Have you ever tried Madeira Cake? It's a traditional British and Irish butter cake or sponge cake that's flavored with fresh lemon zest or orange zest.

In my low-carb version I replaced flour with almond flour, and used low-carb sweetener instead of sugar. This keto-friendly coffee cake is one of the easiest desserts. Best of all, one slice has just 4 grams of net carbs and less than 300 calories!

In many ways my low-carb version is similar this American-style Keto Pound Cake which is just as easy and delicious!

You can eat this cake alone or with some fluffy whipped cream. Madeira cake also makes the perfect base for a traditional English Trifle — stay tuned for my keto-approved recipe!

Ingredients (makes 10 servings)


  1. Preheat oven to 150 °C/ 300 °F (fan assisted), or 170 °C/ 340 °F (conventional) and line a loaf pan with parchment paper.
  2. Remove the butter from the fridge so it can reach room temperature. Measure out all of the ingredients. Note: You can use 8 inch or 9 inch (20 or 23 cm) loaf pan. The more the batter spreads (wider, larger pan), the shorter the baking time. A smaller, deeper cake loaf pan will result in a higher rise. Low-Carb Madeira Cake
  3. Add the baking powder to the bowl with almond flour and mix to combine.
    Note: Instead of baking powder you can use a combination of baking soda and cream of tartar, or baking soda and lemon juice. Conversion: 1 tsp baking powder = 1/2 tsp cream of tartar (or 1 tsp lemon juice added to wet ingredients) + 1/4 tsp baking soda. Low-Carb Madeira Cake
  4. Place the softened butter in a mixing bowl. Add the sweetener and using a hand mixer or a stand mixer, beat until smooth. Add the lemon zest and vanilla extract. Add the eggs and beat until well combined. Do not worry if it splits at this point.
  5. Add the almond flour while beating, a tablespoon at a time, until smooth dough forms. Low-Carb Madeira Cake
  6. Transfer to the lined loaf pan and use a rubber spatula to spread evenly. Place in the oven and bake for 50 to 60 minutes, rotating the pan halfway to ensure even browning. Low-Carb Madeira Cake
  7. Remove from the oven and let it cool down to room temperature before removing from the pan. Slice and serve. Store at room temperature for up to two days or in the fridge for up to a week. Freeze for longer storage (up to 6 months). Low-Carb Madeira Cake

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.
