (180° C). Grease the loaf pan and line with parchment paper, then set aside.
Place the eggs and granulated sugar in the bowl of an electric mixer fitted with the paddle attachment and beat on medium-high speed for about 2 minutes, until pale and frothy. Add the cream and continue to beat for about 2 minutes, until the mixture has combined, thickened a little, and turned pale.
In the meantime, melt the butter in a small saucepan over low heat, stir in the poppy seeds and lemon zest, and set aside.
Sift the flour, baking powder, and salt together into a bowl, then use a rubber spatula to fold this into the egg mixture before folding in the butter, poppy seeds, and zest.
Spoon the mixture into the loaf pan(s) so that it rises three-quarters of the way up the sides. Place on a baking sheet and bake for about 50 minutes, or until a skewer inserted into the center comes out clean.
To make the glaze, whisk the confectioners' sugar with the lemon juice in a bowl.
Pour the glaze over the top of the cake as soon as it comes out of the oven, spreading it over the top so that it sinks in and creates a nice coating. Set aside to cool for 30 minutes before removing from the pan. Leave to come to room temperature before serving.
