Warm Introduction
If you’re anything like me, chocolate and coconut together are pure comfort food bliss. I grew up sneaking little Mounds bars whenever I could, and that chewy, coconut-filled chocolate has always been one of my guilty pleasures. But on a low-carb lifestyle, the sugar in those treats was a no-go… until I discovered this Keto Mounds Cake. It’s everything I love about the candy bar — rich chocolate, sweet coconut, creamy layers — but made completely keto-friendly. This is the kind of dessert that makes you realize healthy eating doesn’t mean missing out on indulgence.
What Makes This Recipe Stand Out
This cake isn’t your average “low-carb dessert.” It’s a full-on showstopper. You get a soft, moist chocolate cake layered with a creamy coconut filling, then finished with a silky sugar-free chocolate glaze. It’s like a Mounds bar grew up into a cake and decided to go keto. What’s more, the recipe is surprisingly simple to make — no complicated steps, no unusual ingredients you can’t find. It’s proof that decadent desserts can fit into a keto lifestyle without compromise.
Personal Blogger Note
The first time I baked this cake, I was nervous it wouldn’t live up to the memory of my favorite candy bar. But when I sliced into it and tasted that chocolate-coconut combo, I actually smiled out loud (yes, that’s a thing!). Even my non-keto friends went back for seconds. That’s when I knew this was going to be a regular in my recipe collection.
Equipment You’ll Need (and Why)
- Mixing Bowls – You’ll need a couple for separating wet and dry ingredients. I always use one large and one medium bowl to keep things organized.
- Hand Whisk or Electric Mixer – Helps ensure the batter is lump-free and fluffy. A whisk works fine, but a mixer saves time.
- Baking Pan (9×9 or round) – This is the base where your cake bakes. Greasing or lining it makes for an easier release.
- Spatula – Perfect for folding ingredients gently, scraping down the sides, and spreading the coconut filling evenly.
- Small Saucepan – Useful for melting chocolate and butter for the glaze. I find it easier than using a microwave since you can control the heat.
- Cooling Rack – To cool your cake properly before frosting. Skipping this step can make your glaze too runny.
Ingredients (with Substitutions)
For the Chocolate Cake Base:
- 1 ½ cups almond flour – Low-carb and gluten-free, with a nutty richness. Coconut flour can be used, but only ½ cup since it’s more absorbent.
- ½ cup unsweetened cocoa powder – For that deep chocolate flavor. Dutch-processed cocoa will make it darker and richer.
- ½ cup erythritol or monk fruit sweetener – Keeps it sugar-free. Stevia can also work, but adjust for sweetness.
- 1 tsp baking powder – Helps the cake rise and stay fluffy.
- ¼ tsp salt – Balances the sweetness and enhances the chocolate.
- 3 large eggs – For structure and moisture. Flax eggs are an option if you’re going egg-free.
- ½ cup unsweetened almond milk – Any low-carb milk substitute works (coconut milk adds more coconut flavor).
- ⅓ cup melted butter or coconut oil – Adds richness. I like butter for a more traditional cake taste.
- 1 tsp vanilla extract – Always adds warmth and depth.
For the Coconut Filling:
- 1 ½ cups unsweetened shredded coconut – The star of the filling. Make sure it’s unsweetened!
- ½ cup heavy cream – For a rich, creamy texture. Coconut cream is a dairy-free swap.
- 3 tbsp powdered erythritol – Keeps the filling lightly sweetened.
- 1 tsp vanilla extract – Complements the coconut perfectly.
For the Chocolate Glaze:
- ½ cup sugar-free chocolate chips – Smooth, melt-in-your-mouth finish.
- 2 tbsp butter or coconut oil – Makes the glaze glossy and easy to spread.
Step-by-Step Cooking Process
- Preheat oven to 350°F (175°C). Grease your baking pan or line it with parchment.
- Make the cake batter: In a bowl, whisk together almond flour, cocoa powder, erythritol, baking powder, and salt. In another bowl, beat eggs, almond milk, melted butter, and vanilla. Combine wet and dry ingredients until smooth.
- Bake the cake base: Pour batter into prepared pan and bake for 20–25 minutes, or until a toothpick comes out clean. Let cool completely.
- Prepare the coconut filling: In a saucepan, heat cream, erythritol, and vanilla until warm. Stir in shredded coconut and mix until thick and spreadable.
- Assemble: Spread the coconut mixture evenly over the cooled cake.
- Make the glaze: Melt chocolate chips with butter in a saucepan over low heat, stirring until silky.
- Finish: Pour the glaze over the coconut layer, spreading evenly. Refrigerate for at least 30 minutes to set before slicing.
