I made Keto Lemon Raspberry Muffins that are explosively lemony, studded with raspberries, and actually feel like a cheat without wrecking my macros.

Jump to Recipe

I can’t stop making these Keto Lemon Raspberry Muffins. I adore the sharp lemon zest hitting the sweet raspberries, and the crumb from almond flour actually feels honest, not gummy.

My mom made muffins on Sundays, so I steal that ritual and refuse to give up flavor on keto. They’re bright, tangy, a little messy, and zero guilt breakfast low carb that still tastes like real food.

But mostly I just love biting into a warm muffin and getting that burst of raspberry. I get weirdly happy about it.

Obsessed? Yep.

Trial after trial proved it. No regrets, ever.

Seriously.

Ingredients

Print Recipe (No Advertisments)

Almond flour gives nuttiness and tender crumb, and it’s protein rich.
Basically coconut flour soaks up moisture, making muffins dense yet fluffy.
Powdered erythritol sweetens without sugar and won’t spike insulin.
Baking powder lifts the muffins, so they’re light not flat.
Salt wakes flavors, balances sweetness, tiny but crucial.
Eggs bind everything, add protein, and make it slightly custardy.
Sour cream or Greek yogurt adds tang, moisture, and richness.
Butter melted adds richness; coconut oil gives a subtle coconut note.
Heavy cream makes the batter silkier and richer in texture.
Vanilla extract brings warmth and helps round the flavors.
Lemon zest gives bright citrus punch without extra liquid.
Lemon juice adds real tartness and fresh lemony zip.
Raspberries give bursts of tart sweetness and pretty jammy spots.
Plus an extra powdered sweetener for dusting or a sweeter top.

Ingredient Quantities

1 1/2 cups almond flour

1/4 cup coconut flour

1/2 cup powdered erythritol or powdered erythritol blend

1 tbsp baking powder

1/4 tsp salt

3 large eggs, room temperature

1/2 cup sour cream or full fat Greek yogurt

1/4 cup unsalted butter, melted and cooled (or coconut oil)

1/4 cup heavy cream

2 tsp vanilla extract

1 tbsp lemon zest (from about 1 large lemon)

2 tbsp fresh lemon juice

3/4 to 1 cup fresh or frozen raspberries (if frozen, do not thaw)

Optional: extra erythritol for dusting or 1 tbsp powdered monk fruit for sweeter topping

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 350 F and line a 12 cup muffin tin with paper liners or grease well so they dont stick.

2. In a large bowl stir together 1 1/2 cups almond flour, 1/4 cup coconut flour, 1/2 cup powdered erythritol, 1 tbsp baking powder and 1/4 tsp salt until evenly mixed.

3. In a separate bowl whisk 3 large room temperature eggs, then add 1/2 cup sour cream (or full fat Greek yogurt), 1/4 cup melted and cooled unsalted butter (or coconut oil), 1/4 cup heavy cream, 2 tsp vanilla extract, 1 tbsp lemon zest and 2 tbsp fresh lemon juice. Whisk until smooth.

4. Pour the wet ingredients into the dry ingredients and stir gently until combined. Dont overmix, a few small lumps are fine.

5. Let the batter rest 3 to 5 minutes so the coconut flour absorbs liquid and the batter firms up a bit.

6. Carefully fold in 3/4 to 1 cup fresh raspberries (if using frozen do not thaw). Fold just enough to distribute them without smashing the berries.

7. Divide batter evenly among the 12 muffin cups, filling about 3/4 full. If you like, sprinkle a little extra powdered erythritol or 1 tbsp powdered monk fruit on top for a sweeter dusting.

8. Bake in the preheated oven for 18 to 24 minutes or until the tops are golden and a toothpick inserted in the center comes out mostly clean with a few moist crumbs.

9. Remove muffins from oven and let cool in the tin for 5 to 10 minutes, then transfer to a wire rack to cool completely so they set up and dont crumble.

10. Store leftover muffins in an airtight container in the fridge for up to 7 days or freeze for longer. Reheat gently before serving if you want them warm.

Equipment Needed

1. Oven (preheated to 350 F)
2. 12-cup muffin tin (plus paper liners or grease for it)
3. 2 mixing bowls (one large for dry, one medium for wet)
4. Measuring cups and spoons (accurate for 1/4 cup, tbsp, tsp)
5. Whisk and rubber spatula (or a spoon to fold the batter gently)
6. Zester or fine grater (for the lemon zest)
7. Wire cooling rack and toothpick (for testing doneness)
8. Small saucepan or microwave-safe bowl (to melt and cool the butter or coconut oil)

FAQ

Q: Can I use frozen raspberries and will they make the batter soggy?

A: Yes you can use frozen raspberries. Keep them frozen and fold them in gently so they don't bleed into the batter. Tossing them lightly in a teaspoon of almond flour first also helps keep them from sinking or turning the batter pink.

Q: What can I substitute for powdered erythritol if I dont have it?

A: You can use powdered monk fruit or a 1:1 erythritol blend. If you're using granulated sweetener, pulse it in a blender to powder it so the muffins dont have a gritty texture. Adjust sweetness to taste.

Q: My muffins taste eggy or too dense. How do I fix that?

A: Make sure eggs are room temperature and dont overmix the batter. Overbeating develops structure and makes them dense. Also use fresh baking powder and measure flours by spooning into the cup and leveling to avoid packing too much.

Q: Can I make these dairy free?

A: Yes. Replace butter with melted coconut oil and use canned coconut cream instead of heavy cream and a coconut yogurt for the sour cream. Texture may be slightly different but still tasty.

Q: How do I store or freeze the muffins?

A: Cool completely then store in an airtight container in the fridge for up to 5 days. For longer storage, freeze individually wrapped muffins for up to 3 months. Thaw at room temp or warm briefly in the oven or microwave.

Q: Any tips for extra lemon flavor without adding liquid?

A: Add extra lemon zest or use a tiny pinch of lemon extract. Zest packs lots of aroma without thinning the batter. You can also sprinkle a little powdered sweetener mixed with lemon zest on top after baking.

Keto Lemon Raspberry Muffins Recipe Substitutions and Variations

Almond flour: swap for finely ground sunflower seed flour, 1:1. It bakes the same but can sometimes tint muffins green when mixed with berries or baking soda, so don’t panic if color looks off.
Coconut flour: replace with an extra 1/3 to 1/2 cup almond flour and add one more egg to the batter since coconut flour soaks up lots of liquid.
Powdered erythritol: use powdered allulose 1:1 for less cooling aftertaste and slightly better browning. Watch closely, it browns quicker than erythritol.
Heavy cream: use full fat canned coconut cream 1:1 for a dairy free version, just whisk it smooth first so it’s not clumpy.

Pro Tips

1) Let the eggs and dairy come to room temp. It really helps the batter blend smoother and keeps the muffins from being dense. If you forget, put the eggs in warm (not hot) water for 5 minutes and it will mostly do the trick.

2) Be gentle with the raspberries. Fold them in slowly and stop when you see them mostly distributed. Overmixing or stirring too hard will turn the batter pink and make the muffins gummy. If a couple berries get squished it’s fine, but try to keep most whole.

3) Give the batter that 3 to 5 minute rest. The coconut flour soaks up liquid fast and if you pour right away the batter will be too thin and the texture will be off. If it firms up too much after resting, just fold in a splash more cream or a beaten egg yolk.

4) Bake until a toothpick comes out with a few moist crumbs, not completely dry. Almond flour bakes differently so overbaking makes them dry real fast. Cool in the tin for a few minutes, then transfer to a rack so they set without getting soggy. Reheat gently in a microwave for 10 to 15 seconds or a warm oven so they taste fresh.
