Inspiration for recipes come from many places... a picture from a magazine, a Google search on an ingredient, from ingredients on hand or my desire to a recreate an old favorite. Sometimes inspiration emerges from an intense craving for a specific taste.

The idea for these Keto cranberry crumb bars popped into my brain the other day at the grocery store. There was no seeking for inspiration, it just jumped right into my brain... probably because I had a mad craving for cranberries. I always do this time of year.

Low Carb Shortbread Crust

This low carb shortbread crust recipe is perfect for these keto cranberry crumb bars. Although it's not a recipe for actual shortbread cookies, it's a great keto crust I use in several low carb desserts on the blog. It's featured in my low carb blueberry crumble bars and also in my keto strawberry cream cheese bars. Made of almond flour, shredded coconut and protein powder, this crust compacts well and resists sogging.

I know some people don't like coconut. I chose unsweetened shredded coconut for this shortbread recipe because it helps lower carbs and resists absorbing moisture. Sub with additional almond flour if you must, but the texture will be completely different. Protein powder helps lighten the mixture and provides the right texture.

The only work the crust requires is processing the coconut into a powder. I use a mini food processor or coffee/spice grinder for this task. It only takes a few seconds. Stir the dry ingredients together and stir in the melted butter to form a rumbly mixture. Remove a portion of the mixture to use on top as the crumb layer. Press the rest into a parchment lined square pan.

I also use this crust as the base for my low carb chocolate lasagna and low carb lemon lush recipes. There is also a peanut butter version.

Use Fresh or Frozen Cranberries

Use fresh or frozen cranberries in these keto cranberry bars and cook them like a Thanksgiving cranberry sauce. There's no need to halve or chop them, cook the cranberries whole until they pop and the sauce thickens. Then cool slightly. A low carb erythritol based sweetener keeps carbs low and lemon juice brightens overall flavor. A little spice warms it up and reflects the season.

Keto Cranberry Bars Are Easy to Assemble

After making the crust mixture and reserving a portion for the crumb topping, press the crust into a parchment lined square baking pan. I have a 9x9 inch pan and it was perfect. The parchment helps with removing the cranberry crumb bars later. To press the crust into the pan, I evenly distribute the crust, cover with a piece of waxed paper, then press down very firmly with a flat bottomed glass.

Spoon the filling onto the crust and spread evenly. Then, top with the crumb mixture, chopped walnuts, sugar free chocolate chips and a little low carb brown sugar. Bake in a 350 F preheated oven for 30 minutes or until the top turns golden brown. Cool completely before removing from the pan and cutting.

Storing and Freezing

Store the cranberry bars in the refrigerator in an airtight container for up to a week or in the freezer for up to 3 months. Thaw in the refrigerator overnight. The bars taste good cold and at room temperature.

Ideas for Customizing

I love to bake. Part of the joy of baking, low carb and keto baking included, is the endless ways recipes can be combined. Here are some ideas to take these keto cranberry crumb bars to new levels:

use the chocolate shortbread base from the Low Carb Chocolate Lasagna recipe
add grated chocolate, sugar free chocolate chips or keto white chocolate chips to the base before adding the cranberry sauce
add any of these flavors to the cranberry sauce: vanilla extract, almond extract, orange extract, raspberry flavoring, brandy, or spiced rum
top with flaked almonds, flaked coconut, pecans, macadamia nuts, pine nuts, or keto white chocolate chips

If you want to purchase a 9x9 inch square brownie pan, try this pan or this one from Amazon. They seem to be sturdily constructed and are similar to the pan I purchased 15 years ago from a restaurant supply store.
