Just in time for Valentine's day, this mini keto heart cake is full of healthy ingredients including coconut flour, acacia fiber, and cocoa powder. If you don’t have a heart cake mold you can fashion one out of tinfoil or use a heart-shaped cookie cutter placed on top of a piece of parchment paper or a baking mat.
Coconut Flour For Keto Cakes
When making any keto cake, or baking anything keto, ingredients matter. I have used coconut flour for this cake base because it is much lower in calories and healthier than almond flour. Besides having many calories, almond flour is high in omega 6 fats, which for some of us can throw off our Omega 3:6 ratio. You cannot substitute any flour for the coconut flour in this recipe.
If you have a copy of my cookbook, The Keto Cupcake Cookbook, you know precisely why coconut flour is my top choice for keto cake. In the cookbook, I also talk about different sugar substitutes and when to use each one. If you'd like to order the cookbook, use the coupon code TARAKETO to save 10% off your entire purchase.

Choosing A Granulated Sugar Substitute
Our favorite sugar substitutes for this mini keto heart cake, in order of preference, include:
- BochaSweet, granulated or powdered
- Lakanto's Monk Fruit Blend, original, granulated
- Lakanto's Monk Fruit Blend, powdered (½ the amount)
- Lakanto's Monk Fruit Liquid Sweetener (15-30 drops)
- Liquid Stevia (15-30 drops)
- Allulose + 10 drops liquid Stevia
Tips For Baking With Sugar Substitutes
If you struggle to get the granulated sugar substitute to dissolve, powder it. You can powder any granulated sugar substitute in your kitchen with any blender. We use our magic bullet or pull out our Vitamix for even finer powdered sugar.
BochaSweet has the closest taste to sugar and measures cup for cup. It also makes the softest cakes with the perfect texture. Lakanto's Monk Fruit Blends are also delicious as they are a blend of two sugar substitutes - monk fruit and erythritol.
We have Lakanto's sugar substitute original blend, golden blend, and powdered (which is 2x as sweet as sugar) in our pantry at all times. Note that their powdered blend is 2x as sweet as sugar; reduce the sweetener in any recipe in half. If you'd like to try them out, order directly through their website and use coupon code TARAKETO for 20% off your purchase.
Liquid stevia or monk fruit can be used individually or, my preference, half of each. We find a range of 15-30 drops works well in the mini keto heart cake. However, be sure to taste-test your batter and add drops to get to your desired sweetness level.
Lakanto's Monk Fruit Blend is a blend of erythritol and monk fruit, and the original blend measures cup for cup to sugar. However, their powdered blend is 2x as sweet as sugar; reduce the amount of sweetener in any recipe in half.
When using allulose, it is only about 70% as sweet as sugar, so we add liquid stevia drops until we are happy with the sweetness level. Be careful baking with allulose because it browns rapidly. You may even need to drop your oven temperature by 25 degrees.

Frostings For Your Mini Keto Heart Cake
There are many keto-friendly ways to dress up your mug cake. You can use a sprinkle of Lakanto's Monk Fruit Powdered blend, top it with Lakanto's Sugar-Free Chocolate Chips or Whole Foods Sugar-Free Chocolate chips, or make any of our keto frosting recipes from The Keto Cupcake Cookbook. We have a few frosting recipes on our blog you can make as well.
Easy Chocolate Ganache
Combine ⅛ cup sugar-free chocolate chips with ⅛ cup heavy cream or coconut cream in a glass measuring cup or microwave-safe bowl. Heat in 20 second increments, stirring in between until chocolate is melted and ganache is formed. Spread ganache over the cake and either allow it to set up or enjoy right away.
Creamy Keto Glaze
You can also create an easy glaze for your mini keto heart cake by combining 1 Tablespoon powdered sugar substitute and 1 Tablespoon warm (almost hot) unsweetened almond milk, coconut milk, or heavy cream and ⅛ teaspoon vanilla, and a dash of salt. Whisk until the sugar substitute has dissolved and drizzle over your cake. To make a chocolate glaze, add 1 teaspoon cocoa powder into the hot milk and taste to see if it’s sweet enough.
Homemade Whipped Cream
Finally, you can make a small batch of homemade whipped cream if you have a milk frother. Combine 2 Tablespoons of heavy cream and ⅛ teaspoon vanilla and whisk until soft peaks form. Optionally, add a few drops of liquid stevia drops or Lakanto's liquid monk fruit drops to sweeten the mixture. We prefer liquid options because heavy cream whips best when cold, and granulated sugar substitutes don't like to dissolve well in cold liquids.

- 1 teaspoon acacia fiber powder or a pinch of xanthan gum
- ¼ teaspoon baking soda
