Step 1
Preheat oven to 350°F (177°C). Lightly grease and line a half baking sheet (18 x 13 inch) with parchment paper.
Step 2
In a medium bowl, whisk together the flour, baking powder, salt, and baking soda until well mixed.
Step 3
Combine the Redpath® Granulated Sugar, the Redpath® Golden Yellow Sugar, and lemon zest in a medium bowl. With the back of a spoon, rub the lemon zest into the sugars until fragrant. Mix until thoroughly combined.
Step 4
In a bowl of stand mixer, using the paddle attachment, cream together butter and the lemon-sugar mixture until light and fluffy; at least 3 minutes.
Step 5
Add eggs, one at a time, beating well until egg is fully incorporated after each addition. Scrape down the sides of the bowl every so often with a rubber spatula.
Step 6
Add in milk, lemon juice, vanilla extract, and if using, lemon extract. Mix until completely blended.
Step 7
Remove the bowl from the stand mixer. Sift the dry ingredients over the batter. With the rubber spatula, fold in the dry ingredients until no flour streaks remain.
Step 8
Transfer the batter to the prepared baking sheet. With a large offset spatula, evenly spread the batter to the edges of the pan. Run a thumb around the edge of the baking sheet and the batter to check the depth and evenness of the batter; also to prevent cake from sticking to the edges.
Step 9
Bake for 15 to 20 minutes, or until the cake springs back when gently pressed. Cool completely in the pan.
Step 10
Once cake is completely cooled, use an 8-inch plate or a cake pan (or the size of the trifle dish or glass bowl) and a sharp paring knife, to cut out two rounds. (See Chef’s Tips)
