Ingredients & Why We Use Them
| Ingredient | Role in Recipe |
|---|---|
| Almond flour | Low-carb flour replacement; creates soft crumb and adds healthy fats. |
| Coconut flour | Lightens texture & absorbs moisture; prevents dense cupcakes. |
| Allulose | Sugar-like sweetness without carbs or glycemic impact. |
| Baking powder | Helps cupcakes rise and stay fluffy. |
| Salt | Enhances sweetness and flavor balance. |
| Eggs | Provide structure, lift, and moisture—crucial in grain-free baking. |
| Butter | Adds richness and keeps crumb tender. |
| Heavy cream | Adds fat and moisture for bakery-style texture. |
| Vanilla extract | The signature flavor of the cupcake—fragrant & classic. |
| Keystone Pantry Keto Buttercream Vanilla Frosting | Zero-net-carb, sugar-free frosting designed for piping, spreading & decorating. |
👩🍳 Step-by-Step Instructions
-
Preheat oven to 350°F (175°C). Line a 12-cup muffin tray with paper liners.
-
In one bowl, whisk almond flour, coconut flour, allulose, baking powder, and salt.
-
In a second bowl, whisk eggs, melted butter, heavy cream, and vanilla extract.
-
Pour wet ingredients into dry and stir until smooth. Batter will be thicker than wheat cupcake batter—that’s normal for keto baking.
-
Scoop batter into cupcake liners, filling each about ¾ full.
-
Bake for 18–22 minutes, or until a toothpick comes out clean.
-
Cool in pan 5 minutes, then transfer to a cooling rack.
-
Prepare Keystone Pantry Keto Vanilla Buttercream according to package directions. Whip until smooth and fluffy.
-
Frost cupcakes once fully cooled. Pipe, swirl, or spread—your choice!
-
Store in refrigerator and bring to room temp before serving.

❓ FAQ: Keto Cupcake Edition
Can I swap almond flour for coconut flour?
No—coconut flour absorbs far more liquid. The ratio is not 1:1 and cannot be swapped without changing the entire formula.
Can I use monk fruit instead of allulose?
Yes, but erythritol-based blends may crystallize or leave a cooling aftertaste. Allulose gives the smoothest result.
Can these be made dairy-free?
Yes—replace butter with coconut oil and heavy cream with full-fat coconut milk.
Do these need to be refrigerated?
Yes—because the frosting contains dairy. Serve at room temp for soft texture.
Can they be frozen?
Freeze unfrosted cupcakes up to 1 month. Frost after thawing.
What makes the frosting keto-friendly?
Keystone Pantry Keto Buttercream contains no sugar and no net carbs, and is sweetened with allulose instead of artificial sweeteners or confectioner’s sugar.
