Tangy keto lemon poppyseed muffins are ultra moist inside and take about 25 minutes to make from start to finish!
Costco poppyseed muffins were my absolute favorite in high school. It was obvious my thighs also loved them because that’s where they went… straight to my thighs. LOL! Since I’ve been making low-carb muffins like keto gingerbread muffins and chocolate zucchini muffins, I found a way to still enjoy this fluffy grab-and-go baked good without the worry of packing on the lbs! Plus, I added lemon to these!!

What makes these muffins keto?
- Uses keto flours – Instead of wheat based flour, this recipe uses almond flour and coconut flour. I like the combination of the two flours. When used together they provide a similar consistency to all-purpose flour.
- Sugar-sweetener – Instead of sugar, I use sugar-free sweeteners. Look for a sweetener with a combination of either monkfruit, erythritol, stevia or allulose. Combination sweeteners taste and act more like baking sugar. Plus many measure cup for cup with sugar.
- Still fluffy thanks to key ingredient – One of the downsides of not using all-purpose flour is that most keto flours don’t contain gluten. Gluten is what helps to create fluffy muffins with a puffy muffin top. To get the same results, this muffin recipe uses eggs. The protein in the egg whites works similar to gluten (which is a protein) to make fluffy muffins. To decrease the eggy flavor, cream cheese is added. I use cream cheese, sour cream or yogurt in many baked goods to neutralize eggy flavors.

Is there a substitute for cream cheese? Like avocado oil mayonnaise or a healthier fat?
I haven't tried any substitutions, so I'm not how well these will work, but you could try blended cottage cheese, greek yogurt or ricotta cheese. I'd may say 1/3-1/2 cup.
