This keto chocolate cake is a perfect choice when you want something chocolatey and indulgent but without kicking yourself out of ketosis. It satisfies sweet cravings with rich flavors and a smooth chocolate glaze that truly feels special without the carbs.

I first made this after experimenting with various low-carb flours and sweeteners and it quickly became a staple for birthdays and holidays in my keto household.

Ingredients

  • Almond flour: provides a moist, nutty base and choosing a fresh batch ensures maximum flavor and freshness
  • Unsweetened cocoa powder: offers deep chocolate notes; opt for high quality unsweetened cocoa for the best taste
  • Coconut flour: helps with structure and adds a subtle sweetness; be precise in measuring as it absorbs liquid differently
  • Arrowroot starch: lends a light texture, making the cake less dense
  • Baking powder and baking soda: create lift for a tender crumb
  • Xanthan gum: acts as a binder to keep the cake from crumbling, essential in gluten-free baking
  • Salt: balances and enhances all the sweet and chocolate flavors
  • Warm almond milk or heavy cream: reacts with vinegar to create a buttermilk effect for a tender crumb, using fresh almond milk improves taste
  • Coconut oil: adds healthy fats and moisture; use virgin for a subtle coconut hint or refined for milder flavor
  • Powdered monkfruit erythritol and Sukrin brown sugar sweetener: combine for sweetness that does not spike blood sugar; using a mix balances flavor and texture
  • Room temperature eggs: help the batter come together smoothly
  • Vanilla extract: rounds out the flavor with a warm aroma
  • Heavy cream, chocolate chips sweetened with stevia, butter, vanilla and salt: make the luscious glaze that ties everything together

Instructions

Build The Dry Mix:
Whisk together almond flour, cocoa powder, coconut flour, arrowroot starch, baking powder, baking soda, xanthan gum and salt in a bowl until evenly combined. This evenly distributes the rising agents and gums and makes sure the chocolate is fully incorporated.
Make The Buttermilk Substitute:
In a small bowl, stir warm almond milk or heavy cream with the white vinegar and set aside briefly. This acid reaction helps with tenderizing the crumb in absence of regular buttermilk.
Whisk The Wet Ingredients:
In a larger bowl, whisk coconut oil, powdered monkfruit erythritol, Sukrin brown sugar, eggs and vanilla extract until smooth and pale. Then incorporate your buttermilk substitute and whisk again until fully combined with no lumps.
Combine Wet And Dry:
Pour the dry ingredients into the wet mixture and stir gently with a spatula or spoon until a thick, smooth batter forms. Be careful not to overmix to keep the cake tender.
Prepare And Bake:
Grease an 8-inch cake pan thoroughly and scrape batter into the pan. Smooth the top evenly. Bake in a preheated oven at 330 Fahrenheit for 40 to 45 minutes. The cake should pull away slightly from the pan edges and a toothpick inserted into the center comes out clean or with very few moist crumbs.
Cool And Release:
Let the cake cool completely in the pan before carefully turning it out onto a plate. Gently jiggle the pan a little to loosen the cake sides before flipping to avoid breakage.
Make The Chocolate Glaze:
Place the stevia sweetened chocolate chips and butter in a heatproof bowl. Warm the heavy cream until almost boiling and pour it over the chocolate and butter. Let stand about 40 seconds. Stir until melted and smooth then add vanilla extract and a pinch of salt to balance the sweetness and deepen the flavor.
Glaze The Cake:
Pour the glaze over the cooled cake and spread evenly with a spatula. Let the glaze set for a bit to achieve a shiny, smooth finish. Add toppings like chopped nuts or keto-friendly sprinkles if you like.

My favorite ingredient has to be the combination of powdered monkfruit and Sukrin brown sugar sweetener. It has the sweetness you expect from sugar but without any bitterness or aftertaste I encountered using one sweetener alone. This cake always sparks memories of cozy weekends spent baking with my kids, smelling rich chocolate filling the kitchen.

Storage Tips

Store leftovers in an airtight container at room temperature for up to two days or in the refrigerator for up to a week. For longer storage wrap slices tightly in plastic wrap then freeze in a zip-top bag for up to three months. Thaw slices at room temperature or warm gently in a microwave before serving.

Ingredient Swaps

Coconut oil can be swapped with unsalted butter for a richer flavor but increases dairy content. Replace almond milk with any unsweetened nut milk if preferred but fresh almond milk enhances flavor best. Xanthan gum can be replaced with guar gum in equal quantity though texture may vary slightly. For the glaze, use sugar-free dark chocolate chips if you want a less sweet finish.

Serving Ideas

Serve with a dollop of whipped cream or a few fresh berries for a contrast in textures and flavor brightness. Pair alongside coffee or herbal tea for a satisfying afternoon treat. Add a sprinkle of toasted nuts or shaved unsweetened chocolate on top for a professional touch.
