Instructions
Get Ready: Start by preheating your oven to 325°F (160°C). Lightly grease a 9x5 inch loaf pan, preparing it for your delicious cake.
Mix Dry Ingredients: In a medium bowl, whisk together the almond flour, protein powder, baking powder, and salt until well combined. Set this dry mixture aside.
Cream Butter & Sweetener: In a separate large bowl, beat the softened butter and granular sweetener together until the mixture is light, pale, and fluffy. This usually takes about 2 minutes.
Add Eggs: Incorporate the eggs one at a time into the butter mixture, beating well after each addition until everything is smoothly blended.
Combine Wet & Dry: Gently beat in half of the prepared dry almond flour mixture. Next, add the key lime juice, water, and lime zest, mixing just until combined. Finally, fold in the remaining dry mixture until you have a smooth, luscious batter.
Bake to Perfection: Pour the batter evenly into your greased loaf pan and smooth the top. Bake for 55 to 65 minutes. To prevent the top from getting too dark, loosely cover the cake with aluminum foil halfway through the baking time. The cake is perfectly done when its edges are golden and the center feels firm to the touch.
Cool & Glaze: Allow the cake to cool completely in the pan on a wire rack before carefully removing it. While it cools, prepare your simple glaze: whisk the powdered sweetener and key lime juice together until smooth and slightly runny. Drizzle this bright glaze generously over your cooled pound cake for that extra citrusy zing.
