Tips for the Best Keto Cinnamon Muffins

Use finely ground almond flour. Blanched almond flour gives these muffins a softer texture than coarse almond meal.

Don’t overmix the batter. Stir just until everything is combined to keep the muffins tender.

Use a brown sugar-style monk fruit sweetener for the topping. This gives the cinnamon streusel a richer flavor similar to traditional coffee cake.

Use parchment paper liners. Keto baked goods made with almond flour can stick to traditional paper liners. Parchment liners help the muffins release easily without tearing or leaving half the muffin behind.

Let the muffins cool. Almond flour baked goods are delicate when warm. Allowing them to cool helps them hold their shape.

How to Store Keto Cinnamon Streusel Muffins

Store leftover muffins in an airtight container in the refrigerator for up to 5 days.

For longer storage, freeze the muffins in a freezer-safe container or bag for up to 2 months.

When you’re ready to enjoy one, warm it briefly in the microwave for that freshly baked taste.

Absolutely! These keto cinnamon muffins are a great make-ahead breakfast or snack. Bake a batch at the beginning of the week and keep them refrigerated for a quick, low-carb treat whenever you’re craving something sweet.
