Ingredients for Paleo Blueberry Crumb Bars

ALMOND FLOUR: Almond flour is a popular Paleo flour for baking.  It’s slightly nutty, a little hearty, and the the perfect flour for these Paleo Blueberry Crumb Bars.

COCONUT FLOUR: A little bit of coconut flour goes a long way.  It balances out the almond flour.

COCONUT OIL: Coconut oil is a great Vegan baking fat.  Use refined coconut oil for no coconut flavor.

MAPLE SYRUP: Pure maple syrup is a delicious natural sweetener!  It is used in both the shortbread layer and blueberry jam.

VANILLA EXTRACT: Just a little bit is added to the shortbread layer.

BLUEBERRIES: The heart of the jam is fresh blueberries.  If using frozen, thaw completely then squeeze out all excess water.

LEMON JUICE: Lemon juice really brings out the flavor of the blueberries.

TAPIOCA FLOUR: Similar to cornstarch, tapioca flour thickens the homemade blueberry jam layer.

WATER: If the blueberry jam is too thick, add a little bit of water at a time.

How to Make Homemade Jam for Blueberry Crumb Bars

Most jams and jellies aren’t Paleo friendly.  They oftentimes contain added preservatives and sugars.  While these taste great and are convenient, making homemade blueberry jam is super easy!  Simply bring the jam ingredients to a light simmer in a skillet.  Simmer for 4 to 5 minutes, or until mixture has started to thicken.  Break apart blueberries with a spatula.  For a more runny jam, add water until desired consistency is reached.  Store in the fridge for up to 4 days.
