Preheat the oven to 350°F. Grease a 9” x 13” baking tray with butter and dust with flour.
In a large bowl, whisk together eggs, oil, marmalade, Hedessent Crispy Doughnut and Tahitian Bean flavour drops, and sour cream until just combined.
Add sugar, all-purpose flour, cake flour, salt, baking powder, and cinnamon to the wet ingredients. Mix well to form a thick, smooth batter.
Pour the batter into the prepared baking tray and bake for 30 minutes, or until a skewer inserted into the center comes out clean or with a few small crumbs.
Cool the cake on a wire rack for at least 30 minutes. Once cool, use a 3” round cutter (or shape of your choice) to cut out cake rounds. Let them cool further on a wire rack.
