  1. Preheat oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking dish.
  2. Whisk 1 1/4 cup rice flour, confectioners' sugar, and oat flour together in a bowl. Mix butter into flour mixture until evenly combined; press into the bottom of the prepared baking dish.
  3. Bake in the preheated oven until crust is golden brown, about 15 minutes.
  4. Beat eggs together in a bowl until light and smooth. Combine white sugar, 1/4 cup rice flour, and baking powder together in a separate bowl; stir into beaten eggs until just combined. Stir lemon juice and lemon zest into egg mixture; pour over crust.
  5. Bake in the preheated oven until filling is set, about 30 minutes. Cool completely before cutting into bars.

  • Cook's Note:
  • Be sure to use confectioners' sugar for the base. I have used different types of flour (such as brown rice flour) with quite varying results. I'm sure there are others that would work but this one worked great so I stuck with it. It also gives the benefits of oats which aren't too available in gluten-free. If you prefer to substitute regular flour just use equal amounts. And don't undercook by following times rather than descriptions!

I ended up adding an 2 lemons instead if one for more flavor. When it set, I thought I had overlooked it, but it came out with a perfect consistency and flavor. I cut out the bars with a pizza cutter.

They definitely were not lemony enough and too eggy. I would add like 4 lemons and the crust was a little too thick for my taste. Good basic recipe, just needs some tweaking

It does not taste particularly lemony. I don't think I'll use it again...
