Ingredients for Poppy Seed Lemon Cupcakes
These keto lemon cupcakes are made with ten simple ingredients you probably already have in the kitchen.
- Almond flour - Keeps the cupcakes low in carbs. Use super-fine, unblanched almond flour.
- Coconut flour - You'll also need super-fine coconut flour for these cupcakes.
- Greek yogurt - Unflavored and unsweetened at room temperature.
- Eggs - Free-range at room temperature.
- Erythritol - This will be the sweetener for the cupcakes. I used granulated Erythritol, but you can substitute it with sugar-free sweeteners like monk fruit or stevia. Just make sure you use a granulated variety.
- Butter - Use high-quality, unsalted butter that is softened at room temperature.
- Lemon - Use the juice and zest of one lemon.
- Poppy seeds - Adds crunchy texture and delicious nutty and earthy aroma.
- Baking powder - Helps make the cupcakes light and fluffy.
- Vanilla extract - High-quality pure vanilla extract will give your cupcakes the best flavor.
How To Make Lemon Poppyseed Cupcakes
- Preheat the oven to 375 degrees Fahrenheit (190 degrees Celsius) and line a muffin tray with cupcake liners.
- In a large mixing bowl, whisk together the almond flour, coconut flour, Erythritol, poppy seeds, baking powder, and salt.
- In another mixing bowl, whisk together the eggs, Greek yogurt, lemon juice, lemon zest, butter, and vanilla extract.
- Combine the wet and dry mixtures until well mixed.
- Pour the cupcake batter into the lined muffin tray and bake in the oven for 10 to 15 minutes.
- Allow the cupcakes to cool to room temperature.
- Optionally make keto buttercream frosting and frost the cupcakes. Sprinkle with extra poppy seeds.
- Refrigerated: Keep leftover cupcakes covered or in an airtight container. They will keep for up to 2 days. Before eating the cupcakes, let them reach room temperature, so the buttercream has softened.
- Frozen: These cupcakes freeze great as well. Store them in an airtight, freezer-proof container. They will keep for up to 3 months.
