Grapefruit–Poppy Seed Loaf Cake with Yogurt Glaze

Recipe Description

We’ve all heard of the traditional lemon and poppy seed combination, but this Grapefruit–Poppy Seed Loaf Cake with Yogurt Glaze takes it up a notch. I love any citrus flavored cakes so this loaf cake is a real winner in my book. This is a simple recipe which you can bake up for morning coffee or afternoon tea!

It’s simple to make too – start by mixing the dry ingredients together. Combine the grapefruit zest with the granulated sugar before mixing in eggs, oil, and vanilla. Alternate adding dry ingredients and yogurt to the wet ingredients to make a cake batter. Place the batter in a loaf tin and bake it. Drizzle over a yogurt glaze and sprinkle with poppy seeds.
