Carrot Apple Oat Cake
A moist, lightly spiced snacking cake built on rolled oats and grated carrot, with apple folded in for sweetness and a tender crumb. Toasted walnuts and a hint of orange zest give it a warmer, more grown-up character than the usual version, and the oats are partly ground so the cake holds together without turning heavy.

Whole recipe (8 servings): 3136 kcal
- 1 1/4 cups rolled oats (not instant)
- 1 cup all-purpose flour
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon fine salt
- 1 1/2 teaspoons ground cinnamon
- 1/2 teaspoon ground ginger
- 1/4 teaspoon freshly grated nutmeg
- 2 large eggs, at room temperature
- 3/4 cup packed light brown sugar
- 1/2 cup neutral oil, such as sunflower or canola
- 1/2 cup plain whole-milk yogurt
- 1 teaspoon finely grated orange zest
- 1 teaspoon vanilla extract
- 1 1/2 cups coarsely grated carrot (about 2 medium carrots)
- 1 cup peeled and coarsely grated apple (about 1 large apple)
- 3/4 cup chopped walnuts, toasted and cooled
- 2 tablespoons rolled oats, for the top (optional)
Method
8 steps- Heat the oven to 350°F (175°C). Grease a 9-inch round cake pan or an 8-inch square pan, line the base with parchment, and grease the parchment.
- Pulse 1 cup of the rolled oats in a food processor or blender until they resemble coarse sand, with some whole flakes remaining. Tip into a large bowl and whisk in the flour, baking powder, baking soda, salt, cinnamon, ginger, and nutmeg.
- In a second large bowl, whisk the eggs with the brown sugar until smooth and slightly glossy, about 1 minute. Whisk in the oil, yogurt, orange zest, and vanilla until fully combined.
- Stir the grated carrot and apple into the wet mixture. Add the dry ingredients and the toasted walnuts, then fold gently with a spatula just until no dry streaks remain. The batter will be thick and slightly lumpy; do not overmix.
- Scrape the batter into the prepared pan and level the top. If using, scatter the remaining 2 tablespoons rolled oats over the surface.
- Bake on the middle rack for 40 to 45 minutes, until the top is deep golden and a skewer inserted into the centre comes out with only a few moist crumbs. Rotate the pan halfway through if your oven bakes unevenly.
- Cool the cake in the pan for 15 minutes, then turn it out onto a rack, peel off the parchment, and cool completely before slicing.
- Store in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days and bring to room temperature before serving.
Recipe notes
Helpful tips
- Toasting the walnuts for 6 to 8 minutes in the same oven while it preheats deepens their flavour; cool before folding in.
- If the batter looks stiff, add 1 tablespoon of milk or orange juice to loosen it slightly.
- A handful of raisins or dried cranberries can replace some of the walnuts for a chewier cake.
Equipment
- 9-inch round cake pan or 8-inch square pan
- Parchment paper
- Box grater
- Food processor or blender
- Two large mixing bowls
- Whisk
- Spatula
- Wire cooling rack
- Skewer or cake tester
Storage
Airtight at room temperature for up to 3 days; refrigerated for up to 5 days. Wrap tightly and freeze for up to 2 months, thawing overnight in the fridge.
Additional tips
- The cake is done when a skewer comes out with a few moist crumbs, not wet batter. Grate the apple and carrot on the coarse side of a box grater and do not squeeze them dry, as their moisture is needed. Let the cake cool fully before cutting so the crumb sets.
