Strawberry Oatmeal Bars – (Gluten Free & Vegan) Sweet Breakfast Bar

Fresh strawberries combine with old fashioned oats in these gluten free strawberry oatmeal bars. The bars have a buttery crumb crust, a sweet strawberry filling inside and a tasty and crunchy crumble on top. They are a great way to use up fresh strawberries for a dessert that everyone will love. I have included both a gluten free and vegan version of the recipe.

It will soon be strawberry season and I can’t wait to start making bar recipes with them.  Fortunately our grocery stores have a good stock of strawberries all year long, so we don’t have to miss out on fresh strawberry desserts just because the weather is cold.

These strawberry oatmeal bars have been adapted to be gluten free (with vegan adjustments, as well) They are easy to make, fresh tasting and delicious

You can still enjoy tasty desserts when you are trying to follow a gluten free or Vegan diet. (See my maple syrup date bars for another fruity dessert idea that fits both plans.)

Fresh (and frozen) Strawberries are naturally sweet. You can use them in desserts without having to add a lot of extra sugar to flavor them.  (Check out these delicious cupcakes with a strawberry buttercream frosting for another tasty dessert idea.Fresh strawberries

Making these gluten free strawberry oatmeal bars

It is very easy to adapt most dessert recipes to make them gluten free. For today’s recipe I am using baking soda and cream of tartar in place of baking powder, and Gluten free all purpose flour in place of normal flour. Oats are considered gluten free but if you are worried about cross contamination, you can also use gluten free rolled oats.

Start with your strawberries.  Remove the stems and blend 1/2 of them and set them aside. Slice the other half of the strawberries into big chunks.Sliced strawberries and strawberry puree

Place ½ of the strawberry puree into a small bowl and add the cornstarch. Mix well and put the rest of the pureed strawberries into a saucepan along with the puree and cornstarch mixture. Cook over medium high heat until everything is well combined.Strawberry puree with cornstarch

Now add the chunks of strawberries, the lemon juice and the granulated sugar. Bring the mixture to a boil, stirring the whole time. Cook until the puree thickens and set the pan aside to cool.I don’t like to use too much sugar, so I added just a third cup. If you like your filling sweeter, you can add more.

Add fresh strawberries and sugar

The mixture will be sort of like a cooked strawberry jam.  If you want it to be a thicker consistency, you can add more chopped strawberries. Set this mixture aside while you make the crumb crust and topping mixture.Cooked Strawberry filling.

Let’s make the crumb crust.

Combine all of the ingredients for the crust in a food processor and pulse until you have a nice crumbly mixture. Making a crumble base

½ of the crumb mix goes in the bottom of a 9 x 13″ pan. I find it helps to line the pan with parchment paper to make it easier to remove the bars later.

Pour the strawberry sauce over the crust, being sure to leave a space of about ½” all around the edges with no strawberry topping on it.

Add strawberry filling on the crumble base

Add with the remainder of the crust mixture over the strawberry mixture and bake in a preheated oven for 35 to 40 minutes until the crumble is browned and the strawberry filling is bubbly.Baked strawberry oatmeal bars

The bars must be completely cooled before you try to slice them.  The filling is quite soft when it comes out of the oven and needs time to set so the bars will hold their shape.

Vegan adaptations for the strawberry oatmeal bars.

This recipe is fine for a gluten free diet but needs a few adaptations to make it vegan since butter and sugar are both a no no on this diet.

To make this recipe suitable for vegans, use maple syrup instead of granulated sugar in the filling, and use room temperature firm coconut oil in place of butter and pure maple sugar in place of brown sugar in the crumble.Serving dish and strawberry oatmeal bars on a plate - Gluten free and vegan adjustments!
