Ever asked yourself the question, “Can I bake with olive oil?” 

The answer is a resounding YES!!! You can substitute olive oil for other cooking oils in most baked recipes, such as quick breads or olive oil brownies. Olive oil does have a stronger flavor than some other oils, which might affect the flavor of the baked product, but that is what we are actually going for with this cake!

This olive oil cake is the stuff that dreams are made of. There is no waiting around for a stick of butter to soften for this recipe and it comes out incredibly moist and tender every single time! When the urge strikes or the need arises you can get to baking immediately and have a perfectly decadent dessert ready in under an hour!

You may have noticed that I have been cooking with grapes a lot lately! 

What household doesn’t have a crisper drawer FULL of grapes these days?! You can use red, green, or purple grapes for this gluten free olive oil cake recipe, the color doesn’t really matter, it is just important that whatever variety you use is seedless. We all know that grapes taste great, but did you know that grapes are loaded with nutritional benefits too?

Grape Benefits

Are grapes good for you? Of course! Grapes are packed with loads of nutrients, especially vitamin C, vitamin K and antioxidants which help to ward off chronic disease. Diets that are high in antioxidant-rich foods, such as grapes, have been linked to a lower risk of cancer.

Ingredients

Scale

1 cup gluten free all-purpose flour

1/2 cup almond meal or almond flour, see note

1/4 cup polenta

1 1/2 teaspoons baking powder

1/2 teaspoon kosher salt

2 large eggs

2/3 cup sugar

Zest of 1 large lemon

1/2 cup good quality extra-virgin olive oil,plus more for pan

1/3 cup whole milk

2 cups red seedless grapes

Instructions

Preheat the oven to 350°F. Brush an 8-inch square or round pan with olive oil then dust with gluten free flour, tapping out the excess.

Spread the almond flour on a parchment lined baking sheet and toast in the oven until fragrant, about 5 minutes. Set aside. ****

In a mixing bowl whisk together the flour, toasted almond meal, polenta, baking powder, and salt. Set aside.

In the bowl of an electric mixer fitted with the paddle attachment beat the eggs, sugar, and lemon zest on high speed until pale and fluffy. Reduce speed to low; slowly stream in the olive oil. Beat in the flour mixture in 3 additions, alternating with milk, beginning and ending with flour.

Spoon the batter into the prepared pan and scatter the top with half of the grapes. Bake for 15 minutes. Scatter the remaining grapes over the cake. Bake until golden brown and a toothpick inserted in the center comes out clean, about 25-27 minutes more. Let cool in the pan on wire rack for 15 minutes. Turn out and slice into pieces.

Notes

Don’t have almond meal or almond flour handy? You can make your own!

Here is how to make almond meal at home:

Toast raw almonds in a 325°F oven until golden brown and fragrant, cool completely. Pulse the toasted almonds into a powder in a food processor fitted with the ‘s’ blade to measure 1/2 cup.

    Hi there,
    Randomly came across your recipe when I googled ‘gluten free’ and ‘grapes’, looking for something to bake to use up grapes grown by family. This recipe sounded and looked great. I adjusted the recipe a little as I didn’t have any pre-mix GF flour (I used a combo of buckwheat, rice and potato), and I had only coconut sugar. The texture is wonderful, and I like the baked grapes (though worth noting it’d be better with seedless grapes!). Alas, I used less than the half teaspoon of salt and still found it rather salty.. I’d suggest a pinch or two would suffice. Hoping my workmates will still eat this with a cuppa tomorrow. I’d like to bake it again with less salt. Thanks for the recipe!

      Polenta is similar to yellow cornmeal:) Check out this link: http://en.wikipedia.org/wiki/Polenta
      It is an amazing and super versatile ingredient. Of course, if you do not have polenta you can substitute coarsely ground yellow cornmeal. in this recipe.
