Easy Keto Coffee Cake: A Perfect Companion to Your Morning Brew

The traditional coffee cake uses high-carb ingredients like wheat flour and brown sugar. Our keto recipe replaces those with almond flour and a keto-friendly Lakanto Monk Fruit sweetener, respectively.

Not as a straight swap. Coconut flour drinks up far more liquid than almond flour does, so the same amount would turn this batter to paste — correcting for that means changing the flour, the eggs and the sour cream together, and those amounts are not part of this recipe.

Almond flour is what it is built on: 2½ cups in the cake and another 2 in the crumble.

Yes — a teaspoon stirred into the batter with the sour cream. Vanilla and cinnamon get along, and it rounds the crumb out without competing with the crumble.

It is what keeps the cake soft. Almond flour goes dry and crumbly easily, and the fat and acidity in a cup of sour cream are what stop this one doing that.

Half a cup instead of the full cup gives you a denser cake, if that is what you are after.

This cake is built on a granulated monk fruit blend that measures 1:1 with sugar, and three quarters of a cup of it goes in across the cake and the crumble. At that volume the sweetener is doing more than sweetening: it creams with the butter, and in the crumble it is part of what makes crumbs.

Another granulated 1:1 blend is the like-for-like swap, and erythritol blends are usually sold that way — check the packet, since equal sweetness is not the same as equal bulk, and bulk is what this recipe is using it for. What will not work is a concentrated sweetener. Pure stevia or a liquid gives you the sweetness in a few drops and leaves a hole where three quarters of a cup used to be.

If you are shopping for a replacement, our monk fruit sweetener guide explains how the granulated, powdered and golden blends differ.

Yes. Cool it completely first, then wrap it tightly and box it — cake left unwrapped in a freezer dries at the cut edges and picks up whatever else is in there.

To serve it again, warm a slice in the microwave in 10-second bursts, or give it about 8 minutes in a 350°F oven.

Nuts, easily — chopped pecans are already an option in the crumble, and almonds work the same way. They go in dry either way.

Berries are a different matter. They carry a lot of water into a batter that is already wet, so adding them changes how the cake sets. This recipe does not give an amount or a baking adjustment for them.

With coffee, which is where it got its name. Beyond that it does not need anything — but a dollop of whipped cream, a drizzle of sugar-free maple syrup or a thin glaze all suit it if you are putting it on a table for other people.

Xanthan gum is a binding agent in gluten-free baking, like in this keto coffee cake recipe. It helps improve the texture of the cake and prevents it from falling apart, making slicing easier.
