Here is what you’ll love about Oatmeal Raisin Bars
- The recipe might look complicated, but it is straightforward to make.
- The top and bottom layers are made from the same dough base, and the jam comes together, over the stove, in very little time.
- The ingredients are probably in your cupboard right now.
- They are made from wholesome, familiar flavors and a go-to recipe to please a crowd.
What Are The Three Layers?
- These treats have a slightly crunchy oats-cookie-dough base and are sweetened with organic brown sugar.
- In the middle, there's a not too thick raisin-and-orange flavored filling—my homemade raisin jam—with a perfect hint of tropical coconut pieces.
- Then, of course, the peanut crumb topping finishes it off.
- When you add the ingredients for the filling in the saucepan, it is essential to frequently stir at first until all the sugar and cornstarch has dissolved.
- Then you let it cook over medium heat until thickened and you get that marmalade effect.
- Cornstarch slightly thickens the fruit mixture to a lovely jam-like consistency.
- Don’t forget to add the orange juice. It is going to give you that tangy, slightly sweet flavor that beautifully compliments dried fruits like raisins.
- It is the juice that makes the taste of the filling so unique.
- Stir in the coconut shreds at the end when the jam has thickened. It adds a great chewy texture.
- Chop the peanuts as fine as you like. Two different versions of these easy oatmeal bars are featured on these pages and they all taste fantastic!
You can substitute coconut sugar for the brown sugar.
If you prefer less sweet crumb bars, opt for coconut sugar. Although it looks a lot like brown sugar, it is less powerful in taste and when used in baking a tad less sweet.
Can you make these easy oatmeal bars nut-free?
If you prefer your crumble on the softer side or want to make it allergy-friendly and nut-free, simply remove the chopped peanuts.
Don’t have a strong opinion about it? Then do yourself a favor and add the nuts. I think the crumble topping is a winner!

Oatmeal Raisin Bars
For the Filling:
- 1 tablespoon sugar
- 1 tablespoon cornstarch
- 1 ¼ cups raisins
- ¾ cup orange juice
- ½ cup shredded coconut
for the base and crumb mixture
- 1 cup all purpose flour
- 1 cup old fashioned oats (also called rolled)
- ⅔ cup brown sugar, packed - you can also use coconut sugar instead
- 1 teaspoon baking soda
- ½ cup dairy-free butter
- ½ cups chopped peanuts
- Do the raisin filling first so it can cool a bit while you are working on the crumb mixture.
For the Filling:
- In a medium sized saucepan add the sugar and cornstarch.
- Stir in the raisins and orange juice. Do not add the coconut yet.
- Cook over medium heat until thickened. Take off the heat and stir in the coconut. Set aside.
For the crumb mixture:
- In a large bowl add the flour, oats, brown sugar and baking soda. Mix together.
- Add the dairy-free butter and cut in until the mixture resembles crumbs.
- Remove ½ cup of the crumb mixture and put in a small bowl. Add the peanuts and set aside for the topping.
- With your fingers - press the remaining crumb mixture in an ungreased 9"x9" baking pan.
- Spread the raisin mixture all over the bottom layer.
- Evenly sprinkle the peanut mixture over the top. Press gently into the raisin mixture.
- Bake at 350 degrees for 30 to 35 minutes.
- Cool in the pan on a wire rack. Cut into squares. Makes about 20 bars depending on the size that you cut your squares.
They defrost quickly so it really doesn't take any planning. Just put them on a plate for an hour or two and enjoy.
