This refined sugar free, dairy free, and gluten free grapefruit cake is such a refreshing treat. Grapefruit is definitely underused in baking, in my opinion. This moist and delicious grapefruit cake is bursting with sweet, bright, and tangy grapefruit flavour. Enjoy a slice of this cake for dessert, breakfast, or as a nutritious snack.
Grapefruit Cake – Main Ingredients
This recipe calls for fresh grapefruit zest and juice. They add a lovely fragrance and flavour to this cake and there’s no substitute for those ingredients. Processed grapefruit juice definitely won’t give the same results.
I opted to use gluten free oat flour in this grapefruit loaf recipe. I make big batches of oat flour in my food processor (just fill your food processor with rolled oats then process for 2 minutes) so I always have oat flour on hand for my gluten free baking projects. Just be sure to by oats that are labelled gluten free if you need to avoid gluten for medical reasons.
This cake calls for extra virgin olive oil as the fat in this recipe. The warm rich flavour of the olive oil pairs nicely with the grapefruit zest and works really well in this recipe. I love baking with olive oil because it’s healthy, delicious, and affordable, but feel free to substitute any other oil (or even melted butter if you don’t need it to be dairy free).
This refined sugar free cake is sweetened with date paste. I often use date paste in cakes and muffins because it’s a nutritious sweetener with no added sugar and works well in baked goods. See my date paste recipe for instructions on making date paste. It’s easy to do – all you need is dates, boiling water, and a blender.
You can make this grapefruit cake ahead of time, slice it up and freeze it, then thaw it out at room temperature when you want an easy, on-the-go breakfast, snack, or dessert.
