Ingredients Needed
This recipe uses simple, wholesome ingredients that come together to create the perfect balance of flavor and nutrition. Here’s what you’ll need:
For the Cupcakes:
- 1 cup almond flour (fine-ground for best texture)
- 1/3 cup unsweetened cocoa powder (Dutch-processed preferred for richer flavor)
- 1/3 cup granulated erythritol or monk fruit sweetener
- 1/4 tsp salt
- 1 tsp baking powder
- 1/2 cup unsalted butter, melted
- 2 large eggs, room temperature
- 1/4 cup unsweetened almond milk
- 1 tsp vanilla extract
For the Frosting:
- 1/2 cup unsalted butter, softened
- 1/3 cup powdered erythritol
- 2 tbsp unsweetened cocoa powder
- 1 tsp vanilla extract
- 2 tbsp heavy cream
For Decoration:
- Sugar-free chocolate chips
- Black food coloring (gel-based works best)
- Unsweetened shredded coconut
- Yellow or green sugar-free candy eyes
Don’t forget, you can always swap out certain ingredients based on your dietary needs. Use coconut flour instead of almond flour for a nut-free option, or experiment with natural food coloring alternatives!
Equipment Needed
- Muffin tin or cupcake pan
- Paper cupcake liners
- Mixing bowls (at least two)
- Hand mixer or stand mixer
- Rubber spatula
- Measuring cups and spoons
- Piping bag with round or star tip (or use a zip-top bag with the corner snipped off)
If you don’t have a piping bag, no worries—a simple plastic zip-top bag works just fine. Just snip off a corner and you’re good to go. And if you don’t have paper liners, grease your muffin tin generously with butter or coconut oil to prevent sticking.
Preparation Method
- Preheat your oven to 350°F (175°C). Line your muffin tin with paper cupcake liners.
- In a large mixing bowl, whisk together the almond flour, cocoa powder, erythritol, salt, and baking powder. This ensures an even distribution of dry ingredients.
- In a separate bowl, mix the melted butter, eggs, almond milk, and vanilla extract. Make sure the butter isn’t too hot to avoid scrambling the eggs!
- Slowly pour the wet ingredients into the dry ingredients, stirring until just combined. Be careful not to overmix—this can make the cupcakes dense.
- Divide the batter evenly among the cupcake liners, filling each about 2/3 full.
- Bake for 18–22 minutes, or until a toothpick inserted into the center comes out clean. Let the cupcakes cool completely on a wire rack before decorating.
- For the frosting, beat the softened butter with a hand mixer until creamy. Gradually add powdered erythritol and cocoa powder, mixing well after each addition.
- Add vanilla extract and heavy cream, then mix until the frosting is light and fluffy. If needed, add more heavy cream, one teaspoon at a time, to reach your desired consistency.
- Add black food coloring to the frosting and mix thoroughly until you achieve the desired shade of black.
- Pipe the frosting onto the cooled cupcakes using a piping bag or zip-top bag. Start with a circular motion to create the “fur” of the black cat.
- Decorate each cupcake with sugar-free candy eyes, chocolate chips for the ears, and shredded coconut for whiskers.
- Serve immediately or store in an airtight container in the refrigerator for up to 5 days.
Cooking Tips & Techniques
- Room Temperature Ingredients: Make sure your eggs and butter are at room temperature for a smoother batter.
- Don’t Skip the Sifting: Sifting the dry ingredients ensures there are no lumps and makes for fluffier cupcakes.
- Test for Doneness: Insert a toothpick into the center of a cupcake—if it comes out clean, they’re done!
- Use Gel Food Coloring: Liquid food coloring can alter the consistency of your frosting. Gel coloring works best for deep, vibrant colors.
- Decorating Hack: If you don’t have candy eyes, use a tiny dollop of white frosting and add a dot of melted chocolate or black food coloring for pupils.
Remember, practice makes perfect! If your first batch of black cat faces doesn’t turn out picture-perfect, don’t sweat it. They’ll still taste amazing, and you’ll improve with each try.
Variations & Adaptations
- Nut-Free Option: Swap almond flour for sunflower seed flour or coconut flour (adjust measurements accordingly).
- Seasonal Twist: Add a pinch of pumpkin spice to the cupcake batter for a fall-inspired flavor.
- Dairy-Free Version: Use coconut oil and dairy-free cream for the frosting, and swap almond milk with coconut milk.
- Different Themes: Instead of black cats, decorate the cupcakes as pumpkins, ghosts, or even bats!
- Sweetness Customization: Adjust the amount of sweetener to match your taste preferences.
One variation I love is swapping the black cat design for little ghost cupcakes. By using white frosting and chocolate chips for eyes and mouths, you can create an equally adorable (and spooky) alternative!
Serving & Storage Suggestions
Serve these Black Cat Keto Cupcakes at room temperature for the best flavor. Pair them with a warm mug of keto-friendly hot chocolate, or serve alongside a platter of other spooky treats like sugar-free gummy worms or pumpkin-flavored fat bombs.
Store the cupcakes in an airtight container in the refrigerator for up to 5 days. If you need to prepare them in advance, you can freeze the unfrosted cupcakes for up to one month. Once ready to serve, let them thaw completely, frost, and add decorations.
To reheat, simply let the cupcakes come to room temperature naturally—avoiding the microwave to keep the frosting intact.

FAQs
Can I use coconut flour instead of almond flour?
Yes, but coconut flour tends to absorb more liquid, so you’ll need to adjust the amount. Use about 1/3 cup of coconut flour and increase the eggs to three for best results.
Can I make these cupcakes ahead of time?
Absolutely! You can bake the cupcakes up to two days in advance and store them in an airtight container. Frost and decorate them just before serving for the best presentation.
What can I use if I don’t have black food coloring?
No problem! You can mix equal parts blue, red, and green food coloring to create black. Just make sure to use gel-based colors for the richest hue.
Are these cupcakes safe for kids?
Yes, they’re sugar-free and low-carb, making them a healthier option for kids. Just be mindful of any potential allergies to nuts, dairy, or other ingredients.
What’s the best way to store leftover cupcakes?
Store leftover cupcakes in an airtight container in the refrigerator for up to five days. For longer storage, keep them unfrosted in the freezer for up to one month.
