Olive oil cakes are naturally unfussy — lightly sweet, quick to mix, generous in crumb. Here, sourdough discard is whisked into the batter, giving the cake a soft, fluffy texture it wouldn’t otherwise have. Berries, blooms, cream — a soft finish that shifts easily with the season.
Notes:
This olive oil cake is light and fluffier than my go to. It works really well in a layer cake.
Vanilla extract or citrus zest can be added for more flavor. You can also swap out the milk for sour cream or crème fraîche for a richer cake.
