Many of the I Love Foodies original recipes allow for specific dietary plans, whether that be vegan, low carb, or gluten-free. Since oat flour is naturally gluten-free, this is a great alternative if you’re cutting down on gluten or suffer from gluten intolerance. Note, though, that not all oats are recommended if you suffer from celiac disease, so please check with your doctor or health care practitioner if you are celiac.

We do have a few cake and dessert recipes that were created by a home baker suffering from celiac, and we’d suggest you check these out as well. Our recommendation? This delicious Espresso Chocolate Muffins recipe.

Why Oat Flour?

Oat flour is a nutrient-dense flour made from grinding oats into a fine powder. You can buy oat flour at most outlets but you can also easily make it yourself in a food processor or with a blender, using quick-cooking oats or rolled oats. Many health-conscious recipes use coconut flour, almond flour, or oat flour. The first two are common in low carb recipes but oat flour is higher in carbohydrates. It is much more cost-effective though.

As with coconut and almond flour, oat flour cannot simply replace all-purpose flour in recipes. This is because most cake, cupcake, bread, and muffin recipes need gluten to rise. It works great, though, with specific oat flour recipes. Sometimes the oat flour can affect the taste and texture of the baked goods, resulting in a more nutty flavour and more dense texture.

Oats generally are often recommended for their nutritional properties and have numerous health benefits. These include:

  • Incredibly nutritious
  • Rich in antioxidants
  • Contain soluble fibre, beta-glucan, which is great for gut health
  • May lower cholesterol levels
  • Can improve blood sugar control
  • Nutrient-dense and very filling, which may help with weight control

Plant-Based Alternatives

While many of our original recipes are fully plant-based, this oat flour cake recipe includes both eggs and honey. Some vegans do choose to include these in their diets, but many don’t. We do have some fully plant-based cake and dessert alternatives though. Why not try a delicious vegan banoffee pie, served with a miso date caramel, make vegan chickpea fudge, or try your hand at a South African national dish, the praised milktart?

Raw Cake Ingredients: Lemon, Honey, Eggs, Oat Flour, Cinnamon, Rose Petals, Pistachios

Oat flour cake ingredients

Mortar and Pestle with Crushed Pistachios and Dried Edible Rose Petals by Buy Whole Foods Online



  • 150g oat flour
  • 5 eggs
  • 1 tbsp organic Ceylon cinnamon
  • 3 tbsp raw honey
  • Zest of 1 lemon
  • 75g coconut sugar
  • 1 tsp baking powder
  • 30g pistachios for garnishing
  • 5g dried rose petals for garnishing (depending on preference)

Honey drizzle:

  • 1 lemon
  • 70g raw honey(as above)
  • 100ml water


  1. Preheat the oven to 180ºC. Grease a cake pan with margarine/butter (or plant-based alternative) and sprinkle with flour or cinnamon.
  2. With an electric mixer (set to medium speed), beat the eggs together with the sugar and the lemon zest until you obtain a creamy dough. Add the honey and the cinnamon and beat for 2 to 3 minutes until incorporated. Reduce the mixer speed to low, add the flour mixed with the baking powder, and beat until you get a creamy mixture.
  3. Pour the mixture into the prepared pan and bake until a toothpick inserted in the centre comes out clean; about 30 to 35 minutes (the time depends on the oven).
  4. Remove the cake from oven and un-mould on to a plate. Let cool completely.
  5. Make honey drizzle: Combine all ingredients in a small pot and bring to boil. Then, slowly let simmer until reduced and syrup-like.
  6. Add the hot honey drizzle to cooled cake to increase flavour and moisture or cold drizzle to the hot cake (better and faster absorption). Let it absorb for 10-15mins and then sprinkle with dried rose petals and roasted pistachios.
