Step 1: Preheat and Prep

Step 4: Bring It All Together

Step 5: Bake
- Pour the batter into your prepared loaf pan and smooth the top with a spatula.

- Let the loaf cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
Step 6: Enjoy!
- Once cooled, slice your loaf and enjoy it plain, or top it with a dollop of whipped cream or a drizzle of keto-friendly glaze for extra indulgence.
Baking Tip: If the top of your loaf starts to brown too quickly, cover it loosely with aluminum foil halfway through baking to prevent over-browning.
Tips and Variations for the Perfect Loaf
One of the best things about this Key Lime Bread Coconut Cake Loaf is how versatile it is. Here are some tips and variations to make it your own:
- Add a Crunch: Sprinkle some chopped macadamia nuts or almonds on top before baking for a delightful crunch.
- Boost the Coconut Flavor: Swap out the almond milk for coconut milk to enhance the coconut taste.
- Make It Dairy-Free: This recipe is already dairy-free, but if you want to add a glaze, use coconut cream instead of heavy cream.
- Try a Different Citrus: Not a fan of lime? Swap the key lime juice and zest for lemon or orange for a different citrus twist.
- Make It Mini: Instead of one large loaf, divide the batter into muffin tins for individual keto-friendly treats. Just reduce the baking time to 20-25 minutes.
