Preheat your oven to 375°F (190.5°C).
Line a large baking sheet with parchment paper or a silicone mat.
In a medium bowl, whisk together the almond flour, all-purpose flour, baking powder, sugar, and salt.
Add the egg, almond milk, olive oil, and vanilla extract to the bowl with the dry ingredients.
Use a micro plane grater and grate the beets into a separate bowl. Add 2 tablespoons of the grated beets into the bowl with the rest of the ingredients.
Using a spoon, stir all the ingredients until just combined—be careful not to overmix!
Fold in the chocolate chips.
[1] Use a tablespoon and place a spoonful onto the baking sheet. [2] Then, place another spoonful almost diagonal to the first one. [3] Using your spoon, form the two spoonfuls into a heart shape. Repeat with the rest of the batter to form 4 total muffin tops. Divide any leftover batter among the 4 formed heart shapes. Fold some aluminum foil and use it to secure the top of the heart shapes.
Bake at 375°F for 18-20 minutes or until the edges are slightly firm to the touch and a toothpick comes out clean.
Let these cool on the baking sheet for about 5-10 minutes.
