Zesty Keto Key Lime Pound Cake! Low-Carb Dream!
Ingredients
Method
- Preheat oven to 325°F (160°C). Grease and flour a 9×5 inch loaf pan with parchment paper, leaving an overhang on the long sides to easily lift the cake.
- In a medium bowl, whisk together almond flour, protein powder, baking powder, and salt. Set aside.
- In a large bowl, cream together softened butter and granular sweetener until light and fluffy. This should take about 3-5 minutes with an electric mixer.
- Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Scrape down the sides of the bowl as needed.
- Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Do not overmix.
- Stir in the key lime juice, water, and key lime zest until evenly distributed. The batter will be thick.
- Pour the batter into the prepared loaf pan and smooth the top. Bake for 50-60 minutes, or until a wooden skewer inserted into the center comes out clean. If the top browns too quickly, tent loosely with foil.
- Let the cake cool in the pan for 15 minutes before carefully lifting it out using the parchment paper overhang. Transfer to a wire rack to cool completely before slicing and serving. For best flavor, chill for at least an hour.
Notes
– Ensure your butter is truly softened (room temperature) for a light and fluffy batter, which is key to a tender pound cake.
– To prevent the top from browning too quickly, tent the cake with aluminum foil during the last 15-20 minutes of baking, or if you notice it getting too dark.
– If the dough cracks when forming, it might be too cold or overmixed. Let it rest a few minutes at room temperature before handling, or knead gently for 1-2 minutes until pliable.
