Tips For the Perfect Sugar Free Lemon Poppy Seed Cake
When making Keto Lemon Poppy Seed Cake, there are a few things to keep in mind.
- Use a quality nonstick tube pan or bundt pan
- Make sure all your ingredients are at room temperature before you start baking, so everything blends together smoothly and evenly.
- Prep the pan: Properly grease your tube pan or bundt pan to prevent sticking.
- For an extra burst of lemon flavor: Consider adding some freshly grated lemon zest to the batter.
- Don’t over-mix the batter once you add in the dry ingredients – just mix until everything is combined.
- Don’t over-bake your keto lemon cake: Remove your cake from the oven when a knife or skewer comes out clean.
- Cooling is also important: Allow the cake to cool in the pan for about 10 minutes before flipping it out onto a cooling rack.
- Clean your bundt pan properly: If you use baking spray, note that baking sprays can leave a residue that builds up and turns into a sticky cake glue that refuses to let go of your cake sponge. So, always clean your cake pan properly.
Regardless of whether you use butter or baking spray, I recommend washing cake pans with Dawn Powerwash Spray after every bake. Simply apply the Powerwash Spray directly to pan, no water, and let it stand 10 minutes.
Then wipe it off or, if necessary, scrub the pan well with a plastic or nylon bristled brush, and finally rinse with hot water.
By following these tips, you’ll be well on your way to creating a beautiful, delicious gluten free lemon poppy seed cake.
